50+ Early-Stage French Startups to Watch — Pre-Seed to Series A, 2021–2025

France is in a weird spot. Everybody knows about Mistral, Qonto, Alan, Pigment. Those are late-stage companies now — not what we're looking at here.

Below: 55 companies that most people outside France have not heard of. Pre-seed, seed, Series A at most. Founded 2021–2025. Under $20M raised (most under $10M). Small teams, early traction, interesting bets.

Sources: YC W22–W25 batches, Hexa (eFounders) studio, Station F Future 40 (2023 and 2024), Entrepreneur First Paris, eu-startups.com, TechCrunch EU, Sifted, FrenchTechJournal, and direct research on individual companies.

1. Developer Tools & Infrastructure

1. Nango — Open-Source Product Integrations (YC W23)

URL: nango.dev

Founded: 2022

Funding: Pre-seed ($500K from YC). Passed $1M ARR with 6 people, growing via PLG.

Founders: Robin Guldener and Bastien Beurier. Bastien is French-American, grew up in Paris, previously founded Lantern (YC S19).

What they build: Open-source platform for product integrations. 400+ APIs, 600+ pre-built integrations, OAuth handling, and custom integrations-as-code. Powers integration layers for Linux Foundation, Semgrep, and Contentful.

Why it's interesting: Every SaaS company builds integrations from scratch and wastes months. Nango turns that into a commodity. The open-source angle drives bottom-up adoption. Tiny team, real ARR, zero marketing spend — pure developer word of mouth.

Sector: Developer Tools / Infrastructure

2. Kestra — Open-Source Workflow Orchestration

URL: kestra.io

Founded: 2021

Funding: $3M pre-seed (2023), then $8M seed (Sept 2024) led by Alven, with ISAI and Axeleo. Series A of $25M announced March 2026 led by RTP Global. Total: $36M.

Founders: Emmanuel Darras (CEO) and Ludovic Dehon (CTO). Darras co-founded Ankama, the studio behind the online game Dofus.

What they build: Open-source declarative orchestration platform for complex workflows, designed as a Kubernetes-native alternative to Airflow and Prefect. YAML-based, language-agnostic, with a UI and 500+ plugins.

Why it's interesting: Backed by engineers at Datadog, Hugging Face, Algolia, Airbyte — the who's who of data infrastructure. The $8M seed round in 2024 with those angel names is a strong signal. They are going after the enterprise orchestration standard, a massive and sticky market.

Sector: Data Infrastructure / Developer Tools

3. Brainboard — Visual Cloud Infrastructure (YC W22)

URL: brainboard.co

Founded: 2019 (YC W22)

Funding: $2.4M total. Pre-seed led by Kima Ventures and YC.

Founders: Chafik Belhaoues (former CTO of Scaleway) and Jeremy Albinet.

What they build: Collaborative visual platform for designing and managing cloud infrastructure with Terraform. Engineers drag-and-drop architecture diagrams and generate working Terraform code. $1.5M in revenue, 12 employees.

Why it's interesting: Chafik ran infrastructure at Scaleway, one of the most respected French cloud providers. He knows the problem from the inside. The visual-first approach to Terraform is genuinely different from everything else on the market.

Sector: Developer Tools / Cloud Infrastructure

4. dottxt — Structured Outputs for LLMs

URL: dottxt.ai

Founded: 2023

Funding: $3.2M pre-seed (Elaia, 2023), then $8.7M seed led by EQT Ventures (Aug 2024). Total: $11.9M.

Founders: Rémi Louf, Dan Gerlanc, and Brandon Willard. Background in statistical modelling and compiler technology, previously at Normal Computing in New York.

What they build: The reliability layer for LLM outputs. Their open-source library Outlines forces language models to produce valid, structured responses — JSON, regex patterns, code schemas. 2.5M+ downloads. The commercial product dottxt.ai is built on top.

Why it's interesting: Structured generation is a fundamental unsolved problem in AI. Outlines has become the de-facto open-source solution. Angels include Julien Chaumond (Hugging Face CTO), Jean-Louis Queguiner (Gladia CEO), and Erik Bernhardsson (Modal Labs CEO) — a very strong technical validation signal.

Sector: AI Infrastructure / Developer Tools

5. Defer — Zero-Infrastructure Background Jobs (YC W23)

URL: (acquired / merged)

Founded: 2022

Funding: YC W23, pre-seed only.

Founders: Charly Poly and Bryan Frimin.

What they build: Turn any Node.js function into a background job with zero infrastructure setup. No queues, no workers, no devops. Fully managed, integrates in one line of code.

Why it's interesting: Bryan Frimin is also the co-founder of Probo (compliance, listed below). The background jobs problem is exactly the type of "boring but painful" infrastructure that YC loves, and the developer experience angle — zero infrastructure — is a genuinely elegant take.

Sector: Developer Tools / Infrastructure

6. Koyeb — Serverless Global Deployment Platform

URL: koyeb.com (acquired by Mistral AI, Feb 2026)

Founded: 2020

Funding: $1.6M pre-seed (2020), then $7M seed led by Serena (Nov 2023). Total: $8.6M.

Founders: Bastien Chatelard, Edouard Bonlieu, and Yann Léger — all former Scaleway engineers.

What they build: Deploy apps, APIs, and databases globally on a serverless platform with micro-VMs. Edge deployment with automatic geo-routing, no devops required.

Why it's interesting: The Scaleway alumni network is real — Brainboard's founder was also at Scaleway. Koyeb was doing something genuinely innovative with micro-VMs for cold-start performance. Mistral's acquisition in 2026 validates the tech: they bought it to power their own cloud infrastructure. Not a bad outcome for a 13-person team.

Sector: Cloud Infrastructure / Developer Tools

7. Phospho — GenAI Application Monitoring (YC W24)

URL: phospho.ai

Founded: 2023

Funding: €1.7M pre-seed led by Elaia (Jan 2024), with YC.

Founders: Pierre-Louis Biojout (CTO, École Polytechnique) and Paul-Louis Venard (CEO).

What they build: Analytics and monitoring layer for generative AI applications. Track user conversations, detect edge cases, extract insights from LLM logs. Later expanded into AI robotics tooling.

Why it's interesting: One of the very few French YC W24 companies. Elaia led both this and the dottxt pre-seed — Elaia is emerging as the go-to early-stage fund for French AI infra. The monitoring-for-LLMs space is crowded but phospho is genuinely early.

Sector: AI Infrastructure / Developer Tools

8. Quack AI — Developer Onboarding for Open Source (YC S23)

URL: quackai.com

Founded: 2023

Funding: $500K (YC + Entrepreneur First + Agoranov).

Founders: François-Guillaume Fernandez. CentraleSupélec graduate, formerly led research at Mindee (YC W21), top PyTorch contributor.

What they build: AI companion for developer onboarding in software companies and open-source projects. VSCode extension + maintainer tooling that sequences contribution steps and streamlines onboarding flows.

Why it's interesting: Open-source maintainers waste enormous time on onboarding. François-Guillaume has the credibility — he was running AI research at Mindee and is a known figure in the PyTorch community. Very focused niche.

Sector: Developer Tools

2. AI Agents & Productivity

9. Dust — Enterprise AI Assistants

URL: dust.tt

Founded: 2022

Funding: $5.5M seed led by Sequoia (June 2023), then €15M Series A led by Sequoia (June 2024). Total: $21.5M.

Founders: Stanislas Polu (formerly OpenAI engineer) and Gabriel Hubert (formerly lead product at Alan, before that Stripe).

What they build: AI-powered custom assistants connected to internal data sources (Notion, Slack, GitHub, etc.) for enterprise teams. Not one generic assistant — a platform to build and deploy role-specific AI agents across the company.

Why it's interesting: Stan Polu is arguably the most credentialed French AI engineer — he published the key paper on LLM reasoning at OpenAI. Gabe Hubert built product at Alan. Two operators who've worked at the world's best AI and SaaS companies, now building in Paris. Sequoia backing twice is a very strong signal.

Sector: AI Agents / Enterprise Productivity

10. Tandem — In-App AI Agents for Users (Hexa HX24)

URL: usetandem.ai

Founded: 2024

Funding: $3.8M seed led by Tribe Capital.

Founders: Christophe Barre and Manuel Darcemont, launched from Hexa studio.

What they build: A persistent "Do it with AI" button embedded inside B2B SaaS products. Users click and the agent completes tasks — setup, configuration, form-filling — on their behalf. Already integrated into Qonto, Aircall, and Sellsy.

Why it's interesting: The activation problem in SaaS is real: 64% of new users never activate. Tandem attacks this at the root. Getting into Qonto and Aircall as initial integrations is a very credible go-to-market. Tribe Capital (Docker, Kraken, Airtable) is a meaningful US backer.

Sector: AI Agents / SaaS Infrastructure

11. Topo — AI Sales Agent (YC W24)

URL: topo.io

Founded: 2023

Funding: ~$1.1M pre-seed (YC + angels).

Founders: Dan Elkaim, Léonard Henriquez, and Robin Philibert. 12 employees in Paris.

What they build: AI sales agent trained on a company's specific knowledge and data. Finds leads in industry-specific channels, then automatically contacts prospects with personalized outreach. Full-stack outbound automation.

Why it's interesting: One of the very few YC W24 companies from France. The "AI SDR" space is hot globally; Topo is betting on being the European-native version with a stronger focus on B2B personalization.

Sector: AI Agents / Sales

12. Zeliq — AI-Powered Sales Stack

URL: zeliq.com

Founded: 2023

Funding: €5M pre-seed (May 2023), then $10M seed led by Exor Ventures (June 2024). Total: $15.4M.

Founders: Dorian Ciavarella (previously founded Hivency, exited to Skeepers for 8 figures), Guillaume Cruz (COO), and Victor Lennel (CTO).

What they build: All-in-one sales platform: prospect identification, LinkedIn profiling, AI personality analysis, and automated personalized outreach in one place. Replaces a 4–6 tool stack with a single platform.

Why it's interesting: Dorian's previous exit proves he can build, sell, and scale. The "whole stack in one" bet is contrarian — most tools specialize. The Exor Ventures lead (the Agnelli family office) is an unusual but credible backer for European B2B SaaS.

Sector: AI Sales / B2B SaaS

13. Steerlab — AI RFP Automation (Station F Future 40, 2024)

URL: steerlab.ai

Founded: 2023

Funding: $1.9M seed.

Founders: Rami Iguerwane.

What they build: AI platform for automating RFP (Request for Proposal) responses. Pre-sales teams at enterprise companies spend weeks filling out lengthy questionnaires for procurement. Steerlab automates the drafting from a company's existing knowledge base.

Why it's interesting: RFP automation is a genuine pain point at every mid-market and enterprise SaaS company. The problem is specific enough to build a moat. Also selected by Station F Future 40 2024 — strong peer validation in the French ecosystem.

Sector: AI Agents / Enterprise Sales

14. Linkup — Web Search API for AI

URL: linkup.so

Founded: 2024

Funding: €3M (Seedcamp, Axeleo, Motier Ventures, Nov 2024), then $10M seed led by Gradient (Feb 2026).

Founders: Philippe Mizrahi (CEO, ex-Spotify, ex-Lyft), Denis Charrier (CTO), Boris Toledano (COO, ex-McKinsey).

What they build: Search API for AI applications — legal, ethical, real-time web access to premium content sources. Partnerships with publishers so LLMs can retrieve fresh information without scraping or legal risk. Selected for Microsoft GenAI Studio.

Why it's interesting: The "AI needs fresh data" problem is massive. Linkup is solving both the technical and the legal side simultaneously. Gradient (Google Ventures' early-stage fund) leading the $10M round is a very strong signal. Hundreds of customers including KPMG within the first year of launch.

Sector: AI Infrastructure / Data

15. Kleio — Conversational AI for Sales (Station F 2024)

URL: (kleio.ai)

Founded: 2024

Funding: $3.3M seed.

Founders: Philippe Wellens, Louis Poirier, Adrien Mathieu.

What they build: Conversational AI platform for sales and marketing teams. AI-powered chat that qualifies leads, books meetings, and handles inbound product questions.

Why it's interesting: Very early team, strong seed for a 2024 founding. The conversational lead qualification space is exploding and the French market is underserved.

Sector: AI Agents / Sales

3. Fintech & Financial Infrastructure

16. Lago — Open-Source Usage-Based Billing (YC S21)

URL: getlago.com

Founded: 2021

Funding: $22M total — $7M seed + $15M Series A from YC and FirstMark. 43K+ GitHub stars.

Founders: Anh-Tho Chuong and Raffi Sarkissian, among the earliest employees at Qonto.

What they build: Open-source, self-hostable billing and metering platform. A Stripe Billing alternative for companies with complex usage-based pricing — metering, event tracking, invoicing, tax handling. MIT license.

Why it's interesting: The open-source approach to billing infrastructure is a very smart wedge. Qonto alumni who know the payments stack deeply. Backed by angels from Stripe, HubSpot, and Hugging Face. The GitHub star count (43K) is extraordinary for an infra tool and proves real developer demand.

Sector: Fintech Infrastructure / Developer Tools

17. Formance — Open-Source Payment Infrastructure (YC W22)

URL: formance.com

Founded: 2021

Funding: $30.8M across 5 rounds. Series A from First Round and others.

Founders: Paris-based YC W22 team.

What they build: Open-source, cloud-native financial ledger and money movement infrastructure. Low-code system-of-record for building and managing payment flows, with a programmable ledger at the core.

Why it's interesting: Financial ledgers are a problem every fintech rebuilds from scratch. An open-source, self-hostable alternative with enterprise support is the classic COSS playbook applied to a deeply painful fintech problem.

Sector: Fintech Infrastructure

18. Numeral — Payment Operations API (Hexa Logic Founders)

URL: numeral.io

Founded: 2021

Funding: €13M first round led by Balderton Capital. Largest first VC round ever raised by a fintech in France at the time.

Founders: Edouard Mandon (ex-iBanFirst, Jumia) and Hichem Maalmi (ex-Qonto, Boursorama Banque). Founded at Hexa's Logic Founders studio. Now acquired by Mambu.

What they build: API + web app enabling tech companies to connect to their banks and automate payments from creation to reconciliation. The "plumbing layer" between companies and their banking relationships.

Why it's interesting: Getting Balderton on a first round — 6 months after founding — at that size is exceptional. The Qonto/Boursorama operator background gives serious credibility. Acquired by Mambu (cloud banking) is a validation exit.

Sector: Fintech Infrastructure / B2B SaaS

19. Finary — Personal Finance OS (YC S21)

URL: finary.com

Founded: 2020

Funding: €2.2M seed (Speedinvest, YC, Kima), then $8.9M Series A led by Speedinvest and YC. Total: ~€12M.

Founders: Mounir Laggoune (CEO) and Julien Blancher (CTO). Paris-based.

What they build: Real-time portfolio tracker and personal finance OS for European investors. Aggregates stocks, ETFs, crypto, real estate, private equity — everything in one dashboard. Raised €2.1M from their community in 21 minutes via crowdfunding.

Why it's interesting: The community crowdfunding round in 21 minutes tells you everything about product-market fit. Finary built the product the French personal finance market was missing. Backed by Qonto founders as angels in the Series A.

Sector: Fintech / Consumer Finance

20. Dotfile — Compliance OS for Fintech (Hexa HX21)

URL: dotfile.com

Founded: 2021

Funding: €2.5M seed (Feb 2023, led by V13 Invest + Kima), then €6M (Sept 2024, led by Seaya Ventures + Serena). Total: ~$9M+.

Founders: Vasco Alexandre (CEO) and Titouan Benoit (CTO). Emerged from Hexa (eFounders).

What they build: One-stop orchestration platform for KYC/KYB compliance. Aggregates 40+ identity verification APIs, business registries, AML providers, and fraud prevention tools. Companies mix-and-match providers across 200+ jurisdictions without rebuilding their compliance stack.

Why it's interesting: Every fintech rebuilds this same compliance plumbing. Dotfile abstracts it. Seaya Ventures (Spanish VC, strong EU fintech track record) leading the second round signals pan-European ambitions.

Sector: Fintech / Compliance / Regtech

21. Marble — Fraud & AML Decision Engine (Hexa HX22)

URL: checkmarble.com

Founded: 2022

Funding: Hexa-backed, early seed stage.

Founders: Arnaud Schwartz (CEO). Built from Hexa's fintech studio.

What they build: Next-gen decision engine for fraud and AML compliance. Open-source core that helps fintechs and financial institutions detect suspicious behavior in real time. Replaces rules-based legacy fraud systems with a programmable, auditable engine.

Why it's interesting: Open-sourced their core recently, a bold move. The fraud/AML space is dominated by expensive legacy vendors — a developer-first, open-source approach is a genuine disruption play. Arnaud Schwartz is in the Hexa investor network (invested in Hexa's €20M round).

Sector: Fintech / Security / Compliance

4. Security & Privacy

22. Escape — Offensive API Security (YC W23)

URL: escape.tech

Founded: 2020 (YC W23)

Funding: $3.9M seed (Jun 2023, led by IRIS + Frst + YC), then €15.4M Series A led by Balderton (Mar 2026). 2,000+ security teams globally.

Founders: Tristan Kalos and Antoine Carossio.

What they build: AI-powered offensive security engineering. Dynamic API scanning that discovers, tests, and remediates vulnerabilities directly in the engineering workflow. Replaces legacy scanners and manual penetration testing processes.

Why it's interesting: 2,000+ customers including BetterHelp, PandaDoc, Arkose Labs. Balderton is one of Europe's top-tier VCs — their Series A lead is a strong vote of confidence. The shift from "scan and report" to "AI agents that fix" is genuinely differentiated positioning.

Sector: Security / Developer Tools

23. Qevlar AI — Autonomous SOC Investigations

URL: qevlar.com

Founded: 2023

Funding: €4.5M seed (Nov 2023, EQT Ventures), then $14M seed (2024, EQT + Forgepoint). Series A of €25.8M led by Partech + Forgepoint (Mar 2026). Total: ~$44M.

Founders: Ahmed Achchak (CTO, ex-Natixis ML engineer, ML engineer at Minautor) and Hamza Sayah (CEO, PhD mathematics at EPFL, ex-ETH Zurich spinoff, ex-Ponicode head of research).

What they build: Agentic AI for security operations centers. Automates the investigation and analysis of cybersecurity alerts. SOC analysts spend 80% of time on alert triage — Qevlar does it autonomously, from the alert to the root cause analysis.

Why it's interesting: Angels include Olivier Pomel (Datadog CEO), Mehdi Ghissassi (Google DeepMind), Florian Douetteau (Dataiku CEO). The trajectory — €4.5M to $14M to €25.8M in Series A in under 3 years — is exceptional speed. MATHS + security is a rare combination.

Sector: Security / AI Agents

24. Elba — Employee-Focused Cybersecurity (Hexa HX21)

URL: elba.io

Founded: 2022

Funding: €2.5M seed led by XAnge (Jun 2023). Investors: Kima, Uncorrelated Ventures, Plug and Play, Angel Invest. Angels: Netflix ex-CISO Jason Chan, Sqreen CTO JB Aviat, GitGuardian CTO Eric Fourrier.

Founders: Théo, Grégoire, and Antoine. Previously ran a cybersecurity training company for SMBs before joining Hexa.

What they build: Cybersecurity platform that turns employees into the first line of defense. Detects security issues in apps employees use (Slack, Google Workspace, etc.) and has the employees fix them directly. Netflix pioneered this model internally — Elba productizes it.

Why it's interesting: The Netflix CISO as an investor is an extraordinary signal. Jason Chan literally built the model Elba is productizing. The employee-empowerment angle is a fundamentally different approach from traditional top-down security tools.

Sector: Cybersecurity / SaaS

25. Riot — Cybersecurity Awareness Training (YC S20)

URL: tryriot.com

Founded: 2020

Funding: $3M seed (YC), then $12M Series A led by Base10. Total: $15M+.

Founders: Benjamin Netter (CEO). Paris-based, 150 employees.

What they build: Cybersecurity awareness platform for fast-growing companies. Custom educational content tailored to each team, fake phishing simulations, and culture-building tools. Not compliance checkbox training — actual behavior change.

Why it's interesting: Angels: Snyk's Guy Podjarny, Duolingo's Severin Hacker, Supercell's Ilkka Paananen. Series A at $12M with 150 employees and strong NPS. The human firewall market is massive and underdeveloped in Europe.

Sector: Cybersecurity / HR Tech

26. Sarus — Differential Privacy for Analytics (YC W22)

URL: sarus.tech

Founded: 2020

Funding: €2M seed led by Serena, with XAnge. Total: €3M+.

Founders: Maxime Agostini (CEO, previously co-founded AlephD, acquired by Verizon Media in 2016), Vincent Lepage, and Nicolas Grislain.

What they build: Data infrastructure that lets analysts and ML engineers work on sensitive personal data with mathematical differential privacy guarantees. Zero exposure of raw data, full utility for analytics. Selected by French banking regulator ACPR for a privacy tech sprint alongside Microsoft and EY.

Why it's interesting: Maxime has already exited once (to Verizon Media). The ACPR validation is significant — regulators don't pick random startups for their pilots. Differential privacy is the gold standard and Sarus is the only French company doing it at this depth.

Sector: Security / Data Privacy / Infrastructure

5. Open Source & Compliance

27. Probo — Open-Source Compliance Platform (YC W25)

URL: getprobo.com

Founded: 2024

Funding: YC W25 backed.

Founders: Antoine Bouchardy (certified ISO 27001 auditor) and Bryan Frimin (YC alumnus, previously managed SOC 2 and ISO 27001 at a prior startup). GitHub: github.com/getprobo/probo.

What they build: Open-source alternative to Vanta. Helps startups achieve SOC 2, ISO 27001, and HIPAA compliance in days instead of months. Fully self-hostable, MIT license.

Why it's interesting: Vanta charges $20K+/year. Every startup needs compliance for enterprise sales. An open-source, free-to-start alternative with a genuine compliance expert as founder is a strong wedge. Bryan Frimin has already been through YC — he knows how to execute.

Sector: Open Source / Compliance / Security

28. Twenty — Open-Source CRM (YC S23)

URL: twenty.com

Founded: 2023

Funding: $5M seed led by Runa Capital. Investors include founders of HubSpot, Front, Cal.com, Sentry, and Photoroom.

Founders: Félix Malfait, Charles Bochet, and Thomas Colas des Francs. Félix and Charles sold their previous startup to Airbnb.

What they build: Open-source, self-hostable CRM — the leading open-source alternative to Salesforce and HubSpot. Spreadsheet-simple UX with deeply customizable data model. Active GitHub community since July 2023 launch on Hacker News.

Why it's interesting: Airbnb acquisition in the past is rare pedigree. Getting HubSpot founders as investors for a CRM is a genuine endorsement. The open-source community traction is real — they became the most starred open-source CRM in the world within months of launching.

Sector: Open Source / CRM / B2B SaaS

6. Audio, Video & Creator Tools

29. pyannoteAI — Speaker Intelligence Platform

URL: pyannote.ai

Founded: 2024

Funding: €8M seed (Apr 2025, led by Crane Venture Partners + Serena). Angels: Julien Chaumond (Hugging Face CTO), Alexis Conneau (ex-Meta, ex-OpenAI).

Founders: Hervé Bredin (inventor of the pyannote.audio open-source library) and Vincent Molina. Toulouse-based.

What they build: Language-agnostic Speaker Intelligence Platform. Speaker diarization (who spoke when), speaker identification, voice embeddings. Built on top of the pyannote.audio open-source library which is the de-facto standard for speaker processing, used by Whisper, AssemblyAI, and thousands of developers.

Why it's interesting: Hervé Bredin literally invented the open-source library that the entire industry uses. This is the "open-source project turned company" model at its most direct. The angels are world-class audio/AI names. Crane Venture Partners specializes in deep tech — they know what they're buying.

Sector: Audio AI / Developer Tools

30. Argil — AI Video Creation for Creators (YC S24)

URL: argil.ai

Founded: 2023

Funding: €1M pre-seed (Seedcamp + Axeleo), then €3.9M seed led by EQT Ventures + Kwebbelkop (15M YouTube subscribers) + Charles Gorintin (Mistral AI co-founder). Total: €4.9M.

Founders: Brivael Le Pogam and Laodis Menard. Paris-based, YC S24.

What they build: AI video generation engine for the creator economy. Converts video, text, and audio into multilingual AI-generated avatar videos. Pricing at $1/minute of video. Built for content creators who want to scale output without re-filming.

Why it's interesting: Having a top YouTuber (Kwebbelkop) as an investor is brilliant — he's both a user and a distribution channel. Charles Gorintin from Mistral is a strong technical endorsement. The $1/minute price point is accessible enough to drive real creator adoption.

Sector: Creator Tools / AI Video

31. Photoroom — AI Product Photography (YC W21)

URL: photoroom.com

Founded: 2019

Funding: $19M Series A (Nov 2022), then $43M Series B at $500M valuation (Feb 2024). Total: $64M. 5B images/year, $50M ARR profitably.

Founders: Matthieu Rouif (CEO) and Eliot Andres (CTO). Paris-based.

What they build: AI-powered photo editing app for e-commerce. Remove backgrounds, generate studio-quality product photos, create marketing visuals — all from a phone. 150M+ downloads.

Why it's interesting: This one is slightly bigger than "early-stage" now, but the origin story is pure French indie hacker — built as a side project, launched on App Store, grew to $50M ARR with a tiny team. Proof that a French company can build a truly global consumer product. Balderton-backed.

Sector: Creator Tools / E-commerce / AI

32. Ramdam — AI Creative Intelligence for Brands

URL: (ramdam.io)

Founded: 2023

Funding: $3.2M seed (1 round), led by The Moon Venture, Paris Region Venture Fund, Data Tech Fund.

Founders: Xavier de Baillenx, Emmanuel Lemoine, Benjamin Combes.

What they build: AI-powered creative intelligence platform that helps brands connect with audiences through authentic creator content. Bridges the gap between brand briefs and UGC creator output at scale.

Why it's interesting: The UGC/creator-to-brand gap is real. This is a very French take on the creator economy — focused on authenticity and cultural fit rather than pure volume.

Sector: Creator Economy / Marketing

7. Biotech & Health Tech

33. Raidium — Radiology Foundation Model

URL: raidium.eu

Founded: 2022

Funding: €16M seed (Nov 2024, co-led by Newfund + Kurma Partners + EIC). Also: Galion.exe, Founders Future, Debiopharm, Techmind.

Founders: Dr. Paul Hérent (radiologist) and Pierre Manceron (data scientist). Both former Owkin team members.

What they build: Foundation model for radiology — "GPT of radiology." Training on 1 billion real-world medical images. Builds an AI co-pilot for radiologists that enhances diagnostic efficiency and precision without replacing clinical judgment.

Why it's interesting: A radiologist and a data scientist building together is the ideal founding team for this problem. The Owkin alumni network is credible — Owkin is one of Europe's premier medical AI companies. Station F Future 40 2024. The EIC grant alongside VC means non-dilutive capital stacked on top.

Sector: Biotech / Medical AI

34. Theremia — AI Drug Discovery for Niche Populations

URL: theremia.health

Founded: 2023

Funding: $3.3M seed.

Founders: Chloé Geoffroy (CEO). Station F Future 40 2024.

What they build: AI platform creating drug derivatives optimized for specific population subgroups (children, elderly, rare disease patients). Uses multi-scale algorithms targeting neurological disorders. The core thesis: most drugs are developed for average adult males, then applied to everyone else.

Why it's interesting: This is a genuinely underserved problem. The pharmaceutical industry optimizes for the most common use cases; rare and pediatric medicine is chronically underfunded. Multi-scale AI applied to drug reformulation is technically deep and has real regulatory tailwinds (EU pediatric regulation).

Sector: Biotech / Drug Discovery

35. WhiteLab Genomics — AI for Gene Therapy Design (YC W22)

URL: whitelabgx.com

Founded: 2019

Funding: $10M Series A led by Omnes Capital + Debiopharm (Sept 2022).

Founders: Julien Cottineau and David Delbourgo. Paris-based.

What they build: AI platform for designing gene and cell therapies. Simulates multiple genetic variants simultaneously using ML/deep learning to predict optimal molecular design. Serves biotech and pharma companies across Europe and the US for RNA, DNA, and cell-based therapies.

Why it's interesting: Gene therapy is one of the highest-stakes applications of AI in medicine. YC W22 is unusual for a biotech — YC doesn't take many deep biotech companies. The Debiopharm co-lead (Swiss pharma VC) adds domain-specific validation.

Sector: Biotech / Drug Discovery

36. Entalpic — AI for Catalyst Discovery

URL: entalpic.ai

Founded: 2024

Funding: €8.5M seed led by Breega + Cathay Innovation + Felicis.

Founders: Alexandre Duval (CSO, PhD in ML for materials from CentraleSupélec + Inria, ex-Amazon LLM researcher), Victor Schmidt (CTO, PhD from Mila Institute on ML for climate, ex-UCL), and Mathieu Galtier (CEO, early Owkin employee, former Chief Data & Platform Officer).

What they build: Generative AI platform for designing industrial catalysts. The first target: ammonia production (1% of global CO2 emissions). The platform uses GFlowNet, active learning, GNNs, and LLMs trained on scientific literature to propose catalyst candidates and predict their performance.

Why it's interesting: Three Mila/Owkin researchers backing Yoshua Bengio's scientific advisory board, Thomas Wolf (Hugging Face CSO), and Gilles Wainrib (Owkin co-founder) as advisors. Felicis is a top US fund rarely backing early-stage European companies — they chose this one. The climate angle is real (ammonia production), not greenwashing.

37. Spore.Bio — Next-Gen Microbiological Testing (EF Paris)

URL: (spore.bio)

Founded: 2023

Funding: Backed by Singular. Entrepreneur First Paris portfolio.

Founders: Amine Raji (CEO), Maxime Mistretta (CTO), Mohamed Tazi (COO). Entrepreneur First Paris cohort.

What they build: New generation of microbiological testing technologies for food safety and pharmaceutical quality control. Faster, more accurate pathogen detection than current culture-based methods which take 24–72 hours.

Why it's interesting: Food safety testing is a multi-billion dollar market with essentially zero innovation in decades. EF Paris produces extremely technical co-founding teams — this is exactly the type of deep-science company that cannot be built by generalists.

Sector: Biotech / Food Safety

38. Phagos — Bacteriophage Therapies (EF Paris)

URL: (phagos.com)

Founded: 2021

Funding: Early-stage, EF Paris portfolio.

Founders: Alexandros Pantalis (CEO) and Adèle James (CTO). Both from EF Paris cohort.

What they build: Bacteriophage therapies targeting antibiotic-resistant infections. Phages are viruses that attack bacteria — the original pre-antibiotic approach, now being revived with modern engineering. Target: infections that no antibiotic can treat.

Why it's interesting: Antibiotic resistance is WHO's top global health threat. Bacteriophage therapy is the most promising non-antibiotic alternative. The combination of a biologist (Adèle James) and an engineering CEO is exactly right for the problem.

Sector: Biotech / Infectious Disease

39. Carbonfact — Carbon Management for Fashion (YC S21)

URL: carbonfact.com

Founded: 2021

Funding: $2M seed (YC S21), then $15M Series A led by Alven + Headline. 150+ customers including Columbia, New Balance, Carhartt.

Founders: Marc Laurent (ex-Kerala Ventures, early investor in Doctolib and Malt), Martin Daniel (ex-Airbnb Data Science Lead), Romain Champoulier (ex-JobTeaser CTO).

What they build: Carbon management platform specifically for the fashion and footwear industry. Measures, cuts, and reports emissions. Critical for EU CSRD compliance, which will require 50,000+ companies to report environmental impact by 2025–2026.

Why it's interesting: Three operators with orthogonal but perfect skills: VC instincts, data science, and engineering leadership. CSRD is a massive tailwind — compliance is mandatory, not optional. Growing from 0 to 150 paying brands including major US companies in 18 months is exceptional speed.

Sector: Climate Tech / Fashion / Compliance

40. Firecell — Industrial Private 5G Networks

URL: firecell.io

Founded: 2021

Funding: €6.6M seed (Mar 2024, led by Ventech + Matterwave Ventures + Bpifrance + Bouygues Telecom Initiatives).

Founders: Claude Seyrat, Olivier Dhotel, Cédric Thiénot, and Ulla Saari — former executives from Expway-Enensys and Orange. Nice-based.

What they build: Private 5G network platform for industrial applications. Provides cellular connectivity for factories, warehouses, ports, and campuses — with geolocation and cybersecurity baked in. 75+ customers including SNCF, Airbus, Thales, and the US Army.

Why it's interesting: Getting the US Army and Airbus as customers from Nice is remarkable. Bouygues Telecom as an investor means distribution through a major telecom operator. i-Lab Innovation Competition winner (24th edition) — France's top deeptech award.

Sector: Telecom / Industry 4.0 / Infrastructure

41. HyLight — Hydrogen Airships for Infrastructure Monitoring (YC S23)

URL: hylight.aero

Founded: 2022

Funding: YC S23 backed.

Founders: Thomas, Martin, Théo, and Josef. Based in Plessis-Pâté (near Paris).

What they build: Autonomous hydrogen airships for inspecting energy infrastructure. The HyLighter flies 10 hours at 22mph on hydrogen fuel cells — hybrid airship/drone. Detects methane leaks on pipelines and defects on power lines. 4% of global CO2 emissions come from methane leaks at O&G infrastructure.

Why it's interesting: Hard tech + climate + YC is rare. In their first year: 6 iterations, 150+ flight hours, paid pilots with the largest power line operator in Europe. This is not vaporware — they are flying real airships with paying customers.

Sector: Climate Tech / Hardware / Energy Infrastructure

42. Beyond Aero — Hydrogen-Electric Business Jet (YC S22)

URL: (beyond-aero.com)

Founded: 2020

Funding: $44M+ total. $20M Series A (Oct 2024, co-led by Giant Ventures + Bpifrance). Initialized Capital, Nate Blecharczyk, Arash Ferdowsi as backers.

Founders: YC S22 team. Paris-based.

What they build: Redesigning the CS23 aircraft architecture around hydrogen-electric propulsion. Fuel cell technology, hydrogen tank integration, and advanced cooling systems for a clean business jet. Target: zero-emission short/medium range private aviation.

Why it's interesting: Airbnb's Nate Blecharczyk and Dropbox's Arash Ferdowsi investing in a French hydrogen jet startup is genuinely surprising. Giant Ventures is one of the best climate tech VCs in Europe. The fact that they are redesigning around hydrogen rather than retrofitting a conventional airframe is technically more coherent.

Sector: Climate Tech / Aviation / Hardware

What they build: AI software that enables materials R&D engineers to formulate and analyze new materials much faster. The lab notebook + data management + prediction layer all in one for materials scientists.

Why it's interesting: Two École Polytechnique + Stanford PhDs who worked at Google X (Alphabet's moonshot division) pivoting to deep materials AI. The founding team is exceptional. Collaborative Fund (Tim Ferriss' VC) plus a Sequoia Scout investing signals strong US VC attention on a French company.

Sector: Materials Science / AI / Deep Tech

44. Arago — Light-Based Computing Components (Station F 2024)

URL: (arago.inc)

Founded: 2023

Funding: Early stage, Station F Future 40 2024.

Founders: Researchers from École Polytechnique and MIT.

What they build: Photonic computing components. Light-based computation uses photons instead of electrons, enabling orders-of-magnitude improvements in speed and energy efficiency for AI inference. Building the hardware layer beneath the models.

Why it's interesting: Polytechnique + MIT is about as credentialed as a founding team gets for deep physics hardware. Photonic computing is the most credible path to breaking through the energy/speed wall of silicon AI chips. Very early, very high ceiling.

Sector: Deep Tech / Hardware / AI Infrastructure

45. Altrove — AI Materials Development for Net Zero (Station F 2024)

URL: (altrove.ai)

Founded: 2023

Funding: Early stage, Station F Future 40 2024.

Founders: Not yet public.

What they build: AI-powered materials development platform for discovering Net Zero alternatives. Uses generative AI and simulation to identify new materials that replace carbon-intensive ones in manufacturing, packaging, and construction.

Why it's interesting: Station F Future 40 2024 validated their early traction. The materials-for-Net-Zero space is enormous and underserved by software. This is the Entalpic bet applied to the broader materials market.

Sector: Materials Science / Climate Tech / AI

46. Faircraft — Lab-Grown Leather (EF Paris)

URL: (faircraft.co)

Founded: 2021

Funding: Early-stage, EF Paris portfolio.

Founders: Haïkel Balti (CEO) and Cesar Valencia Gallardo (CTO). Entrepreneur First Paris cohort.

What they build: Lab-grown alternative to animal leather. Biofabrication process that produces genuine leather-like material without slaughterhouses or petrochemical alternatives. Target: luxury fashion houses that need animal-free alternatives without compromising on quality.

Why it's interesting: France is the luxury leather capital of the world. Building lab-grown leather in Paris is strategic — you're adjacent to your first customers (Hermès, LVMH, Kering). EF Paris gives highly technical co-founding teams that generalist accelerators cannot reproduce.

Sector: Biotech / Climate / Fashion

47. Genomines — Phytoremediation Mining (EF Paris)

URL: (genomines.com)

Founded: 2021

Funding: Engine Ventures backing. EF Paris portfolio.

Founders: Fabien Koutchekian (CEO) and Dali Rashid (CTO). Entrepreneur First Paris cohort.

What they build: Plant-based mining technology. Uses hyperaccumulator plants that naturally absorb heavy metals from soil — then harvests those plants to extract the metals. Called phytomining or agromining. Targets nickel, cobalt, lithium — the critical materials for battery supply chains.

Why it's interesting: The EU has a critical minerals dependency problem. Phytomining is the only approach that extracts minerals without open-pit mines. This is either a moonshot or a category-defining company. Engine Ventures (a climate/deep tech fund) is a credible backer for this kind of bet.

Sector: Deep Tech / Mining / Climate

10. B2B SaaS & Business Infrastructure

48. Malibou — French SMB Payroll & HR (YC W24)

URL: (malibou.io)

Founded: 2023

Funding: €3M seed (Breega + YC).

Founders: Maxence Drummond (ex-VC partner at Breega, opened their London office) and Alexandre Pernin (engineer, ex-YC founder in data space, CentraleSupélec + Paris School of Economics).

What they build: First all-in-one payroll and HR software for French startups and SMBs. French payroll is notoriously complex — 800 different labor agreements. Malibou handles employee data, onboarding, leave, payslips, and direct payments in one app, with social law experts on call.

Why it's interesting: Maxence was a VC at Breega before founding — he had access to portfolio companies and saw the problem across dozens of startups. French payroll complexity is a genuine moat. Breega investing in their own ex-partner's startup is a vote of confidence.

Sector: HR Tech / SMB SaaS

49. Kiosk — AI WhatsApp Marketing for E-commerce (YC W24)

URL: (kiosk.app)

Founded: 2023

Funding: YC W24 backed.

Founders: Paul and Thomas. Connected at Hexa studio. Thomas was CTO at Yago.

What they build: AI-powered WhatsApp marketing platform for e-commerce. Personalized chat marketing campaigns, abandoned cart recovery, and customer engagement through WhatsApp — the dominant messaging channel in Europe, LATAM, and MENA.

Why it's interesting: WhatsApp has 2B+ users. E-commerce email open rates are collapsing. WhatsApp marketing is 5x more engaging. The Hexa connection means they understand SaaS go-to-market deeply. YC W24 with a very specific, high-intent vertical.

Sector: Marketing Tech / E-commerce / AI

50. Mindee — Document Understanding API (YC W21)

URL: mindee.com

Founded: 2018

Funding: $14M Series A led by GGV Capital + Alven (Oct 2021). Total: $21M+.

Founders: Jonathan Grandperrin (CEO), Mohamed Biaz (CSO), Olivier Rey (CTO), Victor Briançon-Marjollet (COO). Paris-based.

What they build: Developer API for extracting structured data from documents (invoices, passports, bank statements, receipts). Drop in a document, get back structured JSON. Zero manual data entry. Used by thousands of developers to automate document-heavy workflows.

Why it's interesting: GGV Capital (Alibaba, Airbnb, Slack backer) led the Series A — one of the few French companies to attract top US tier-1 VCs at early stage. The Algolia co-founder and Datadog CTO as angels add strong developer ecosystem validation. François-Guillaume Fernandez (Quack AI founder, above) ran research here.

Sector: Developer Tools / AI / Document Processing

51. Elba (via Hexa) — previously covered; see Security section

52. Slite — AI-Powered Team Knowledge Base (YC W18)

URL: slite.com

Founded: 2017

Funding: $4.4M seed (YC + Index Ventures), then $11M Series A led by Spark Capital (2022). Total: ~$15.5M. $5.5M ARR (2024), 4,000 customers, 40-person team.

Founders: Christophe Pasquier (CEO). Paris-based.

What they build: AI-powered knowledge base and documentation tool for distributed teams. Positioned as the "autopilot knowledge base" — AI surfaces, updates, and verifies company knowledge automatically. Built for remote-first companies.

Why it's interesting: Spark Capital backed Notion, Slack, and Slite — that's meaningful. $5.5M ARR with a 40-person team and 4,000 customers is very efficient. They pivoted hard into AI in 2023 and it's working. This is a team that survives and iterates well.

Sector: B2B SaaS / Knowledge Management

53. Zeliq — AI Sales Stack; see AI Agents section

54. Upflow — B2B Collections Automation (Hexa)

URL: upflow.io

Founded: 2018

Funding: Hexa-backed, Hexa portfolio Scale-stage. Raised €15M Series A led by Alven.

Founders: Alexandre Louisy (CEO) and Barnabé Graveleau. From Hexa studio.

What they build: Customer payment collection tool for B2B companies. Automated dunning sequences, cash flow analytics, payment link integrations. For finance teams tired of chasing unpaid invoices manually.

Why it's interesting: Alven-led Series A for a Hexa portfolio company is a familiar and high-confidence pattern. Cash collection is a universal B2B pain. The Hexa playbook — strong UX, clear buyer, enterprise contracts — is working here.

Sector: Fintech / B2B SaaS

55. Tengo — Public Procurement Winning Platform (Hexa HX23)

URL: (tengo.fr)

Founded: 2023

Funding: Hexa-backed (HX23 batch), early stage.

Founders: Hexa studio team.

What they build: Helps companies win public tenders. AI-powered platform that finds relevant RFPs from government procurement databases and helps companies write competitive bids. Targets the €2 trillion European public procurement market.

Why it's interesting: EU public procurement data is largely open (eu-startups analysis above). Building on top of open government data is a classic underrated moat. Nobody else is doing this well in France. Hexa's operational expertise turns this into an enterprise SaaS play.

Sector: B2B SaaS / GovTech

12. Patterns Worth Noting

The Scaleway alumni network is real. Brainboard's Chafik Belhaoues was CTO at Scaleway. Koyeb's entire founding team came from Scaleway. Two completely different companies, both doing interesting infrastructure work, both originating from the same French cloud company.

The Owkin alumni are seeding deep biotech. Raidium, Entalpic, and others trace their founding teams back to Owkin's AI-for-medicine platform. When France's premier biotech AI company spins out talent, the founders go deep into the same space.

Hexa (eFounders) is still the most reliable factory. Swan, Folk, Numeral, Dotfile, Elba, Marble, Tandem, Upflow — these are all Hexa companies. The studio model keeps producing early-stage companies with strong SaaS DNA, experienced operators, and immediate investor access.

Station F Future 40 is a better filter than most people realize. The 2024 cohort collectively raised €93M with 88% from international investors. dottxt, Raidium, Steerlab, and Entalpic all appeared in these lists before attracting bigger rounds.

The "Polytechnique + Stanford" founding team is a recurring French pattern. Osium AI, Entalpic, and Arago all have founders who went through the French grandes écoles and then did graduate work in the US. This is not a coincidence — the network and training are producing genuinely deep technical founders.

Open source is France's fastest-growing wedge. Lago (43K stars), Twenty, Kestra, Probo, Nango, dottxt (Outlines), Marble, Formance — the number of French companies using open-source as a go-to-market mechanism is striking. The YC and Station F ecosystems have taught founders that GitHub is a distribution channel.
