Companies Building Cool Shit in SEO and AI Mentions
SEO is not dying; it is splitting in two. The old job is still there: rank on Google for queries that matter, get clicks, convert. The new job is brand new: get cited by ChatGPT, show up in Google AI Overviews, be the source Perplexity recommends when someone asks a question in natural language. That second job has a name now. Some people call it GEO (Generative Engine Optimization); others call it AEO (Answer Engine Optimization); others just call it "AI visibility". The name war is not settled yet.
What is settled: a full stack of companies is being funded to solve this. Sequoia wrote a $35M check into Profound, then Profound raised another $96M in February 2026. NEA wrote a $20M Series A into Bluefish. Singular led a $21M round into Peec AI in Berlin. Y Combinator backed AthenaHQ. Ahrefs and Semrush both retooled their flagship products around AI visibility in the last six months. And a whole tier of scrappy indie tools is selling $29 to €49 subscriptions to solo founders who want their product mentioned by Claude.
This page is a tour of the companies actually building in this space in April 2026. Grouped by tier and posture. What they do, who funds them, what makes each one interesting.
Why this space exists
For twenty years, SEO meant one thing: rank in Google's ten blue links. Keyword research, backlinks, Core Web Vitals, schema markup, content clusters. A mature craft with mature tools: Ahrefs, Semrush, Moz, Screaming Frog, Surfer, Clearscope. Marketers knew the playbook.
Then ChatGPT happened. Then Perplexity. Then Google started showing AI Overviews above the blue links. Then Claude started browsing. Then Copilot. Then Gemini. Suddenly a bunch of queries that used to drive traffic to a website now get answered by an LLM quoting that website instead. No click, no session, no ad impression. Just a citation in a generated paragraph.
This is a real problem. Brands are watching their organic traffic flatten or drop, while their "mentions in ChatGPT" become the thing that actually drives awareness. Nobody has tooling for it. You cannot open Google Search Console and see "your brand was mentioned 4,312 times by Claude this week". You cannot A/B test whether adding a FAQ block makes Perplexity more likely to cite you. So a whole category of tools had to be invented, and a whole category of VCs suddenly had a thesis: whoever owns the measurement layer for AI search owns a Salesforce-sized market.
That is the pitch. Now to the companies.
The enterprise war: Profound, Bluefish, Peec AI
Profound
Profound is the clear market leader by capital raised. New York City, founded by cofounders who met at South Park Commons, launched in 2024, and less than a year after launch it was signing Fortune 10 clients. Sequoia Capital led its $35M Series B in August 2025, with Kleiner Perkins, Khosla Ventures, Saga VC, and South Park Commons continuing on. Then in February 2026, Fortune reported another $96M raise. Total funding is now north of $150M, which is absurd for a company this young.
What they do: monitor brand visibility across ChatGPT, Perplexity, Google AI Overviews, Copilot, and Claude. Track which prompts include your brand, which competitors get cited in the same queries, and what content sources the LLMs are pulling from. Profound sends this to Fortune 500 CMOs with dedicated "AI strategists" attached as white glove support. 2,000 marketers across 500 organizations use it daily.
Why it is interesting: Profound is betting hard on being the enterprise-grade, category-defining vendor; the "Salesforce of AI search" line is literally what Sequoia wrote in their partnership post. The product is not the moat. The relationships with CMOs, the Fortune 500 logos, the velocity of shipping, and the category ownership are the moat. If this category calcifies the way martech did, Profound is trying to be the Salesforce before anyone else even finishes building their Siebel.
Bluefish AI
Bluefish is the direct answer to Profound from a slightly different angle. NYC based, $20M Series A led by NEA in August 2025 (total funding $24M in twelve months). Salesforce Ventures, Crane Venture Partners, Swift Ventures, Bloomberg Beta on the cap table. The team is the kicker: the founders previously built PromoteIQ (acquired by Microsoft) and LiveRail (acquired by Facebook), so this is their third rodeo in the "help big brands measure attention in a new channel" playbook.
What they do: track, optimize, and measure how enterprise brands show up in AI chat queries. Adidas is a public customer; Tishman Speyer is another. They claim 10x revenue growth in six months. The interesting part of their pitch is the optimization layer: Bluefish will tell you the exact content change that would make ChatGPT mention you more favorably, and then push that change into your CMS. Closer to an ad platform than a dashboard.
Why it is interesting: Bluefish is betting that enterprise marketers will pay for a platform that goes beyond observability into action. If Profound is the Salesforce, Bluefish is trying to be the paid acquisition tool. Same customer, different part of the workflow.
Peec AI
The European answer to Profound and Bluefish. Berlin based, raised €5.2M seed, then $21M Series A led by Singular with Antler, Combination VC, identity.vc, and S20 participating. Total funding around $29M. Hit $4M ARR ten months after launch, which is Profound-tier velocity at a fraction of the capital.
What they do: track visibility across ten AI engines (ChatGPT, Perplexity, Gemini, Microsoft Copilot, Google AI Mode, AI Overviews, Claude, Grok, DeepSeek, Llama). The coverage is wider than anyone else; ten engines is more than Profound or Bluefish list publicly. Dashboards for share of voice, competitor tracking, and prompt-level attribution.
Why it is interesting: Peec AI proves this category does not have to be an American monopoly. European buyers want a European vendor (privacy, procurement, GDPR alignment), and Peec is eating that market at speed. They are also the go-to "alternative to Profound" recommendation in comparison posts, which suggests product is keeping pace with the marketing.
The incumbent pivot: Ahrefs, Semrush, SE Ranking
The established SEO platforms had a choice when the AI mentions problem appeared: ignore it, bolt on a feature, or rebuild the flagship product around it. All three decided the answer was "rebuild the flagship".
Ahrefs Brand Radar
Ahrefs launched Brand Radar as a standalone tool sitting next to Site Explorer. It covers six AI platforms (ChatGPT, Perplexity, Gemini, Copilot, Google AI Overviews, Google AI Mode) plus YouTube, TikTok, and Reddit mentions. In January 2026 they added custom prompt tracking, which lets paid users track specific queries instead of relying on the native index of 243M monthly prompts scraped from real People Also Ask data.
Pricing is aggressive in the other direction: $199 per month per AI index, or $699 per month for all six bundled, on top of the base Ahrefs subscription starting at $129. Full AI coverage can push past $1,100 per month. The pricing is clearly aimed at enterprise teams that were already Ahrefs customers and will absorb the line item without pushback.
Why it is interesting: Ahrefs is using its existing index as an unfair advantage. Nobody else has 243M real search prompts to sample from. If the category turns into a data arms race, Ahrefs already has the data.
Semrush One
Semrush went further than Ahrefs: they rebranded their flagship. Semrush One launched in October 2025 as a unified SEO + AI Visibility platform, merging the 55+ tool SEO Toolkit with the new AI Visibility Toolkit that tracks 100M+ LLM prompts globally (including the largest public U.S. database of 90M+ prompts and a ChatGPT-specific database of 29M+ prompts). Coverage: ChatGPT, Google AI Overviews, Perplexity, Gemini.
Why it is interesting: Semrush is the only incumbent that moved the whole product, not a sidecar. Semrush One is a bet that "SEO" and "AI visibility" stop being separate categories within eighteen months, and whoever owns the unified dashboard wins the next decade of marketing budget.
SE Ranking AI Results Tracker
The third incumbent play. SE Ranking added daily brand mention tracking across Google AI Overviews, Google AI Mode, ChatGPT, Gemini, and Perplexity, with 188 country coverage. Less marketing noise than Ahrefs or Semrush, but the feature set is solid and they ship updates weekly. SE Ranking is positioning as the "cheaper Semrush", and the AI tracking extension keeps that positioning intact.
The YC wave: AthenaHQ, Relixir, Daydream
AthenaHQ
YC backed. Founded by Andrew Yan and Alan Yao, both ex-Google Search / DeepMind. Raised $2.2M from YC and notable SEO industry angels. AthenaHQ positions itself across all three acronyms (SEO, GEO, AEO) and tracks brand appearance in ChatGPT, Perplexity, Claude, Gemini, and others.
Why it is interesting: the founder pedigree is the hook. If anyone should know how LLMs rank and cite sources, it is the people who used to build the search side at Google and DeepMind. AthenaHQ is the "technical founder" play in a category otherwise dominated by ex-adtech operators. They are also the clearest YC-branded option in a space where most tools are bootstrapped or VC-direct.
Relixir
Another YC backed GEO tool. Founders Sean Dorje and Dennis Zax originally built a local SEO content automation tool; when they saw traffic shifting from Google to LLMs, they pivoted the engine into Relixir. The tagline is direct: "ChatGPT mentions to direct revenue". Relixir auto-generates, updates, and distributes brand-aligned content optimized to rank in generative search.
Why it is interesting: Relixir is one of the few tools that closes the loop. Most GEO platforms tell you what is happening in AI search; Relixir will actually write and publish content optimized to change the answer. This is closer to Jasper-plus-Profound than pure analytics.
daydream
Not exactly a pure product; daydream is an "AI-native agency" for SEO, raised $15M Series A in April 2026 led by WndrCo with First Round Capital and Basis Set Ventures. Total funding $21M. They combine SEO agents with human experts to deliver full-service search support across both traditional Google SEO and AI search (ChatGPT, Perplexity, Gemini).
Why it is interesting: daydream is the bet that the agency model, not the pure-software model, wins this category. YC's own Request for Startups in Spring 2026 ranked AI-native agencies at #3 in the categories it wants to fund. If SEO work turns out to be more "services augmented by agents" than "software replacing services", daydream is the archetype.
Content first plays: Writesonic, Goodie, AirOps
A third posture in this market: start with content generation, add visibility tracking later. These companies were already shipping AI writing tools; they bolted GEO onto the side because their customers were asking.
Writesonic
Writesonic rebuilt itself around GEO in late 2025. The platform tracks brand mentions across ChatGPT, Gemini, Claude, and Perplexity, then routes insights into an "Action Center" that turns visibility gaps into step-by-step content workflows. A built-in AI writer produces articles tuned for LLM citation rates. Pricing from $199 per month.
Why it is interesting: Writesonic is the only content-first tool that fully closed the loop from "detect the gap" to "write the piece that fills it". The Action Center is the kind of workflow that would cost $1,500 per month at Goodie AI or Profound.
Goodie AI
Goodie is an end-to-end AEO platform built by NoGood, a New York growth agency. It bundles AI content creation, cross-platform LLM tracking (ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews), and competitive intelligence dashboards. $495 per month starting plan, enterprise pricing on request.
Why it is interesting: Goodie is the agency-to-product play. NoGood had the expertise (they run GEO audits for big brands already), and they productized the internal tooling. Higher price than Writesonic, but closer to the services / agency budget line than to the software budget line.
AirOps
AirOps is the "workflow builder for content" that pivoted hard into GEO. AI search visibility tracking across ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode, plus a visual workflow builder and direct publishing to 7+ CMS platforms (WordPress, Webflow, Contentful, and more).
Why it is interesting: AirOps is the only tool in this list where "AI visibility" is the entry point and "content automation at scale" is the destination. You can build a loop where the tracker detects a gap, a workflow generates a draft, and the CMS publishes it. That is operationally what enterprise content teams are trying to stitch together manually today.
The indie tier: Otterly, Rankshift, RankBee, Mangools, Scrunch, Gauge
Below the VC-funded tier sits a whole layer of scrappy, mostly-bootstrapped tools that sell directly to solo founders, small agencies, and indie marketers. Prices from $29 to $300 per month. Shorter feature lists, faster iteration, friendlier onboarding.
Otterly AI
Austria based, the cheapest entry point in the market. Starts at $29 per month for 10 search prompts. Tracks brand mentions on Google AI Overviews, ChatGPT, Perplexity, Google AI Mode, Gemini, and Copilot. No frills, no dedicated strategist, no enterprise contract; just a dashboard that answers "am I getting mentioned". Ideal for a side project that cannot justify Profound.
Rankshift
Credit based pricing from €49 per month for 5,000 credits, pay only for what you use, unlimited users and projects. Tracks ChatGPT, Perplexity, Claude, Gemini with share of voice and historical trends. 30 day free trial. Rankshift is the clearest "no subscription trap" option in the category; the credit model lets you spin it up for a campaign and let it idle otherwise.
RankBee
RankBee was launched by Aris, a second-time founder with 25+ years of product and marketing leadership, including running SEO for Amazon and Orbitz Worldwide. Tracks brand representation across ChatGPT, Gemini, Claude, and others. The pedigree is the pitch: whoever ran SEO for Amazon probably has an opinion about how to rank in AI search.
Mangools AI Search Watcher and AI Search Grader
Mangools (the KWFinder team) split their AI offering into two. AI Search Grader is a free one-shot audit: paste your domain, get a GEO score across ChatGPT, Perplexity Sonar, DeepSeek V3, and Claude. AI Search Watcher is the paid continuous monitoring version. The free grader is genuinely useful as a lead magnet and as a due diligence tool for founders evaluating the category.
Scrunch AI
$300 per month, no free trial, and a narrower scope than the rest of the list: Scrunch is positioned around brand safety and misinformation monitoring on top of AI visibility tracking. Does not currently cover Google AI Mode or Copilot. If your concern is "what bad thing is ChatGPT saying about my brand" rather than "how often am I cited", Scrunch is the specialist.
Gauge
Gauge positions as an "end to end AI marketing agent", one of the first tools in this list pitching itself as an agent rather than a dashboard. Category observers ranked it #1 in end-to-end tooling in their 2026 reviews. Smaller footprint than Profound or Bluefish, but the agent framing is where the category is probably headed.
What is actually cool
Seven observations after looking at all of this:
1. The index is the moat. Every dashboard looks roughly the same; the difference is how many prompts each tool can sample. Ahrefs has 243M real prompts. Semrush has 100M+. Profound and Bluefish are scraping and synthesizing continuously. The companies with data arbitrage win.
2. Incumbents moved fast, not slow. Everyone expected Ahrefs and Semrush to be the Kodak of AI search. They were not. Ahrefs shipped Brand Radar and custom prompt tracking within months. Semrush literally rebranded their flagship to Semrush One. This is the fastest pivot any established SEO tool has ever made.
3. Enterprise is the prize, but indie is the volume. Profound and Bluefish are going for ten-logo-a-quarter Fortune 500 sales. Peec AI, Rankshift, Otterly, and Mangools are going for the long tail of agencies and founders. The ARPU gap is 100x but the customer count gap might be 10,000x. Both posture can work.
4. Observability plus action is the upgrade path. Every dashboard-only tool is going to get compressed. The tools that survive will either do optimization automatically (Relixir, Writesonic, Goodie, AirOps) or push deep into a specific persona (Scrunch on brand safety, RankBee on ecom/travel).
5. Agents are the next posture. Gauge and daydream both frame themselves around agents, not dashboards. This is where the category is heading: not "here is your visibility score" but "here is the plan and here is the content we just shipped to move the score".
6. European vendors can win this. Peec AI from Berlin raised at the same velocity as NYC startups. Otterly from Austria owns the low end. Rankshift prices in euros. GDPR and procurement still matter in EU enterprise sales, and a vendor who can sign a DPA on day one has a real edge.
7. Nobody has solved attribution yet. Every tool can tell you "you were mentioned". None can reliably tell you "that mention drove $X in revenue". The company that solves citation-to-revenue attribution will eat a lot of the category.
What is still missing
Holes in this market that nobody has filled yet. Each of these is a reasonable startup pitch for a solo founder or a small team.
A source-side tool for publishers. Every GEO tool sells to the brand trying to get cited. Nobody sells to the publisher trying to stay in the source list. WordPress plugins, site audit tools, and Cloudflare integrations for "are you still being crawled and cited by LLMs?" would be a real product.
A language-specific GEO tool. All the big tools are English-first, maybe with French / German / Spanish bolted on. A vertical tool for Japanese, Arabic, or Portuguese markets would have zero direct competition and a real audience of local SEO agencies.
A free / open source GEO tracker. Plausible did this for analytics. Umami did this for site stats. Nobody has done it for AI visibility. A self hostable tracker that samples ChatGPT, Claude, and Perplexity daily and writes the results to a Postgres table would find an audience in ten minutes on Hacker News.
A vertical GEO tool for one job category. GEO for law firms. GEO for medical practices. GEO for SaaS. Profound is going horizontal; the vertical wedge is wide open. Paperclip-for-churches energy applied to AI visibility.
The citation to revenue attribution platform. Still unsolved. Probably needs a browser extension, a UTM-style parameter convention, or a deal with the LLM vendors themselves. Whoever ships this eats the category.
The short version: GEO / AI visibility is the fastest-moving category in marketing software right now. Three enterprise players already raised nine figures between them; two incumbents rebuilt their flagship products; a YC wave of technical founders is shipping from below; and an indie tier is selling $29 subscriptions while the big guys price at $1,000+. The category is not settled and probably will not be for another year. If you are building in SEO, AI, or martech, this is the most interesting place on the map in April 2026.
