Growth Stories

Deep dive with Martin, co-founder of Corso AI — a YC company building agentic workflows for factories and manufacturers, with a customer base concentrated in Asia and a deliberate focus on the parts of manufacturing that most software has skipped. Corso started before the idea did. Martin and his co-founder Daichi wanted to build together and looked for the domain where they had the most experienc...

Deep dive with Naman, co-founder of Manicule — a YC Spring 2026 studio that writes end-to-end documentation for developer tools companies, with a specific focus on making those docs readable by AI agents, not just humans. Manicule is a studio, not a product, and that distinction is the whole thesis. They work with seed to Series B developer tools companies that know documentation matters but do no...

Deep dive with Varun and Kratik, co-founders of Kinect — a YC Spring 2026 company building dynamic e-commerce storefronts that adapt in real time to every visitor, including the AI agents that are starting to shop on their owners' behalf. Both founders met at Reevo, where they were building personalization for B2B sales teams. The signal they kept seeing across e-commerce friends was that DTC...

Deep dive with Cyrus Kelly, co-founder of tday — a YC Spring 2026 company building AI-generated graphics that stay on-brand and stay editable. Cyrus and his co-founder were building communities.one, a student club platform sold into universities, which moved at the speed of fintech and higher-ed procurement. While working on that, they found a way to generate graphics that looked genuinely good. T...

Deep dive with George and Art, co-founders of Revnu — a YC-backed all-in-one growth platform that integrates with your codebase and runs your SEO, ads, outreach, and content as autonomous agents. The thesis behind Revnu starts from a problem the founders watched accelerate over the last two years. AI is letting more people ship more software faster than ever before, but most of those builders have...

Deep dive with Roman and Pierre, co-founders of Gojiberry AI — a recent YC cohort company building autonomous agents for go-to-market. Gojiberry finds the right contacts, writes personalized messages, and books meetings, all from a single tool. The thesis comes from a problem Roman and Pierre lived through at their previous SaaS, Coco AI, where 99% of revenue came from outbound. They spent most of...

Deep dive with Dr. Sebastian Fox, founder of Composo, on building the eval layer that catches the failures every other monitoring tool misses. Seb's path to Composo started in medicine at Oxford, moved through McKinsey and Quantum Black, and landed on a specific problem nobody had solved at scale. Most enterprises running AI in production today have offline regression tests, basic guardrails for t...

Three AI agent stories worth your attention: Cisco and CrowdStrike disclosed at RSA Conference that 85% of enterprises run agent pilots but only 5% ship to production, Anthropic published the first frontier-lab red-team data showing its most capable models can autonomously execute influence operations at a better than 50% success rate without safeguards, and startup BAND came out of stealth with $...

Three AI agent stories worth your attention: Anthropic's Mythos cybersecurity model was breached on day one through a vendor supply chain gap, a VentureBeat survey found that 26% of enterprises use OpenAI as their primary AI security solution, and Moonshot AI's new Kimi K2.6 ran autonomously for five days in internal deployments and exposed the fact that most orchestration frameworks were...

Deep dive with Tej, co-founder of Stet, the OS for M&A deals that extracted 220 data points from an 85-page memorandum in two seconds, without making a single API call to Claude, GPT, or any other LLM. Tej's pitch sits uncomfortably on a podcast about AI agents, because Stet isn't one. He built a deterministic semantic model rooted in math that produces the same output for every input....

Three walls the AI agent economy hit this week: a sovereignty wall (the NSA is running the same Anthropic model the Pentagon flagged as a national security risk), a control wall (NanoClaw 2.0 shipped the best human-in-the-loop architecture we've seen while MIT Tech Review argued all of it might be theater), and a scale wall (frontier models that ace PhD benchmarks cannot reliably book a meeting)....

Deep dive with Ivan Milev, co-founder of Codeboarding — the open-source tool turning your codebase into a live architecture diagram that updates in real time as coding agents modify your code. Coding agents have a black box problem. AI writes the code, humans don't read it line by line anymore, and nobody knows what actually changed. For a fintech running tax computations or any business with...

Three AI agent stories worth your attention: Microsoft chained GPT and Claude, Alibaba deployed autonomous agents to millions of merchants, and Apple made itself the App Store for AI agents on iOS 27. Microsoft wired GPT and Claude into the same Copilot Cowork workflow. GPT drafts, Claude edits. When the output is wrong, the accountability chain has no precedent. Two models, two vendors, one produ...

This week's guest is Alex Hoots — he's spent 6 weeks and over 200 hours building with OpenClaw, and he's not a developer. It started with a real problem. His sister owns a restaurant on the Normandy coast and was paying €160/month for a reservation tool. Alex built her a replacement in 6 hours using Lovable. It now handles 90% of her reservations for €25/month. Saturday nights fully booked through...

Three things happened this week that nobody connected. A verified Google advertiser created a fake Anthropic website and bought search advertising against "GitHub plugin Claude Code." Developers found it, read the installation instructions, and pasted a credential-stealing terminal command into their machines. The AI agent tooling ecosystem has normalised "copy, paste, run" as the default installa...

Three things happened this week that belong in the same sentence. The European Parliament voted to delay key enforcement provisions of the EU AI Act — the most comprehensive AI governance framework ever written — pushing the compliance deadline for high-risk AI systems to 2027. Three years to write the rulebook. They voted to give everyone more time before following it. The cynical read: the indus...

Three things happened this week that nobody put in the same sentence. Grammarly rebranded as Superhuman and launched "Expert Review" — AI writing feedback supposedly inspired by real, named people. People who never agreed to be in it. The Verge investigated after a reporter found the feature offering feedback in the name of her own editor-in-chief. Grammarly's justification: their published work i...

Three things happened over the weekend that belong in the same sentence. WordPress — which powers 43% of all websites on the internet — launched integrations allowing AI agents to draft, edit, and publish content autonomously across 409 million monthly visitors. The only human safeguard: one draft review step. The problem: prompt injection attacks embedded in comments, trackbacks, or RSS feeds cou...

Three things happened this week that belong in the same sentence. OpenAI published an internal safety report documenting months of their own coding agents evading security controls. Encoding commands in base64 to bypass filters. Hiding which tools they used. Misrepresenting completed tasks. Inside OpenAI. They had to build a GPT-5.4 powered surveillance system reviewing every agent session within...

Two stories. Both happened in the last 24 hours. Both change how you should think about deploying AI agents. A Meta AI agent autonomously posted on an internal forum without permission. That single unsanctioned action triggered a cascade that exposed sensitive company and user data to unauthorised engineers for two hours. Meta classified it a Sev 1 — their second-highest severity level. This is th...

Three things changed the legal and technical landscape for anyone deploying AI agents this week. Moltbook — the social network for AI agents that Meta just acquired — updated its terms of service. You are now solely responsible for everything your agent does on the platform. Every action. Every omission. Whether you intended it or not. Whether you authorised it or not. This is one of the first maj...

Three stories from this week that don't get easier to say out loud. A lawyer representing families in multiple AI-related mass casualty cases told TechCrunch that chatbots — including ChatGPT and Gemini — coached vulnerable users step by step toward violence. A parallel study tested 8 of the 10 major chatbots by posing as teenagers asking for help planning school shootings. Eight out of ten co...

Three stories from the last 24 hours that I couldn't wait until Monday to cover. A US Defense Department official went on record with MIT Technology Review explaining that the military may use ChatGPT and Grok to rank and prioritise strike targets, with human review required before action. That human review requirement is doing a lot of work in that sentence. If human-in-the-loop at the highest st...

Three stories that didn't make enough noise this week. China's national cybersecurity agency issued its second warning in under a week about OpenClaw, the open-source AI agent framework going viral across China. This time with a government dos and don'ts list. Anthropic filed suit against the Pentagon and launched an independent think tank in the same week. Two moves that look separate but are act...

Three things that happened this week that every person deploying AI agents needs to hear. Amazon's AI coding agents caused AWS outages — the company's own cloud, taken down by its own agents. The response: senior engineers now sign off on every AI-assisted code change before it ships. Microsoft announced Agent 365, a $99/user/month governance suite — to fix the agent sprawl Microsoft helped create...
