Exa just made our first acquisition: Browser Buddy @trillarnie and @jeremyjsuh were working on new types of retrieval to organize the web, so that anyone could find the best blogs and essays. Now they’re joining Exa to do the same, but for all the world’s information. They’re two of the smartest and kindest engineers I’ve met, and it’s already been an insane few days working with them. Here’s to organizing the web together 🍻

Anthropic just mass-licensed 10,000 of the most influential developers in the world for $12 per person per month. The math: 10,000 maintainers × $200/month × 6 months = $12M in sticker price. Actual compute cost to serve these accounts runs closer to $30-50/month each, meaning the real spend lands around $3-5M total. Those 10,000 people maintain an open source ecosystem valued at $8.8 trillion in demand-side impact, according to Harvard and the Linux Foundation. 60% of them are currently unpaid. This tells you everything about how Anthropic views developer distribution. They’re acquiring the people who decide what tools get baked into every CLAUDE.md file, every CI/CD pipeline, every GitHub Action, and every project README across the most-used repositories on the planet. And they’re doing it for the cost of a Series A marketing budget. Think about what happens when a maintainer of a 5,000+ star repo starts using Claude Code daily. They write CLAUDE.md files. They add Claude Code GitHub Actions. They reference Claude in contributor docs. They build workflows that assume Claude as infrastructure. Every contributor to that project encounters Claude as the default. 10,000 maintainers each influence, conservatively, 50-100 downstream developers through their projects. That’s 500K to 1M developers seeing Claude Code embedded in their daily workflow within six months. GitHub spent years and hundreds of millions building Copilot awareness through traditional developer marketing. Anthropic is spending $3-5M in compute to get Claude Code embedded at the infrastructure layer of open source itself. The timing is surgical. Microsoft killed Azure Sponsored Subscriptions for open source maintainers in September 2025. Burnout rates among maintainers hit 44%. Quit rates hover at 60%. Anthropic walks in with the most expensive AI subscription on the market, handed out free, right as everyone else retreats. The selection criteria reveal the strategy. 5,000+ GitHub stars or 1M+ monthly NPM downloads. These are the people whose tooling decisions cascade through dependency trees touching every Fortune 500 codebase. $3-5M in compute for 500K-1M developers organically adopting your tool through the open source dependency graph. That’s $3-10 per developer acquired, embedded at the infrastructure layer where switching costs compound monthly.



Out now: press.stripe.com/maintenance-pa… @stewartbrand's Maintenance: Of Everything, Part One—about the continuous repair work that keeps complex systems intact, spanning stories from a round-the-world sailboat race, to the restoration of the Statue of Liberty, to the Model T’s rise.

Do the people using the formula "X isn't just Y, it's Z" every other sentence realize that everybody else can see where this is coming from
