New Ramp data says 80% of OpenAI and Anthropic's enterprise revenue comes from 1% of their customers, a concentration risk unseen in any other software category. Eric and Neil dig into what that means for the AI trade and for every company betting on it. Then Tomasz Tunguz's five-year writing data: AI didn't reduce his editing, it raised the quality floor, and the weakest posts gained twice as much as the strongest. Plus ICONIQ's headcount report (the 100%+ growers added 133% more headcount while the 50-100% band cut hiring almost in half), YC's product-market-fit data on user conversations, and a detour into foldable phones.

Key takeaways◾1% of customers drive 80% of OpenAI and Anthropic's enterprise revenue. That's the risk◾AI raises the floor of your work, it doesn't shrink the effort◾10+ user conversations a week is the most predictive variable for finding PMF
