Hey everybody, welcome back to Product Market Fit 🚀🚀

Last week, while putting together the YC F25 “Requests for Startups,” one line stuck with me: the call for “the first 10-person, $100B company.”

YC believes small, high-agency teams, even solo founders, can build multi-billion dollar companies.

That had me thinking about solo founders all week, so I revisited Lenny’s episode with Base44’s founder Maor Shlomo.

Six months. One founder. An $80M acquisition by Wix.

Base44 is an AI app builder that lets anyone describe an idea in plain language and get a working full-stack app, part of the fast-rising “vibe coding” wave where prompting replaces most hand-coding.

Maor Shlomo bootstrapped the company, stayed profitable, and grew to hundreds of thousands of users with a tiny team before selling it to Wix in June.

What’s inside today’s newsletter:
