🧵 Yesterday we made the difficult decision to stop serving traditional small businesses at Brex. Brex remains deeply committed to serving startups, so let me explain how we got to this (painful) decision, and why it allows us to serve startups even better.

If a company’s moat wasn’t taken down or eroded during ZIRP, that’s a pretty good sign of a durable competitive advantage.

Years of working in Uber’s payments team changed my view on distributed systems where participants can make money. I don’t believe any such distributed system can be as efficient as a centralised one. A centralised system spends SO much on fraud reduction and customer support.

Nvidia keeps crushing because Jensen runs it unlike other CEOs: - No 1:1s - No 1 or 5-year plans - No status reports - 60 direct reports Once you see why he does it, you can't unsee it And it explains everything wrong with the traditional way of running a company🧵

Recently realized LLMs work better with positive reinforcement and negativity makes them spiral into confusion. Now here I am responding “it’s okay Claude that was a tricky mistake but I believe in you, you can do it!”

Game changer for using Claude Code: “Write e2e tests for all the user flows you’ve touched on and iterate until all issues are resolved”

How much of vibe coding’s appeal is the gamble (will it work?) vs real productivity gain?👀

America’s social issues won’t resolve until they stop being a finger pointing game. Feels like no one really wants resolution, just want to point out hypocrisy of the other side.

This would be a hilariously incapable LLM, kinda wanna see it
