Roman Ugarte, who leads product for Grok Bot at SpaceXAI, tells Lenny Rachitsky how a small, isolated team built Grok Bot from scratch in one month and launched it publicly just three weeks later. He explains why they built it separately instead of inside Cursor and why the team manually onboarded 200–300 users, including a coffee shop owner, to check blind spots. Two early decisions made it work, he argues: giving every bot its own cloud computer instead of sharing yours, and a 'colleague-pilled' philosophy that hides internal mechanics so delegating feels like trusting a real teammate. He also covers unshipping features pre-launch, natural-language automations, and argues Cursor outlasted OpenAI and Anthropic by reinventing itself every six months—moats are discovered, not planned.
