Deleting the Product and Doing the Thing

Roman Ugarte helped incubate and build Grok Bot, the popular new knowledge-work agent from SpaceXAI. A small, isolated team took it from first line of code to a working internal product in four weeks, and to a hugely successful public launch just three weeks later. Before Grok Bot, Roman led Growth at Cursor, where he helped scale the company from 15 people to over 1,000 before its acquisition by SpaceX.

In our in-depth conversation, we discuss:

1. The origin story of Grok Bot

2. The key decision to build it from scratch instead of adding it to Cursor

3. Why the team personally onboarded nearly 300 of its first users

4. The two early product decisions that made Grok Bot so successful

5. Their “colleague-pilled” product philosophy

6. Roman’s advice on moats, and what has allowed Cursor to keep winning in the most competitive market in the world
