Michael Truell: How Cursor Builds at the Speed of AI
When four MIT grads decided to build a code editor while everyone else was building AI agents, they created the fastest-growing developer tool ever built.
Cursor CEO Michael Truell joins a16z’s Martin Casado to discuss the deliberate constraints that led to breakthroughs: why they rejected the "democratization" narrative to focus on power users, how their 2-day work trials test for agency over credentials, and the strategic decision to own the editor when conventional wisdom said it was impossible.
