INVITATION ONLY

Join the invite list

Builders Day is a closed-door room of senior engineers, technical founders, and operators. Tell us a little about you and we'll be in touch as the next editions take shape.

What to expect

  • Closed-door panels, spotlights, and firesides — Chatham House style.
  • 200+ senior builders across frontier AI, inference, and physical AI.
  • New York every spring. San Francisco every summer.
  • Applications are reviewed personally; attendance is limited.

We only use this to review your application. No lists, no spam.
