Why come
One stage, no juggling rooms
Builder's Day is a single-track, one-day AI developer conference in San Francisco. One stage, no juggling rooms, and a lineup of engineers, founders, and product builders who are shaping how we build with AI and excited to share what they've learned.
The talks come from builders deep in the weeds with AI agents, and from the people at the companies building the tools they rely on. You'll hear both how it's being built and how it's holding up in production.
Learn
Talks and demos on AI engineering: coding agents, LLM applications, and the infrastructure behind them. Hear the techniques, the failures, and what actually works in production.
Network
Spend the day with engineers, founders, and product folks who are building with AI right now, not just talking about it.
Share
Trade notes with other builders over ping pong and drinks. Some of the best ideas come out of a hallway conversation.
The day

Doors open at 8:30 AM and the day runs through talks, lightning rounds, and an afterparty. We're locking in speakers and sessions now, and the full lineup will be announced soon.
