Builder is a monthly gathering for people who like to build — devs, designers, PMs, founders, and AI-curious. We explore the tools and systems shaping AI today, from models to infrastructure to agents, with an emphasis on privacy, open-source, and decentralization.

Each month centers on a different theme, with guest speakers sharing short talks, technical deep dives, and live demos of what they're working on. Expect plenty of time for Q&A and open discussions.

Our hope is that you leave each meetup having learned something new, met someone interesting, and gained a little more confidence to ship what you're building.

We meet on the 4th Thursday at a community workspace in the Presidio of San Francisco.
