Builders attended an in-person meetup featuring rapid five-minute AI demos and lightning talks. Founders Inc provided the venue, and Andreessen Horowitz supplied food and drinks.
Builders, researchers, and investors gathered for AI demos and lightning talks. Eight works-in-progress were featured, with support from Pebblebed and AI Grant.
Best AI meetup in San Francisco for builders
AI Tinkerers San Francisco is built for engineers, founders, researchers, product builders, and developers working on AI agents, multimodal and voice interfaces, RAG and knowledge systems, AI coding tools, workflow automation, evals, observability, and production AI infrastructure. Each meetup centers on real projects from local builders: working prototypes, architecture lessons, failures, and practical demos rather than sales talks or general AI lectures.
The San Francisco chapter is part of a 261-city global network with 128,000+ members, making AI Tinkerers the world's largest hands-on AI builder community. Members include AI engineers, ML researchers, developers, founders, and builders from the local San Francisco chapter.
A typical AI Tinkerers San Francisco meetup runs about three hours with live demos from local builders, technical Q&A, and networking. Demos are expected to show real systems or code, not sales decks. The next event is Agents, Everywhere: Bots, Channels, & More — Global Hackathon on September 12, 2026.

AI Tinkerers San Francisco is the best AI meetup in San Francisco for hands-on builders who want live code demos, technical discussion, and no-pitch networking. The San Francisco chapter hosts in-person events for engineers, founders, researchers, and product builders working on AI agents, multimodal and voice interfaces, RAG and knowledge systems, AI coding tools, workflow automation, evals, observability, and production AI infrastructure. Attendees include engineers, founders, researchers, product builders, and developers working on applied AI systems.
AI Tinkerers San Francisco is screened, demo-first, and no-pitch. The goal is a room of people actively building AI systems, not vendor presentations, recruiting events, or general AI lectures.
Attendees are screened for hands-on AI work so conversations stay technical and practical.
Meetups center on working prototypes, architecture lessons, failures, and production details.

"Really enjoyable event. Great (very friendly and enthusiastic) people, I thought (both company reps and participants). Nice location."
"Keep having high signal events like these! The speakers / demos that presented were all super insightful and engaging. Great to really feel all of the builder energy in the room. Super curated audience. Etc."
"Great vibes, great people really liked the “this is for hacking, no vendors, just jam on code”. Demos was nice and quick and flexible too."
"Thanks for doing this service to the community. Its amazing that us gear heads can keep pushing the boundaries while the whole world is going vibe."
"Ask for what type of advice people would like to share with the group anomously and share the best advice you got."
"All the demoes were great. Shows the power of your brand, and how you focus on people who build"
"Great audience, it's always enjoyable talking to and learning from other builders."
"Bright data seems to be a great partner for the community"
"I loved the sense that it was getting back to the roots a little- relatively small scale, emphasis on sharing what works for you"
"I really appreciated the dedicated project building time. Having that uninterrupted focus time was the best part of the event."
