The Holiday Science Fair (Hot Cocoa, Cookies, and Demos!)
Ring out the year with one last night of demos, food, and friends.
We’re closing out 2025 at Foundations. Help yourself to hot cocoa and warm cookies, gather round the demo stations, and stay a while!

What is AI Tinkerers?
AI Tinkerers is the world’s most curated community of active AI builders: engineers, researchers, founders, and technologists who come together to share real work and push boundaries. Selective by design, entry is earned, not granted. We focus on hands-on innovation, not theoretical pontification. Every event delivers working code, live demos, and systems in motion.
If you are actively building with AI, have hands-on experience deploying these systems, and want to trade notes with peers, this is the room for you. Space is limited, so register early.
The Science Fair: Demos First
This event is built around the demo. We encourage messy experiments, creative hacks, and technical discoveries in action. Your presentation must answer: “How did you build this interesting thing?” Working code or nothing.
All approved demos will participate in the Science Fair, setting up hands-on stations for deep-dive Q&A and peer review. Two or three demos will be selected for the Mainstage.
- Mainstage Demos: Capped at 5 minutes.
- Science Fair Stations: Capped at approximately 30 minutes per cycle. This is for hands-on technical Q&A at your station. Bring your laptop and be ready to pop the hood on your stack.
