Hackathons
Event reports: the arena, the constraint, what shipped under pressure, the result, and what carried forward into the product.
"Build an Agent" Hackathon
submittedBuilt Corgi Ads with Zen in three and a half hours. An ad agent you talk to. It studies competitor ads, makes the creative, stages it on Meta and proposes where the money should go. You approve; it acts.
JEVathon, TypeSafe AI × AI Collective
submittedBuilt JEVgotiator with Chris and Dara in a three-hour window. Text an agent the Tesla you want. Code applies the hard limits, Jev scores up to 30 candidates, and you get five picks and a plan for the deal.
AI Tinkerers Agents Everywhere

2026 AI Engineer World's Fair Hackathon
submittedBuilt reSKILL solo at the AI Engineer World's Fair, a sealed replay gate for self-improving agents. A skill rewrite gets promoted only if it fixes the target failures without breaking a single held-out case.
OpenAI Voice Hack Night, Cerebral Valley
