​AIxBio Hackathon 2026 - San Francisco

​Build tools for biosecurity before biology outpaces safety. Join 500+ participants globally for a weekend tackling DNA synthesis screening, pandemic early warning, and AI biosecurity tools.

​The Event

​AI is transforming biology faster than biosecurity can keep up. Open-weight biological foundation models and benchtop DNA synthesizers are making it possible to design novel biological sequences with less expertise than ever. Current screening infrastructure covers only a fraction of global synthesis capacity, and most defensive tools are siloed, under-resourced, or still in the research phase.

​Join us at The Fold in San Francisco for a weekend hackathon building practical solutions across four tracks: DNA Synthesis Screening, Pandemic Early Warning, AI Biosecurity Tools, and Benchtop Synthesizer Security.

​Schedule

​Saturday, April 25: 10:00am - 8:00pm Pacific Time
Sunday, April 26: 10:00am - 8:00pm Pacific Time

​Meals provided: Saturday lunch, Sunday lunch.
