A one-day build day run by OpenAI on Station F's open platform, aimed at the hard part of shipping AI in Europe: doing it without leaking data. You build something real between 9:30 and 20:00 rather than sit through panels, with OpenAI staff on hand. Registration is gated, so apply early. The draw is the room: the Paris builders who actually care about privacy-preserving AI, which in a GDPR-first market is most of the serious ones.
