Entrepreneurship Festival Hackathon (ESCP Blue Factory)

A one-day build sprint run by ESCP Blue Factory, the business school's incubator, as part of its Entrepreneurship Festival. Founders bring real problems from their own ventures, and twelve teams each pick one and build a working prototype by the evening.

The day runs 09:00 to 20:00 at The Delta: kick-off and team formation, a vibe-coding crash course at 09:30, case presentations at 10:00, then building until user tests at 17:00 and demos in front of a jury at 18:00, with the best three solutions recognised. Mentors support every team and Lovable is giving the teams free credits. Hosts are Charlotte Neuville, Andreas and Paolo Trecate.

Free, approval required. Join as a hacker, as a mentor, or bring a case from your own startup.

Why go: a founder with a stuck problem gets twelve teams' worth of attention on it in a single day. Good for builders and students who'd rather ship something real than sit through talks.
