Twenty-five portfolio
companies. One room.
Twenty-four hours.

A cross-portfolio AI hackathon at Google Bastille, Paris, built so every team leaves with a working prototype, a credible path to production, and a peer network they will actually use.

The Venue

Bastille Auditorium. Google’s Paris office.

A purpose-built event space inside Google Paris. Full production rig, livestream-capable, walking distance from Gare Saint-Lazare. The room teams will actually build in, not the room they see in a photo.

Six Reasons This Matters

Send four to six people.
Bring home a prototype, a peer network, and a path to production.

Prototype
A working AI prototype in 24 hours.
Your team picks a real pain point. They leave with a prototype ready to pilot within weeks, not a slide deck about an intention.
Outcome
Working build, demoable on day one.
Support
Engineers in the room, not links in an inbox.
On-site Google Cloud engineers and AI mentors. Architecture review, code guidance, and real-time unblocking from practitioners who ship this stack.
Outcome
Questions get answered in minutes.
Credits
Free GCP and Gemini credits.
Experiment freely without worrying about cloud bills or license constraints. Credits cover the prototype window and spill into early pilot work.
Outcome
Remove the procurement friction.
Network
Twenty-five peer companies in one room.
Meet your counterparts across the Eurazeo portfolio. Build relationships that extend beyond the hackathon -- shared learnings, hiring referrals, joint experiments.
Outcome
A network you will use next quarter.
Proof Point
A concrete AI case you can take to the board.
Return to leadership with a validated use case, a feasibility read, and a credible path to production. Replace abstract AI strategy with a line item.
Outcome
Board-ready artifact, not a slogan.
Accountability
30 and 90-day follow-through.
Every portco gets a structured 30-day readout. Premium tier adds 60 and 90-day milestone reviews, tracking the path from prototype to revenue or efficiency impact.
Outcome
Momentum, not a one-off.

The Arc -- Prepare, Build, Sustain

Hackathons fade. This one has a runway and a tail.

A runway before so teams arrive with scoped problems, and an accountable tail after so prototypes make it to production -- the move that closes the loop on Antonin's fear of a day that ends with applause and nothing else.
