about this event
AI Agents in Fintech - Evening Hackathon. 150 developers. One evening. Central London. Build autonomous AI agents that handle real financial operations - agents that don't just analyse money, but move it. Ship a working prototype in three hours and demo it live to judges from Stripe, Meta, and the 10 Downing Street AI Team.
Schedule: 5:15 PM - Doors open & registration; 5:45 PM - Opening: mission briefing, tracks and scoring explained; 6:00 PM - Hacking begins. Go solo or team up (max 4 per team); 7:30 PM - Pizza - keep building; 9:00 PM - Code freeze. Submit via the event page; 9:05 PM - Judging & finalist selection; 9:30 PM - Finalist demos; 9:50 PM - Awards; 10:00 PM - Close.
Why Join? Ship something real - walk out with a working fintech AI agent you built in one evening. Win £2,000 - cash prize for the overall winner. Stripe credits - £5k, £3k, and £1k in credits for track winners. Side quests - bonus prizes for creative builds beyond the main tracks. Meet your next co-founder - 150 of London's sharpest AI and fintech builders in one room.
Tracks: Two tracks, revealed at the opening briefing. One hint: your agent will be handling real money movement - think autonomy, policy, and auditability. Plus bonus side quests for builds that go off-script.
Who Should Come? Developers, ML engineers, and technical founders who want to build with AI agents in fintech. Come with a team of up to 4, or join solo and pair up on the night. Bring: your laptop, a charger, and an idea (optional - tracks will spark plenty).
Judges: Jan Stehlik - Briefcase; Fionn O Colmain - Stripe; David Gelberg - 10 Downing Street AI Team; Dominic Hudson - AI at Meta; Akash Bajwa - Earlybird.
Hosted By Briefcase × Stripe. Organisers: Jan Stehlik (Briefcase) & Fionn O Colmain (Stripe).
