AI Agents in Fintech - Evening Hackathon
150 developers. One evening. Central London.

🚀 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).
