App After Dark: Mobile App Hackathon

AI Builders Club, London AI Hub, and Bilt.me are hosting a mobile apps hackathon! Come with an idea, a problem worth solving, or join a team when you arrive. You’ll have one evening to turn it into something real, using AI to build a mobile app from scratch. You do not need to be a developer. You need a laptop, a willingness to try things quickly, and a tolerance for shipping something a little rough. Build alongside founders, designers, engineers, operators, and people with an idea sitting in their Notes app that has gone ignored for too long. Come solo or with a team. We’ll help match people up. New to vibe coding? ✨ That is completely fine. We’ll share starter challenges, example prompts, and practical guidance to get you moving. The point is not to show up with the perfect idea. The point is to leave with a working first version. Why come? Because talking about an idea is easy. Building the first ugly version is where it gets interesting. The strongest projects will get the chance to demo at the end of the night, with prizes and judging details to be announced. 🍕 Pizza and drinks included. Format Teams of one to three. We’ll kick off with a short intro, share a few optional challenges, then give you the room to build. There will be people around to help if you get stuck, but this is a hackathon, not a lecture. At the end, teams can demo what they made.

Anyone who wants to make something. Vibe coders, aspiring founders, designers, engineers, and complete beginners are all welcome. If you have never written code but have always thought, “someone should build this,” you are probably in the right room.
