The Engine Room Where ideas take shape and momentum begins.

You might be a computer science major. A PhD. A researcher. A recent grad. Someone at DeepMind or Google. Or just a person who loves making things.

We built The Engine Room for you.

Accelerators take too long. Hackathons end too fast. We wanted something in between — a week that's long enough to build something real, but short enough to fit into your life.

You get capital, mentorship, and a community of people who care about the same things you do.

No long application process. We take no equity. No pressure to pitch something polished. Just one week to build. To learn. To get unstuck.

Chapter One and AI Engine are launching this program in partnership with ElevenLabs, AWS, and others.

Why? Because we've built products used by hundreds of millions of people. We've backed founders who've gone from zero to unicorn. And now, we're looking to support the next wave of technical founders in Europe — and help them get started.

London is full of talent, energy, and ambition. We think the next legendary companies will start right here — in a room of eight teams, some laptops, and a lot of momentum.

That's what The Engine Room is about: a place to start, surrounded by people who believe in building. That's all that matters.
