The Flywheel
The European Onchain Catalyst
Where European builders go from momentum to escape velocity.
The Problem
There's a dead zone between hackathon demos and Tier-1 accelerators.
Hundreds of European teams build promising prototypes every year. Then they stall. No structured path from prototype to investable company. No mentorship that understands onchain. No ecosystem pulling them forward.
Founders burn months without direction. The best talent either gives up or leaves Europe. The ecosystem loses momentum.
The gap isn't talent. It's infrastructure.
The Program
Three stages. One flywheel.
Sustained effort creates compounding energy. Each stage builds on the last until you reach escape velocity.
Momentum
Continuous cohort. Always open, always selective.
The entry point. Teams join a rolling cohort with structured weekly check-ins, build-in-public accountability, and peer feedback loops. You prove you can ship consistently before anything else.
- ◦Weekly builder syncs and async updates
- ◦Build-in-public framework and accountability
- ◦Peer review with other cohort teams
- ◦Access to the urbe.eth builder network
Acceleration
Intensive sprints. Personalized mentorship.
Selected teams from the momentum cohort enter focused 8-week sprints. One-on-one mentorship from experienced founders and operators. Modular curriculum tailored to each team's stage.
- ◦1:1 mentorship with domain experts
- ◦Product-market fit workshops
- ◦Tokenomics and onchain strategy sessions
- ◦Fundraising preparation and pitch refinement
Escape Velocity
Final push. Demo day. Ready to fly solo.
The final intensive. In-person sprint in a major European city, culminating in a demo day in front of investors, ecosystem partners, and the broader community. You leave with everything you need.
- ◦In-person co-working sprint
- ◦Investor introductions and warm leads
- ◦Demo day at a major ecosystem event
- ◦Ongoing alumni network access

Founding Sponsor
Backed by
Base is the founding sponsor of The Flywheel. This means builders in the program get direct access to the Base ecosystem — from technical resources to visibility at major events.
Projects are evaluated against the Base Standard: onchain traction on Base, user stickiness, and builder consistency. If you're building where users are, you're building on Base.
What this means for builders
Base-native focus
Build where users and liquidity already live.
Ecosystem access
Introductions to the Base team, grants, and partners.
Event visibility
Demo days at ETHGlobal and major ecosystem events.
The Team
Built by builders.
The Flywheel is organized by urbe.eth, the leading onchain builder community in Europe.
