You have a clear business idea and technology, now it’s time to validate your idea and find your market.

Apply Talk to a startup scout

Whether you are validating a research-driven idea, building toward your first paying customers, or preparing for your first funding round, the YES!Delft Incubator gives you the framework, network, and mentorship to get there.

A 10-week, part-time program for early-stage technology startups working toward problem–solution fit. Teams test assumptions through customer interviews, refine their target market and value proposition, and receive coaching on topics including business models, legal/IP, funding, team development and pitching.

The application process consists of an online submission, review by a startup scout, an intake conversation, a pitch-deck assignment and, for shortlisted teams, a Selection Day jury pitch.
