02upcoming & running validation labs per focus area

Once a brilliant idea is discovered and shaped, there comes the role of a Validation Lab to help bringing this idea to the market. Because each industry has their own challenges, own culture and own opportunities we create validation labs specifically tailered to focus areas such as medtech, blockchain, cleantech, edtech, aviation, and more.

A Validation Lab acts as a 3 months pressure cooker, when in one day per week, early stage startups are brought together to validate their business idea and find their product and market fit.

Goal: Find your market/product fit. We use our in house developed methods based on our 12 years of experience and using some of Steve Blank’s Lean Launchpad and Alexander Osterwalder’s Value Proposition Design, Talking With Humans by Giff Constable, . You will talk to as many potential customers as possible to test your assumptions and validate your idea. Validation Lab is the way to prepare for our acceleration program.

What: 3 months of validation with weekly peer-to-peer sessions and workshops. Receive input and feedback from fellow participants, experienced trainers and personal mentors. Your goal is to find out your market/product fit, a validated customer segment and a value proposition design that responds to the actual needs of your customer.

Meet the Startups: Validation Lab alumni participate in Meet the Startups: a day dedicated to showcasing, networking, and matchmaking. The event is focused on facilitating effective connections between companies, potential clients and/or potential investors.

Selection criteria: innovative technology, motivation, availability, coachability & team of 2 or more cofounders.

Program fee of €1250,- (exc. VAT) per team of 2 founders and €500 (exc. VAT) for every next founder participating in the program. The fee covers program costs, working space, workshops, lunch & drinks, access to YES!Delft network, coaching and workshop materials incl. books, brainstorm canvasses.


YES!Delft’s tech incubator is located right in the midst of The Netherlands’ technological innovation, the campus of TU Delft.

The main hall is designed to inspire and stimulate connections to accelerate innovation.
