Product Build Day Pro

A one-day, hands-on product workshop in Berlin run by Marcin Klimaszewski, who led a 35-person UX team across five countries at Sanoma Learning before going solo and now runs product discovery workshops across Europe. The format is build, test, decide in a single day. You get a brief and set the metric that would kill the idea, spend about two hours building a working prototype with AI (no coding needed), then test it the same day with AI testers and the other people at your table. It closes with three-minute pitches and selected demos for the room. You leave with a working prototype, usability findings, a first customer-test plan and a certificate. A curated group of 12, in English, in person at Circuit Berlin. Lunch, tools, a prep call and a 45-minute follow-up with the trainer are included. Paid: 790 EUR per seat, or 690 EUR if you book by 31 October. Invoiced to your company, no VAT. Every third seat is free. Seats transfer to a colleague until 24 November but are non-refundable.
