Marcin Klimaszewski is the founder of gonogo.design and runs Product Build Day, where product teams and non-coders vibe code their next big thing in a day. His rule: "An idea that cannot survive a day is not worth a quarter." With a background in UX leadership and team building, Marcin has scaled design practices, championed accessibility, and helped organisations turn uncertainty into clear product direction. As a mentor and community builder, he brings a practical, fast-moving approach to product, design, and innovation.

The design process isn't dead, it's compressed," says NNgroup. Everyone can build now, your PM too. AI takes teams from idea to prototype in hours, but speed without discovery still ships the wrong product. Marcin proposes a one-day hackathon for non-code people on product teams, run as rapid discovery: vibe code your bets, get cross-functional teams on the same page, learn before real dev time starts. You'll leave with a structure for running your own, from framing the challenge to turning prototypes into better decisions.
AI is already changing how product teams design, build, test, and make decisions, but what does that actually mean for UX and development day to day? In this panel, Szymon Trzepla, Małgorzata Wyczańska, and Marcin Klimaszewski will explore how AI is reshaping collaboration, accessibility, design quality, delivery speed, and the boundaries between roles. This will be an open discussion, with the audience invited to join the conversation and share how AI is showing up in their own teams.
