As a kid, I built Lego cities just to see how creatively I could destroy them - power outages, disasters, alien invasions. That mix of building and breaking stuck with me and led me to business schools in Estonia and Spain, and product development roles in international startups. Creating products, you can’t control everything, you have to design for uncertainty and failure. Cities.. these are the biggest, messiest products we’ve ever made. My interest here never really faded, so I got into urban innovation, things like circular construction, adaptive reuse, city-as-a-service ideas. The role of service design here? It’s how you work with silos, scarcity, and cycles instead of fighting them. If these are inevitable, we’d better learn to use them.
