About

I’m an independent designer & founder of Bureau Hardy Seiler, a design studio focused on brand, digital and editorial experiences. Selected clients include Google, NVIDIA & Science Museum London. My work has been recognized with international awards such as the Red Dot Design Award, iF Design Award, German Design Award & European Design Award. I’m also co-founder & shareholder of Hafven, one of Europe’s largest coworking and makerspace communities. Since day one, Hafven has been a playground for new ways of working, innovating and collaborating. Most recently, I’ve co-founded coapp, a white-label platform that empowers organizations to build and run thriving communities under their own brand – combining messaging, events, memberships, bookings, and payments in a single, seamless solution.
