(00) Approach

I help teams turn unclear problems into products they can ship.

Most product work starts with competing priorities and incomplete information. I talk to customers, work through the trade-offs with engineering and sales, and turn it into a clear direction the team agrees on.

(03) About

Hi, I'm Josh.

I'm a product owner at Roseman Labs in Utrecht. I studied economics at the University of Amsterdam, then worked in strategy and product design before moving into product ownership.

Outside work I design and build iPhone apps. It gives me a place to take ideas from start to finish and keeps my product and design skills sharp.
