I’m Demmy Onink, a freelance product designer from Amsterdam. I use behavioural science to design products that help people meet their goals and improve their lives. Recently, I’ve helped people choose the right car, make better financial decisions, and properly dispose of their garbage.
Are you looking to align your product with your customers' goals? I would love to help you make it work.

I'm married and a proud dad to three great kids, two of them adults now. I love learning new things, meeting new people, and visiting new places. But what really inspires me is watching my kids grow up, figuring out life and coming up with questions about life that I never think about.
I live and work in the Amsterdam Oud-West. In the same square mile, where I was born and raised. I've seen this area change from an outworn neighbourhood everyone tried to flee, to a popular place everyone wants to live. A place where bearded vegans with yoga mats, replaced the anarchists and small-time crooks. I don't resist it anymore. I wear a flat cap, drink oat milk latte and work in tech. I am an accidental hipster with the appearance of a retired hooligan, much like this neighborhood.
I have worked as a Behaviour Designer, UX designer, UI designer, and Service Designer. Each title expresses a different view on the role of design within the development of a product or service. Today I combine all of these roles to improve products in each stage of development, taking into account both customer's goals and business goals.
What makes us tick?
I think my fascination with behavioural psychology is just me trying to make sense of our sometimes illogical behaviour. We set these great goals for ourselves and then end up doing the exact opposite. It's as if our brains enjoy the irony. Frustrating, yes, but these flaws also make my job endlessly interesting. Regardless of the product, exploring what drives human behaviour never seems to bore.
