Hi, I’m Martijn Reintjes. Dutch entrepreneur, builder and dad of three.

My mission

One day I want to look back and think: we had such a good time together. That’s what drives most of what I do right now.

With Go Super Papa I help busy dads enjoy their family more and feel more confident as a dad. Members get a personal email every morning and an AI chat coach on WhatsApp, both tuned to their family. Small ideas for an ordinary day, a fresh perspective when something is hard, and room to find your own way as a dad. It’s live in the Netherlands, and I’m building the English version.

I think this might be my ikigai: helping dads enjoy their life and family more, helping raise awesome kids, and tinkering with tech and AI to make it all happen.

Psychogoed

Together with my wife I run Psychogoed.nl, an online platform that helps parents raise their children in a positive, solution-focused way. She’s a child psychologist and the knowledge expert; I do business development and the technical side.

When I’m not working

I build things: Lego with the kids, furniture, and our house, which I’m renovating mostly myself. I cook a lot, mostly vegetarian, with the aubergine as my declared favourite vegetable. I love organizing dinners and get-togethers with friends, playing with my kids, and reading (mostly sci-fi, plus business books and biographies). These days you’ll also find me on a trail run or at the bouldering gym.

How I got here

I’ve been starting things for over twenty years:

  • Pepergroen, my game studio, where we built advergames for brands and later iPhone games.
  • FairBodyCare, a fair-trade webshop that turned into an affiliate shop, and then closed.
  • Testing.Agency, a productized service that took the hassle out of A/B testing.
  • Years of working location independent with my wife, from Honduras and Nicaragua to Thailand and the Dominican Republic, always with our home base in the Netherlands.
  • Twenty years in Utrecht, where we gutted and rebuilt a 150-year-old house. Now we live in Nijmegen, in a house I’m renovating again.

My philosophy hasn’t changed much since I started this blog: live a life that generates great stories. The next big one starts in 2027, when we leave for six months of travelling as a family.
