We believe in a world where waste is prevented, minimizing harm to our planet and people.

Instead of wasting renewable energy, we unlock flexibility to make good use of it.

Instead of increasing loads when dirty fossil fuels are used, Stekker.app postpones loads to moments that are both cleaner and cheaper.

We're hiring!

Meet the team

Erik de Bruijn

Erik de Bruijn

Co-founder and managing director

Driving his electric vehicle since 2013 and harvesting his own solar power since 2015, he wanted to be able to charge at the best times possible. Because there was no application available for this, he developed one himself. Much later, together with Jankees van Woezik, he founded Stekker.app and developed the idea into a service, so anyone can use it. With their company, the primary goal isn’t profits, but to maximize our positive impact. But first we start small and create a great, compelling service that adds value. We want to ensure it’s attractive for anyone to use, not just technology minded people.”

Jankees van Woezik

Co-founder and CTO

I made my first website in 1998 and got into a trajectory to start multiple businesses. Meanwhile I've always freelanced as a full stack developer and after about 10 years of freelancing I ended up at Ultimaker where I met Erik de Bruijn. From the first moment we met we connected on multiple levels which led to us founding Stekker in 2019.

My passion is to work on products and services that are meaningful to people and our society at large. I really enjoy solving such puzzles piece by piece. I want to love what I do and do what I love, work included.

Our mission is really important to me. I'm really grateful that we are able to give people the tools to save emissions and make better use of renewable energy.
