Software, thought through.
We design and build apps, platforms and AI tools. From Rotterdam.
We are Thinkaholic. A product lab where strategy, design and engineering come together. We keep thinking until we understand, and keep building until it works. For software that lets people live more freely and consciously, that works for everyone and makes the world a little better.
From first conversation to launch day.
Feel
We start with the people who will use it. We talk to them, watch them work and keep asking until we see where it hurts.
Understand
Then we learn your field. Care protocols, tenancy law, GDPR: we read up until we can explain it ourselves.
Think
Only then do we design. Strategy, design and engineering sit at one table, so every choice has a reason.
Do
And then we build it. We launch, watch what happens and keep improving, long after it’s gone live.
A few things we built.

For everyone
If you have poor eyesight, only use a keyboard or own an old phone, you should be able to take part just as easily. We build to WCAG 2.2.
A little better
Lean software on European servers that we run ourselves where we can. Light on energy, and your data stays close to home.
We most enjoy working for those who make life better for people, animals or the planet: in healthcare, education and research, or as a business with a mission.
Thinkaholic is part of MARTEMIAS. When a system serves the public interest, that’s the name we build it under.
What people say
They really think along with every idea that comes up, even the ones that can’t actually work. The sparring and trying things out was refreshing and always fun. Super happy!
Barbara, Client I’d been looking for an app to keep track of what I lend out for ages. Out of frustration I was about to build one myself. Then I found this one. Exactly how I’d have made it!
Sarah, Borrowed · Google Play I was raising money for a school in Uganda and needed a website where people could donate. It was up in no time, clear and beautiful. The donations came pouring in straight away!
Jasmin, Client What a fun and easy-to-use app! All the events and local news in one overview.
jolandaaj, BuurtBabbel · App Store Enthusiastic, skilled and committed. They ask the right questions up front, check along the way that they’re still on track, and make sure we can carry on by ourselves afterwards.
Félicité, Client Unlike many similar apps, this one is actually clear, for things you’ve borrowed and things you’ve lent.
Grotezakpatat, Borrowed · App Store Great! I get good advice and I really feel heard.
Boris, Client Fun outings in the neighbourhood show up that I didn’t know about. Really great, and the app is very clear.
bjorns mazda, BuurtBabbel · App Store Thinkaholic built a beautiful website for our sales and marketing agency. Professional, committed and highly recommended.
Arie, Client Really enjoy it. A nice way to stay in touch with friends, online and in person. Simple and fun to use.

From the founder
We’re never done thinking.
Hence the name.
I started Thinkaholic in Rotterdam in 2016. A lot has changed since, but not the idea: software should genuinely help people.
Even once something is live, we keep thinking. How is it used, what could be better, what else is possible? And you always talk to the people who design and build it.
Martijn van der Laan, Founder
