A sustainable future
At Leukeleu, we believe technology and sustainability should go hand in hand. That’s why we love working with organisations that share this vision. We help companies create solutions that support their core business while also contributing to their sustainable goals — like zero emissions and the UN Sustainable Development Goals — powered by responsible technology.
Our contributions to open source are a strong example. We don’t just build innovative tools — we actively contribute to platforms and technologies that are accessible to everyone.
In an increasingly digital world, the right technical partner makes all the difference. At Leukeleu, we’re committed to being that partner. Together, we develop solutions that support your success and make meaningful impact. That’s how we help build a smarter, more sustainable world.

Core values
Our core values are passion, respect, growth, joy, and collaboration — or as we call it: PROPS (this only works in Dutch, sorry 🙃). These values guide everything we do, shaping how we work and what we build together with our clients.
Passion
We have a deep passion for technology and innovation. Our curiosity drives us to constantly seek smarter, better ways to create digital solutions that make a real difference. We aim to push boundaries and surprise our clients with future-focused results.

Growth
Growth is part of our DNA. Whether it’s about developing innovative products, improving our services, or expanding our own skills and knowledge — we never stop moving forward. That’s how we ensure the best possible outcomes.
Joy
We believe joy in our work is essential. Passion and joy fuel the energy we need to elevate projects to the next level. At Leukeleu, we foster a positive, open work environment that encourages creativity and innovation.
