WHY WE EXIST
Modern technology valuable for everyone
AI, data and cloud technology shape our new digital reality with many promising opportunities for a better world when used responsibly. For many organizations, however, adopting these modern technologies is still a stretch. It's complex, tech talent is scarce and big investments often end up without meaningful results.
ReturnOnCode exists to overcome this challenge. We enable organizations to extract value from modern technology in a viable way. As a small team with a full range of business & tech capabilities, we can make decisions quickly, operate cost-effectively and navigate between strategy & code instantly. Our approach builds on years of lessons-learned at Dutch tech companies and is best summarized by three characteristics.
Think Big, Start Small
Kickstart brilliant ideas without hassle. No lengthy consultancy or extensive project charters before we make our hands dirty. With short development cycles and experiments we help you to get started in days and stay in control of costs.
People-focused, Tech-driven
Technology is a means to an end. Value depends on whether the technology is adopted by people to improve performance. Instead of making decisions from behind a keyboard, we employ a user-centric approach and relate directly with people who use the technology.
Reliable Code, Special Care
We treat technology as an asset. We invest in a clean, compliant, secure, tested and documented codebase. This way we ensure a solid foundation for continued innovation without impairing technical debt, time-consuming maintenance or hidden costs.
