About us
Renuo is a software engineering company. We have been developing digital solutions for 15 years and often support companies over many years. This requires technical expertise, curiosity and people who enjoy working together to tackle challenging problems. We have plenty of them at Renuo.
How it all began
Renuo has been in existence since 2011. The story of how our current managing director, Samuel Steiner, joined the company actually says a lot about how we operate: he was originally a customer. It was only later that he switched sides. We spent our early days as a group of four in the ETH canteen. Today, there are 23 of us in Wallisellen.

I was Renuo's first customer. I was so impressed with the company, I just had to switch sides.

Why we exist
We’d rather not do something at all than do it half-heartedly. This attention to detail is what drives us. Software needs this more than most, because it’s never really finished – it has to evolve over the years. That only works if the same people stay on board long enough to understand why the code looks the way it does.
That’s why we build long-term relationships, both with our clients and within our own team.
What we do
How we do this
In practical terms, this means that whenever we receive a request, we first ask what the underlying problem is before we get started. And we do not automate any process without first questioning it. The same applies internally. Employees have been able to get involved with Renuo for some time now. It took a few attempts before we arrived at this model. Seven colleagues have now joined as partners.
What we believe in
We are guided by five values. For us, this means: we’d rather deliver a little later, but reliably. We make decisions as a team, not on our own. We stick to our own Code Style Guides, even when it’s a bit of a slog. We’re constantly learning, because a large part of our tech stack will probably look very different in five years time. And we show our clients how their software works, rather than keeping them dependent on us.
We foster and value high-quality work while keeping the goals in sight. We are competent.
We actively engage in seeking new solutions. We believe in continuous learning.
We provide freedom and hand over responsibility. We have as few rules as necessary.
We stand by our convictions, and our actions are predictable. We keep our word.
We value close collaboration. We shape our company collaboratively. We are sparring partners: for our customers, for each other, and for the open-source community.
What we give back
We want committed people. And lead by example. Thus, our story starts with a simple belief: success demands responsibility. Since day one, we have been uncompromisingly committed to open source. We don't just use free software; we take ownership of its security and future. With many of our projects built on Ruby, we actively support Ruby Central and proudly stand as the first Swiss company to join the Rails Foundation. We also spearhead the development of the cancancan library, which has been downloaded over 52 million times globally. Explore all our open-source contributions here.
Commitment
But a company's impact must go beyond code. That's why we give 10 % of our annual profits back to society and the environment. Because true participation matters to us, our employees choose exactly who they want to support. In 2026, our donations went to the Swiss Guide and Scout Movement, Ocean Care and the Wikimedia Foundation. Because one of our most important core values is: We create together.
