We are pleased that you are interested in us.

We are also interested in you.

In the work we do, we seek to offer every single customer a solution that is perfect for them – and we’ve been been doing this for 20 years. The will to blaze new trails is in our DNA: we started off as a University of Stuttgart venture that was spun off. To this very day, we continue to work successfully and independently with key players from various market areas as well as with smaller smart pioneers in the industry. Our software is constantly being enhanced and upgraded so that it keeps pace with the fast-changing technology environment and the dynamic energy market. However, our passion remains the same: to find precisely the right solution to meet the needs of every customer – including you, if you would like. It’s a promise!

“The people here are actually doing their jobs far too well.”

(Jan Marco Heinz, Managing Director)

What we have to offer in addition to services.

It is not only our digital solutions that make us unique. There are even more reasons to choose us:

Seven2one icon

We solve your problems.

Seven2one is not a large corporation. We are also not a company that has been spun off from a large corporation. We are an owner-managed company with a team of 45 employees. When you have a contact person at Seven2one, this person is not only a point of contact but also a working partner with decision-making power and expertise who uses their intelligence and listening skills to find out what your goals are and helps you achieve them. They also are passionate about their jobs, because such passion is embedded in our DNA.What we most enjoy about our work is the opportunity to find the solution that best meets your unique requirements.

Application icon

We do this work out of conviction.

As part of a project at the University of Stuttgart, the founders of Seven2one were originally only looking for a modular software solution for the energy market. But it soon became clear how much potential there was in this idea. It’s how the project became a company. And the company has become a full-service provider that today provides you with efficient and tailored software solutions.

Research & development icon

We are people who understand the process.

We are constantly gaining more knowledge because we love our work, and we never gave up on our original goal of conducting great research. This allows you to benefit from our expertise along the entire value chain of the energy industry and includes everything that facilitates the digital transformation of your business.

Team icon

We are one of a kind and have built our business on the unique nature of our team.

Just as we value our clients’ individuality, we also appreciate the variety of personalities in our interdisciplinary team members, who are all pleasant to work with. For us, showing consideration and seeking to help in any way we can are modes of behaviour that are key to our our dealings with you and our work in general. And in our daily experience, they are also a huge factor upon which the success of our company is based.
