Competed to advance wind power

Green electricity is better. For people, animals and the environment. We are convinced of that. And that is why our company is shaped by the certainty that the generation of electricity by wind turbines should not conflict with either species protection or economic viability.

We know a great many of the requirements that wind farm operators, technical managers, authorities and residents place on modern wind energy plants. And it is from this very experience that we draw the experience to offer our customers intelligent solutions. Get to know our young team that is passionate about advancing wind power every day.

Technische Betriebsführung Windkraft

Jochen Rößler | Managing director and founder

Jochen Rößler Fleximaus

“I was born in Schillingsfürst in 1983, completed an apprenticeship as an industrial electronics technician as well as successfully completed my studies as a graduate engineer (FH) in physical electronics. As a technical operations manager for citizen wind farms in Bavaria, I dealt with the issue of bat shutdowns at an early stage.

My personal concern was to provide reliable protection for the local wildlife and at the same time to achieve a significant improvement for both the operators and myself as the manager.

The best solution for me was to engineer our own and flexible system. Our system and my know-how allows us to offer solutions for wind farms with species protection requirements and to significantly increase the performance of wind farms compared to other systems despite compliance with the requirements.”

Christian Freiman | Shareholder

Christian Freiman Fleximaus

“My name is Christian Freiman; I was born in Rothenburg in 1985 and completed my studies as an environmental engineer (FH) from the Weihenstephan-Triesdorf University of Applied Sciences. Since 2013, I have also been working as a technical operations manager for renewable energies.

I came to Fleximaus GmbH through Jochen Rößler – we met years ago at our former employer. When he presented his idea to me in 2014, I was immediately enthusiastic: establishing Fleximaus as our own product on the market together has been a journey with many exciting challenges for me to this day.”

Reinhard Kirchner | Shareholder

“I was born in Bamberg in 1991, have been a farmer practically since birth and have been a technical manager for renewable energies since 2014.

As a farmer, I naturally have a heart for the environment ... especially for my region and the people I live with. For this reason, my father and I have developed a citizen wind farm. We still operate this very successfully with the help of Fleximaus. From there, the step to becoming a shareholder in this innovative company was not far away.”

Markus Nehfischer | Software development

Markus Nehfischer Fleximaus

“In the beginning, there was the unassuming question of whether I could occasionally support Jochen in the software-side development of a new tool called Fleximaus. Over time, the ‘occasionally’ disappeared and many joint ideas and busy years later, the small tool became a comprehensive toolbox, which is useful for renewable energies and nature conservation and for the architecture and development of which I am responsible.

I see nature conservation as a basic prerequisite and renewable energies as an excellent, important way for a future worth living, also for future generations. So my commitment to Fleximaus comes not only from an interest in the professional challenge, but also from conviction.”

Ralf Ehrenschwender | Service and installation

Ralf Ehrenschwender Fleximaus

“I was born in Erlangen in 1997, completed an apprenticeship as a mechatronics engineer and then further training as a state-certified technician specialising in electrical engineering – since then I have been working in the electrical sector and software development.

In 2021, I decided to take the step towards renewable energies and took over the service and installation of our system at Fleximaus GmbH. I have been passionate about electricity from a young age, especially renewable energies, as they are sustainable and therefore essential for the energy transition.”

Alexander Zierbeck | Software development (external)

Alexander Zierbeck Fleximaus

“I am Alex, born in 1987 in the beautiful Allgäu region, and I have a degree in computer science as well as an M.Sc. in artificial intelligence.

Since 2010, I have been successfully pursuing my self-employed activity in the field of hardware and software development.

Since 2018, I have been leading the design and implementation around Fleximaus as an external programmer. My main tasks include integrating the many different interfaces of the wind farms into the Fleximaus system, connecting my own sensors as well as programming various monitoring, evaluation and auxiliary tools. Working together for many years has developed into a close friendship with the team and the subject area, and I am delighted to be a part of it and to be able to bring my expertise to this place with passion.”
