The town of Pfullingen lies at the foot of the Swabian Alb. A success story "Made in Germany" began in 1953 in Bollstraße there. In the 70 years since then, the group of companies has hardly stood still—there has always been something to do: new products, new cooperations, new companies. For us, the future needs origin, which is why we never forget our Swabian virtues.

PRETTL Ventures is home to exciting and sustainable companies. From solar energy to software development, the portfolio of our companies is sustainably strong. Together, we strive to achieve a major goal with our values and economic aspirations: a completely sustainable group of companies.

What Are We looking for?

We are looking for visionaries. Big words, big responsibility. And this responsibility must be shouldered. Ecopreneurs have proven that their ideas generate sustainable added value. Coupled with our ambitious goal of sustainable production from 2025, we pave the way for ecopreneurs to realize their innovative ideas. Together with us as an experienced, strong partner, ecopreneurs can take the next step with their companies—towards growth, towards success.

Our Innovation-Hubs

What distinguishes an investment with PRETTL Ventures?

For us, the principle of best ownership applies. We decide in close consultation to what extent we want to invest in a company. Whether it is a complete takeover, a partial participation, or other options—it has to be the right fit for both sides. This is the only way we can be successful together! We want to be THE safe home for European start-ups!

For a true eco-preneur, the environment always comes first. After all, every economic decision making has an impact on the environment. The PRETTL Group made a commitment in 2020—not just a simple "yes" to sustainable production but a clear commitment to promoting sustainable products. A clear "yes" to a sustainable group of companies. This promise to current and future generations is our driving force.

Our strong team introduces itself

The management of PRETTL Ventures combines comprehensive industry knowledge, strategic thinking, and years of experience. With a clear focus on innovation and sustainability, our management leads each company in the group towards targeted and successful growth. Thanks to their expertise in technology, production, and international business, they serve as competent contacts for our partners and customers. Together, they drive growth, efficiency, and sustainable solutions for a strong future.

 

Willi Prettl

In a family business that is already in its third generation, no one from the founding family should be missing. Willi Prettl serves as a sparring partner and source of ideas for the management. He manages the business of the PRETTL Group together with his cousin Johannes Prettl. "Within the ventures, we rely on committed ecopreneurs who develop their companies independently, sustainably, and with a long-term focus on the market. They enjoy a high degree of freedom in their actions," says Willi Prettl. He countinues:

"In order to realize our visions, we as shareholders rely on the BEST OWNERSHIP principle. In concrete terms, this means that we select the best ownership relationship or partnership for each company."

Gerhard Heilemann

Gerhard Heilemann heads the management team. The 61-year-old brings extensive and valuable experience to the company, particularly in the areas of marketing and sales. This aligns with PRETTL Ventures' ambitious goal of building strong and sustainable brands. Before joining PRETTL, the electrical engineering graduate and holder of an Executive MBA had already worked for other large and well-known companies in Baden-Württemberg. In between, he also ventured into self-employment as a management consultant in the field of digitalization. His enthusiasm for green energy and sustainable products, combined with his experience, makes him a reliable partner for any company within PRETTL Ventures.

Alexander Wirth

Alexander Wirth's experience and knowledge in the field of sustainable energy are inextricably linked to the name REFUsol. Under his leadership as CFO, REFU Elektronik reached its full potential, developing a sustainable label "Made in Germany" that was continuously expanded. As a long-standing Managing Director at PRETTL, he knows all the companies within the ventures and has contributed his expertise and ideas to many of them. He has created structures, pursued ideas, and even rejected some—always with a focus on leaving a sustainable core in a company. His prudence and analytical skills characterize his leadership style.

Klaus Nagel

For Klaus Nagel, PRETTL is both a natural fit and a personal passion. In the 1990s, the 61-year-old COO of PRETTL Ventures helped establish and develop the PRETTL Group's site in Greenville, SC, North America. After his time in America, Klaus Nagel gained valuable experience in the renewable energy sector, holding responsible positions such as Senior Vice President of Operations and General Manager of Europe Battery Systems before assuming his role as COO of Ventures in September 2022. Klaus Nagel is looking forward to his tasks within PRETTL Ventures with great confidence, as the brand, company portfolio, and product offerings present enormous potential and great opportunities for our company.
