Z-Group Passes the Torch to the Fourth Generation

Zeintra has announced that after over four decades in company management, owner Max Zeintl is handing over operational responsibility of the company to the fourth generation. Starting in 2025, Salome Zeintl and Simon Zeintl, the fourth generation of Max Zeintl’s family, have taken over leadership. Salome Zeintl will head the group and focus on technical brushes at zeintra AG and filaments at smartfilaments AG.

“It is a great pleasure to continue our family’s legacy – with a focus on continuity, quality, and future viability,” she says.

Her brother, Simon Zeintl, is concentrating on dry ice solutions with polarjet AG and cleaning technologies with electroclean AG, aiming to further expand this business area.

The roots of the Z-Group go back to the founding of zeintra AG – the oldest company in the current group with a history of 112 years. For decades, zeintra AG has been a reliable partner in Wil for high-quality technical brush solutions. From zeintra, the current Z-Group gradually emerged through continuous innovation, entrepreneurial spirit, and visionary leadership. The establishment of additional companies like smartfilaments, electroclean and polarjet AG expanded the range of services and continuously strengthened the group’s market position.

“I look back proudly on what we’ve achieved and am pleased to see the next generation taking the lead,” Max Zeintl says. Together with his wife Mirjam Zeintl, he developed zeintra AG and founded and built up the sister companies. Alongside Jürg Solenthaler, the technical director, they continue to shape the companies to this day.

Max Zeintl will remain closely connected to the business as Chairman of the Board of Directors.

“We are writing the next chapter – together with our team, our customers, and our partners,” says Simon Zeintl.

The Z-Group has always emphasized long-term relationships, quality, and innovation. The Wil location has played – and continues to play – a central role in this. The companies are not only economically anchored here but are also socially engaged. Strong ties to the region, the trust of employees, and the collaborative exchange with customers form the foundation for sustainable success.

Z-Group Companies include:

• zeintra AG

• smartfilaments AG

• electroclean AG

• polarjet AG

With this generational change, a new chapter begins in the long and rich history of a company deeply rooted in Wil. “I look back proudly on what we’ve achieved and am pleased to see the next generation taking the lead,” says Max Zeintl.
