Clas Gunneberg has stabilized Polarium, strengthening its financial standing, securing additional investments, and refining its operating model. These efforts have laid a solid foundation for future growth across Polarium’s three business areas — Telecom, Commercial & Industrial (C&I), and Residential.

As the company moves into its next phase, leadership has transitioned from Clas Gunneberg to Leif Ottosson.

“I am excited to lead Polarium as we continue delivering robust energy storage solutions, supporting grid stability, and driving the integration of renewable energy. With a strong technology foundation, we are well positioned in a rapidly growing market,” says Leif Ottosson, CEO of Polarium.

Over the past four months, Leif has worked closely with Polarium’s leadership team, focusing on the company’s supply chain and manufacturing operations. Now stepping into the CEO role, he brings a clear vision for driving growth and continued innovation.

Leif Ottosson has extensive leadership experience in the power management, industrial, and technology sectors. He previously served as CEO of Cobham Satcom and Navico Group. He holds an MBA from Harvard Business School and a BSc in Finance and Mathematics from Northern Arizona University.

“Polarium is better positioned than ever to serve our customers. We extend our gratitude to Clas Gunneberg for his contributions and welcome Leif Ottosson as CEO to lead the company into its next chapter,” says Harald Mix, Chairman of Polarium.
