meteoviva appoints Achim Berg as Chairman

Date: 25 Jun 2026
Category: Portfolio news

Technology veteran joins to support its expansion following Bregal Milestone's majority growth investment

meteoviva GmbH (“meteoviva”), a pioneer in AI-powered predictive building energy management, today announced the appointment of Achim Berg as Chairman of the Board. The appointment follows Bregal Milestone’s majority growth investment announced in May 2026. meteoviva’s intelligent solutions combine a proprietary physics-based thermodynamic model with AI to deliver energy cost reductions of up to 45 percent across large-scale commercial real estate portfolios, without structural retrofits.

Achim brings more than three decades of leadership experience across technology, software and digital businesses. He served as President of Bitkom, Germany's digital industry association, from 2017 to 2023, and spent nearly a decade as an Operating Partner at General Atlantic. Before that, he was Chief Executive of arvato AG, Bertelsmann's largest division with more than 70,000 employees, and a member of the Bertelsmann executive board. He has also held senior roles at Microsoft, including General Manager of Microsoft Germany and Corporate Vice President of its Windows Phone division, as well as earlier positions at Deutsche Telekom, Fujitsu Siemens Computers and Dell.

As Chairman, Achim will work with meteoviva's management team and Bregal Milestone to accelerate the company's growth in new European markets, advance its AI and autonomous-control roadmap, and broaden its solution suite.

"meteoviva is positioned at the intersection of two major shifts: the regulatory push to decarbonise buildings and the adoption of AI in how they are managed. Its proven technology platform and clear customer proposition give meteoviva a strong foundation to extend its leadership across Europe. I look forward to working with the meteoviva team and Bregal Milestone to bring meteoviva's platform to more customers and support the company's next chapter."

Achim Berg

Chairman - meteoviva

"We are delighted to welcome Achim to meteoviva. His experience will be highly valuable as we continue to strengthen the capabilities required for our next phase of growth. We look forward to working closely with him."
