New Company Bridges the Gap Between Capital and Public Sector Investment Needs

Frankfurt, 10 September 2026 – With the launch of GARBE Infrastructure Invest GmbH, GARBE is establishing an independent investment advisory company within GARBE Infrastructure. The management team comprises Dr. Thomas Kallenbrunnen (CEO), Dr. Tobias Brosze (Chief Technical Officer – CTO) and Nikolaos Thomas (CFO/COO).

The new unit provides investors with access to infrastructure assets with a focus on Germany and supports municipalities, municipal utilities and public partners throughout the entire lifecycle of their projects. In doing so, GARBE draws on six decades of implementation experience and, above all, technical development expertise across projects in all asset classes. Key focus areas include real estate-related infrastructure investments such as schools and public buildings, as well as partnerships with municipal utilities and municipal enterprises in the fields of energy and utilities. Transformation and innovation topics such as battery storage and data centers are also part of the investment approach.

“Institutional capital is ready and available. What is needed, however, are new ways to organize cooperation between the public sector and private-sector expertise – that is exactly what our approach delivers,” says Thomas Kallenbrunnen. “Germany faces enormous challenges in the infrastructure sector. Almost every subsector has a multi-billion-euro investment backlog.”

Tobias Brosze as Bridge-Builder

Tobias Brosze previously served for many years as Chief Technical Officer of Mainzer Stadtwerke AG, where he was responsible, among other things, for investment programs relating to power and water supply as well as for the strategic planning of heat supply in Mainz and the surrounding region. He understands both sides: the expectations and processes a municipal utility or municipality has of a reliable partner, and the requirements investors place on a viable investment. Brosze was already involved as an advisor in setting up the company and is joining the management team upon its founding. He represents the municipal understanding, energy industry expertise, and implementation and operational capability that will define GARBE Infrastructure Invest.

“I know how municipalities and municipal enterprises make decisions, and how to take projects from concept through to implementation,” says Tobias Brosze.
