Hubert + Freihart

What Hubert + Freihart does

Hubert + Freihart is a privately held German engineering and energy systems group headquartered in Eichstätt, Bavaria, founded in January 2015 by Christian Hubert and Michael Freihart. The company specializes in technical building equipment (TGA / Versorgungstechnik) engineering planning across all HOAI service phases (1-9), covering heating, ventilation, sanitation, cooling, electrical, fire protection, and renewable energy systems for public sector clients, municipalities, property developers, and commercial/industrial building operators across southern Bavaria.

The group operates through three legal entities. Hubert + Freihart Ingenieure GmbH delivers BIM-based engineering planning, project management, and feasibility studies using BIM software, EPLAN, AutoCAD, and MH-Software, with deeper specializations in hospital, laboratory, industrial kitchen, laundry, and swimming pool technology. HFG+ Energiesysteme GmbH & Co. KG (founded 2021, rebranded 2024) delivers recurring managed services including MSR-based building automation, energy monitoring via BUS modules, digital twin documentation, and ongoing maintenance. The Hubert + Freihart Gebäudemanagement GmbH & Co. KG provides technical building management. Underlying platforms include MSR (Mess-, Steuer- und Regeltechnik) control systems integrated with technology partners Delta Controls, Loxone, and Robatherm.

The business model blends project-based professional services (HOAI-fee structured engineering contracts) with recurring managed-services revenue from maintenance and energy optimization contracts. Customer acquisition is direct, sales-led, and relationship-driven, with no marketplace or reseller channels. The company serves a mix of public sector (Landkreis Eichstätt, Markt Hohenwart, Gemeinde Großmehring) and commercial clients (Klinik Eichstätt, Sportpark facilities), with three regional offices in Eichstätt (HQ), Ingolstadt, and Nürnberg and a team of 42 employees as of January 2025. Revenue is not publicly disclosed, and the company is founder-owned with no external investors identified.
