Open House of Energy

What Open House of Energy does

Open House of Energy GmbH (OHOE) is a Munich-based, privately held German energy consulting and software company founded in 2010, serving energy-intensive industrial customers in the DACH region. Its core offering is the Open House Engine, a data-driven platform that combines simulation and feasibility studies to prioritize industrial energy investments on economic grounds, and the Open House Ökosystem, a partner network that delivers implementation, financing, and solution services around the platform's analysis output. Adjacent service lines include Lighting-as-a-Service (Licht-als-Service) for industrial facilities, Abwärmenutzung (waste heat utilization) tied to §17 EnEFG compliance, and an AI-based cost reduction offering (Kostenreduzierung durch KI).

The business model blends recurring software revenue with professional services. OHOE sells Standard and Professional monthly subscriptions to the Open House Engine platform, charges separately for workshops and additional services, and earns managed-service revenue from Lighting-as-a-Service contracts. The company distributes through a direct enterprise field sales motion supported by personal consultation appointments, content marketing (handouts, one-pagers, industry electricity price briefings), LinkedIn presence, and a free test license as a mid-funnel conversion mechanism. Customer segments are enterprise industrial buyers in food processing, paper and tissue, and broader industry and logistics, with stated end-customers described only qualitatively as "multiple renowned companies." OHOE employs 11-50 people, is led by Managing Director Stephan Dorfner, and has not disclosed external funding, M&A activity, or named customer logos in available source material.

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Siemens Smart Infrastructure (Navigator / EnergyIP): Siemens' Smart Infrastructure division sells energy management, sub-metering and building/industrial optimization software plus services. Direct overlap with OHOE's industrial energy analysis and implementation offering, scaled across a global platform.
• Schneider Electric (EcoStruxure Energy Management): Global incumbent offering EcoStruxure energy management software and energy advisory services to industrial and commercial customers. Competes with OHOE for the same industrial energy-management budget, but as part of a much broader portfolio.
• ENGIE Impact (ENGIE Group): ENGIE's advisory and energy services arm delivers industrial energy efficiency, decarbonization, and waste-heat projects to large manufacturers. Overlaps with OHOE on energy consulting and implementation, embedded within a global utility group.
• Bosch Building Technologies / Bosch Energy Solutions: Bosch's energy and building technology businesses sell energy monitoring, building automation, and industrial efficiency solutions. Overlaps with OHOE on industrial energy monitoring and efficiency in DACH, with much greater scale and breadth.
• E.ON Industry Solutions (Industrial Energy Services): E.ON's industrial arm provides energy efficiency consulting, waste-heat recovery, and energy supply solutions to large German manufacturers. Closely comparable on services scope (especially waste-heat and energy cost reduction), and a direct competitor in DACH.
• ABB Ability Energy Manager: ABB's industrial energy management software targets manufacturing and process industries with monitoring, analysis and optimization capabilities. Comparable in industrial customer base and use cases, with significantly broader scope and global scale.

Others

• Carbon Trust: Global climate and energy advisory firm supporting industrial clients on energy efficiency, waste-heat and decarbonization projects. Comparable on advisory and feasibility-study scope, but operates as a pure consultancy without a software platform of OHOE's kind.

Direct peers

• Enel X (formerly EnerNOC): Provider of enterprise energy intelligence software plus demand-side energy services to industrial and commercial customers. Comparable SaaS-plus-services model for energy optimization in industrial settings.
• KISTERS: Aachen-based software vendor specializing in energy data management, energy trading, and environmental IT for utilities and industrial customers. Highly comparable as a German-headquartered vendor selling software plus services for industrial/utility energy optimization.

Regional players

• LichtBlick: Hamburg-based energy company offering distributed energy, demand response, and customer energy services primarily in Germany. Comparable as a German energy services innovator, though more utility/customer-facing than industrial process optimization.
