What Open Energy does
open energy AG (operating as Open Energy) is a Vienna-based, private Austrian integrated energy services company founded in 2014 by founders with up to 25 years of energy and IT industry experience. The company plans, finances, builds, operates and services decentralized energy infrastructure — heat pumps, district heating stations, gas condensing systems, solar thermal, and photovoltaic installations — for multi-unit residential complexes (≥20 apartments) and commercial properties (≥20,000 m²), primarily in the Vienna and Tirol regions of Austria. Energy delivery is billed to end users under the Austrian HeizKG framework, providing a regulated recurring revenue layer.
Underpinning the physical infrastructure is a proprietary IoT-based energy monitoring and software stack. Each managed facility is equipped with the company's own Störmeldesystem MALIS fault-reporting unit and an on-site weather station; data from electricity, heat, cooling, water, natural gas and bus-compatible meters is aggregated into the Energie-Monitoring SaaS platform with dashboards, trend analysis, intelligent correction values and export to SAP R/3 IS-U billing systems. Adjacent SaaS products include Index-Cloud for automated price-index management, Digital Signage for in-building display, and the Open Solar community-PV billing module operating under ELWOG §16a. A separately licensed water tightness testing (WDP) service — using a proprietary night-camera high-frequency measurement system — has established the firm as the stated market leader in Vienna for this regulated quarterly compliance service.
The business model combines multi-year recurring contracts (energy delivery, technical services and SaaS subscriptions) with project-based professional services (WDP, Anlagen Quickcheck, contract analysis, energy audits). Go-to-market is sales-led and enterprise field-sales oriented: property owners and housing associations engage via a structured website inquiry form, with regional offices in Vienna (East) and Innsbruck (Tirol, West) supported by dedicated 24/7 emergency hotlines. Ownership is founder/management-led with no disclosed external investors; governance follows the Austrian AG two-tier structure with a Managing Board (Sales/Marketing/Finance; Technology & Operations) and a Supervisory Board chaired by Mag. Maximilian Unterrainer.

Open Energy competitors and assessment
Company assessmentEmerging players
- Tibber: European digital energy retailer combining dynamic electricity tariffs with smart-home and energy-management software for residential customers. Adjacent competitor for the energy-management SaaS and customer-facing dashboard layers of Open Energy's stack.
- Smappee: Provider of smart energy monitoring, EV charging, and solar management solutions for residential and commercial buildings in Europe. Overlaps with Open Energy on IoT-based energy monitoring for multi-unit residential and small commercial sites.
Direct peers
- Kiwigrid: European SaaS provider of energy management and IoT platforms for utilities and ESCOs, aggregating data from heat, electricity, PV, and other assets. Closest direct competitor to Open Energy's Energie-Monitoring SaaS platform from a product-technology standpoint.
- DEXMA: Cloud-based energy management SaaS platform enabling multi-site energy monitoring, analytics, and benchmarking for buildings and portfolios. Directly comparable to Open Energy's Energie-Monitoring product in functionality and customer base.
- Sonnen GmbH: German provider of residential solar and battery storage systems with virtual power plant aggregation, comparable to Open Energy's PV and energy-as-service model for residential multi-unit buildings, though battery-storage-centric rather than heat-pump-centric.
- Wien Energie: Austrian municipal utility serving Vienna with decentralized heat, district heating, PV, and energy services for residential and commercial properties. Direct competitor for Open Energy's core Vienna territory on heating supply and renewable energy services.
Broad incumbents
- E.ON Energie Deutschland: One of Europe's largest integrated energy services companies offering electricity, gas, heat, PV, EV charging, and energy management for residential and commercial customers. Represents the scaled incumbent direction Open Energy's ESCO-plus-SaaS model could emulate if it grew.
- EVN AG: Large Austrian integrated energy and environmental services utility with heating, electricity, gas, and energy services across multiple federal states. Overlaps with Open Energy in heating supply, energy efficiency, and decentralized generation, but operates at much larger scale and broader scope.
Regional players
- KELAG: Carinthian integrated energy utility providing electricity, heat, gas, and energy services to residential and commercial customers in southern Austria. Comparable regional energy-services model with similar mix of heating supply and renewable generation offerings.
- Energie Steiermark: Regional utility for Styria offering district heating, gas, electricity, and energy services to residential and commercial customers. Comparable integrated energy-services model in a different Austrian region, illustrating how Open Energy's offering could be replicated by regional utilities.
