viadukt competitors and assessment
Company assessmentBroad incumbents
- 1Komma5°: Germany's largest consumer-facing energy transition platform (solar, heat pumps, EV charging, electricity); competes for the same property-owner mindshare in German energy renovation and offers an adjacent software-plus-installation stack that includes marketplace-like trade matching.
- Tibber: European energy retailer and smart-metering platform with software for dynamic tariffs, EV charging, and home energy management; overlaps with viadukt's smart-metering, PV, and EV-charging software positioning from a retail-energy angle.
- Measurabl: Larger, established ESG and utility-data platform for real estate globally; overlaps with viadukt's ESG/PCAF-compliant reporting and portfolio monitoring offering but serves a broader international customer base with a wider product portfolio.
- Enpal: Large German solar/heat-pump/EV provider with proprietary software for customer journey, financing integration, and installer dispatch — comparable to viadukt on the PV/tenant-electricity/economic-simulation dimensions but rooted in physical installation rather than pure software.
Emerging players
- Concular: German PropTech applying circular-economy and material-passport data to building renovation; shares the German building-renovation software target market and overlap with viadukt's sustainability/regulatory reporting narrative.
- Drooms: European virtual data room and document workflow provider for real estate transactions; addresses adjacent enterprise document and data workflows for property transactions — relevant for portfolio managers also using viadukt.
- Viboo: European AI-based HVAC/building-energy optimization startup; addresses similar energy-savings and simulation themes as viadukt's renovation simulator but focused on operational optimization of existing systems rather than renovation planning.
Direct peers
- ecoworks: Berlin-based PropTech focused on serial, industrial renovation of residential buildings in Germany — operating in the same German energy-renovation ecosystem as viadukt and serving overlapping bank, portfolio, and property-owner segments with a digital-first workflow.
- BuildingMinds: European building-performance and ESG data platform for real estate portfolios; comparable to viadukt's portfolio/ESG reporting and building data layer, serving banks, investors, and asset managers with structured building intelligence.
Others
- dena (Deutsche Energie-Agentur): Germany's national energy agency and a viadukt strategic partner; not a direct competitor but the leading ecosystem validator and program operator for energy-efficient renovation, making it the most relevant ecosystem institution adjacent to viadukt's market.
