DiLT Analytics raises seven-figure pre-seed to find faults in buildings
What's the deal? DiLT AnalyticsDealroom has a profile for this one. Try Dealroom →, a TU Graz spin-off, has closed a seven-figure pre-seed round to scale FaciliMind, its software for detecting and diagnosing faults in building systems. Vienna deep-tech fund Noctua Science VenturesDealroom has a profile for this one. Try Dealroom → led the round, with support from Austria Wirtschaftsservice (aws)Dealroom has a profile for this one. Try Dealroom → through its Seedfinancing Deep Tech program.
What does it do? Large buildings generate thousands of data points from heating, ventilation, and air conditioning systems, yet many faults — leaking valves, ventilation running needlessly at night — go unnoticed and quietly inflate energy bills. FaciliMind connects a single device to a building's existing control system, builds a digital model within days using a knowledge graph, then flags faults ranked by severity.
The software surfaces energy savings of between 5% and 30%, depending on the building. Customers include TU Graz, TU Wien, the Bundesimmobiliengesellschaft (BIG), IG Immobilien, and several industrial firms.
Who's backing it? Noctua Science Ventures is a joint venture of Speedinvest and Austria's technical universities, focused on pre-seed bets on research-based spin-offs. "With Noctua Science Ventures we have found a partner who knows both: the technical challenges of a deep-tech product and the path to commercialisation," said chief executive officer Theresa Kohl (translated from German).
Philipp Stangl, managing director of Noctua, praised a "credible, technically differentiated approach" (translated from German). The aws grant requires a clear technological leap over existing solutions.
The backstory: DiLT Analytics was founded in late 2021 by professors Franz Wotawa and Gerald Schweiger as a spin-off of TU Graz's Institute of Software Technology. The startup, which employs 11 to 20 people, is involved in more than 20 research projects via its DiLT Research arm. It won the Energy & Climate Protection city pitch at the 2025 #glaubandich Challenge and picked up the ÖGUT environmental prize the same year.
What could go wrong? DiLT is not alone. Cologne's aedifion offers a rival building-technology platform, and Canada's BrainBox AI, which uses AI to control heating and cooling, was acquired by US climate firm Trane TechnologiesDealroom has a profile for this one. Try Dealroom →. DiLT differentiates on automated root-cause diagnosis.
The signal: With buildings generating most of their emissions during operation, software that cuts energy use without new sensors fits a growing push to run existing stock more efficiently. Early institutional customers and a deep-tech fund suggest the operational-efficiency angle is finding buyers.
