About OPTIMUSE

OPTIMUSE is a Vienna deep-tech company founded in 2021 by Dominik Pezzei, Fabian Pitscheider and Felix Maximilian Hofer that builds an AI platform for the engineering, renovation and operation of buildings. From existing plans it creates a digital building model, simulates thousands of heating, cooling, ventilation and envelope variants, and recommends the most economical and climate-friendly options for residential, commercial and industrial projects—management cites roughly 70% faster preliminary engineering, about 10% lower construction cost via better system sizing and around 20% additional operational emissions savings. The ~20-person team blends construction, building physics and AI expertise. In October 2025 Optimuse raised a €4 million Seed led by seed + speed Ventures and Blum Ventures, with Matterwave Ventures and aws Gründungsfonds returning, to fund international expansion (Germany, Austria and southern Europe) and scale distribution of the platform for renovation paths such as gas-to-heat-pump conversions and new-build system optimisation.
