Austrian Deep Tech Startup Optimuse Raises €4 Million In Seed Funding

Optimuse’s AI platform helps builders, developers, and planners identify the most cost-effective and low-emission solutions for heating, cooling, ventilation, and building envelopes in both new construction and renovation projects.

By analyzing existing plans and documents, it creates realistic digital building models, compares thousands of design options, and delivers actionable recommendations. This ensures early design decisions optimize both costs and emissions for decades to come.

Optimuse transforms building plans into actionable insights. The platform quickly creates a realistic, simulation-based digital model from existing documents and evaluates modernization options such as heating upgrades, conversions, or switching from gas to heat pumps quantifying impacts on CAPEX, OPEX, CO₂ emissions, and comfort.

The outcome is reliable cost-benefit analyses, with transparent assumptions, sensitivity checks, and prioritized action plans that focus investments, reduce implementation risks and accelerate CO₂ savings. By analyzing early designs, Optimuse identifies energy-efficient variants and calculates optimal sizing for building systems, ensuring lower investment and operating costs while achieving efficiency and comfort targets effectively.

According to Dominik Pezzei, Managing Director and co-founder of Optimuse, buildings are becoming increasingly complex, both technically and in terms of regulations.

“Our AI solution provides clarity: it compares variants in a very short time and recommends the most sustainable and economical solution. This enables our customers to plan, transform, and operate buildings in a future-proof and cost-efficient manner."

The funding round was backed by Seed+Speed Ventures and Blum Ventures, alongside existing investors Matterwave Ventures and Gründungsfonds.

Alexander Kölpin, Managing Director at seed + speed Ventures, shared: "What convinces me about Optimuse is the combination of sound technology and practical application: using digital simulations, the team shows early on in the engineering phase which renovation measures are technically feasible and also economically viable.

In a market with enormous renovation needs and strict efficiency requirements, this is a real game changer."

According to André Hammerer, Managing Director at Blum Ventures: "Optimuse addresses one of the biggest issues of our time: the sustainable transformation of the building stock. With its combination of AI, building physics, and practical simulation, the team creates real added value for builders, planners, and operators."

With the new funding, Optimuse is fast-tracking the global expansion and adoption of its AI solutions for building engineering, renovation, and operations.
