Two portfolio companies of the investment platform Realyze Ventures and BitStone Capital have recently been awarded important industry awards: Optiml AG was awarded the immobilienmanager Award 2026 in the category “Digital Solution & Technological Innovation”. aedifion GmbH received the Road to Green Award 2026 in the “Energy” category. Realyze Ventures and BitStone Capital are among the leading European venture capital platforms for the sustainable transformation of the real estate, construction and crafts industries and have been supporting both companies since an early growth phase.
The immobilienmanager Award is one of the established industry prizes of the German real estate industry. In the category “Digital Solution & Technological Innovation”, Optiml was awarded in 2026 for the project “Decarbonization, Capital Efficiency and Performance for a Fund in Europe”. The award was given for the collaboration with Catella Investment Management on the data-driven decarbonisation of a European residential fund with around 40 buildings in eleven countries.
Optiml’s platform uses AI-based optimization models to analyze millions of technical variants, creating a reliable basis for decision-making for restructuring, holding and selling decisions. CO₂ reduction, capital investment, risk and return are systematically comparable. The Realyze Ventures team has been with Optiml since 2024.
aedifion is also an example of this development approach. The Realyze Ventures team has been supporting the Cologne-based company since 2020. With the “aedifion AI Assistant – AI-supported co-pilot for efficient building operation”, the company reached the final round of the immobilienmanager Award 2026 in the category “Digital Solution & Technological Innovation” in addition to the Road to Green award. The solution addresses efficient building operation and demand side management in particular.
With its AI-based cloud platform, aedifion supports owners and operators in significantly reducing energy consumption, CO₂ emissions and operating costs in building operation. At the same time, the current visibility of both companies in relevant industry contexts points to the growing importance of technology-driven solutions for the construction and real estate industry.
“We invest early on in companies that solve key challenges in the construction and real estate industry technologically and accompany them in their access to the market. The fact that two portfolio companies, Optiml and aedifion, are now being recognized in important industry contexts underlines the relevance of this approach,” explains Manfred Heid, Managing Partner at Realyze Ventures.
As a sector specialist, Realyze Ventures invests specifically in technology-driven solutions for decarbonization, digitalization and increased efficiency. The investment platform combines early-stage financing with close access to relevant market players and supports portfolio companies in validating their solutions early, tapping into market use cases and accelerating their growth.
