What MOMENI Ventures does

MOMENI Ventures is the venture capital and innovation arm of MOMENI Group, a privately held, founder-owned Hamburg-based real estate investment and development firm founded by Ali-Reza Momeni in 2004. The Group manages more than €8.5 billion in assets under management and has realized development projects exceeding €6.5 billion in value across prime German and selected European city locations, operating through four integrated divisions: Investment Management, Development, Real Estate Management, and Ventures.

MOMENI Ventures invests in early-stage technology companies along the real estate and construction value chain, with a stated mission to accelerate decarbonization of the real estate sector. Its core product is the Realyze Ventures investment platform, co-initiated in 2023 with Bitstone Capital (a ZECH Group partner company), which targets startups advancing sustainable development through digitalization, automation, new material technologies, and innovative energy concepts in the built environment. Disclosed portfolio investments include alcemy (CO2-reduced cement), aedifion (building AI and energy optimization), limehome (digital hospitality), WiredScore (digital connectivity certification), Wirelane (EV charging infrastructure), and Equiem (tenant experience software).

The business model combines balance-sheet corporate venture activity with the externally-scaled Realyze Ventures fund structure, generating returns through capital appreciation and potential carried interest while leveraging the parent group's operating platform as a distribution channel and pilot deployment environment for portfolio companies. The unit is led day-to-day by Director David Nadge under the executive oversight of Managing Director Tim Fischer, with a headcount of 1-10 employees and no separately disclosed revenue.
