What Cosimo GmbH does

Cosimo Investment Group GmbH is a privately-held German real estate investment and development company headquartered in Duisburg, North Rhine-Westphalia, founded in 1994. The company operates through three wholly-owned subsidiaries — Cosimo Engineering (project planning and architectural optimization), Cosimo Construction (turnkey building delivery with 28 years of construction experience), and Cosimo Asset Management (property administration, tenant structure optimization, and revenue maximization) — that together cover the full real estate lifecycle from initial planning through construction and ongoing property management.

The company generates revenue through project-based real estate development, construction contracting, and managed services. Its core revenue streams include turnkey construction project delivery (one-time project revenue), professional project planning services (fee-based), and ongoing asset management (managed services). The go-to-market motion is direct enterprise sales targeting institutional investors, social housing companies, municipal developers, and commercial/hospitality operators, with projects executed across the entire German Bundesgebiet. Named institutional clients include PATRIZIA (€500M Berlin JV), WBM (441 apartments in Alt-Hohenschönhausen), Berlinovo (941 apartments in Berlin-Mitte), and Premier Inn (two Berlin-region hotels).

Financially, Cosimo reports €5M in registered share capital, a €493M balance sheet total, and €987M in current project volume, with a Creditreform creditworthiness index of 154 ('very good'). The company has realized over 417,000 m² of gross floor area across residential and commercial projects. The legal entity was previously known as Cosimo Immobilienverwaltungs- und Handelsgesellschaft mbH and was rebranded to Cosimo Investment Group GmbH as part of a strategic repositioning toward an integrated full-lifecycle real estate platform.
