Mertesacker Vermögensverwaltungs
Mertesacker Vermögensverwaltungs was founded in 2013 to manage the capital generated by Per Mertesacker's elite playing career. The firm is run day-to-day by his brother Timo Mertesacker and business partner Timo Kosien, both of whom serve as Managing Directors. Wealth management here is a direct extension of the family's local roots — the office's core is a collection of seven controlled subsidiaries including CP Immobilien, Mertrago Balearen, and modular-construction specialist Sturm & Drang Projekt, which together give it an operational footprint that blurs the line between family office and regional developer. The investment strategy is anchored in real estate, with a project pipeline that spans multi-family buildings in Hannover's Döhren and List districts, row houses in Pattensen, and a series of luxury finca projects in Mallorca locations like Santanyí and Portocolom. Alongside the property book, the firm makes direct startup investments at the seed stage through SPVs. Its disclosed venture focuses include ClimateTech, PropTech, and Sports & Wellness — areas that map directly onto the family's public identity and operating expertise. Geographic exposure concentrates in Lower Saxony and the Balearic Islands. The firm maintains a lean team structure with specialists in finance, real estate, and digital marketing, and has recently expanded hiring to support on-site construction roles in Mallorca. In early 2024, the affiliated Per Mertesacker Stiftung received the SPOBIS Sustainability in Sports award, reflecting the foundation's central role in the overall structure — it currently supports 150 children in the Hannover region through a ten-year program combining academics and football training. While no external AUM is reported, the office's member associations, including BinBau e.V., signal an active posture in Germany's sustainable-building policy network. What distinguishes this office structurally is its status as an operating company as much as an asset manager. Unlike family offices that allocate third-party capital across funds, Mertesacker's deployment is largely absorbed by its own controlled subsidiaries — specifically the modular housing venture Sturm & Drang Projekt, which uses serial construction to produce energy-positive affordable housing. This design means the family directly captures development margins and construction profits, then recycles them into the grant-making activities of its philanthropic foundation, creating a closed-loop model between commercial real estate and social programming.

Frequently asked questions
Who runs investment decisions at Mertesacker Vermögensverwaltungs?
Day-to-day management sits with Timo Mertesacker and Timo Kosien, both listed as Managing Directors on the firm's website. Timo Mertesacker handles financing and asset allocation, while Timo Kosien leads real estate acquisition and project development. Per Mertesacker serves as founder and provides strategic oversight but is not involved in daily operations, given his role managing Arsenal's academy.
How is Mertesacker Vermögensverwaltungs structured — is it a pure family office or an operating business?
It operates as a hybrid. The core is the multi-family office Mertesacker Vermögensverwaltungs GmbH, but the group directly controls seven subsidiaries: CP Immobilien, P4P, Mertrago Balearen, KMH, Kurt Gruppe, Sturm & Drang Projekt, and back 2 future. These are active operating companies involved in real estate development, construction, and proptech — not passive holding vehicles — making the office function as a holding company with an investment arm.
Does Mertesacker invest in startups, and if so, at what stage?
Yes, the firm makes direct seed-stage startup investments through SPVs, according to its profile. Sector focuses include ClimateTech, PropTech, EdTech, Media & Entertainment, and Sports & Wellness. The venture practice appears to be discretionary and tied to the family's personal interests — there is no evidence of a formalized fund structure or external Limited Partners.
What is the firm's real estate exposure on Mallorca?
The firm operates a dedicated Mallorca subsidiary, Mertrago Balearen S.L., which has completed multiple projects including Finca Kaderschmiede, Finca Römergut, Finca Tortuga, and the Kapitänshaus renovation in Portixol. The portfolio mixes luxury finca developments and, notably, social housing projects — in 2024 the office began hiring construction crews directly for new Mallorca-based work.
How is the Per Mertesacker Stiftung integrated into the family office?
The foundation is not a separate grant-making vehicle — the firm describes it as the 'heart' of the entire office. It currently supports 150 disadvantaged children in Hannover through a ten-year program of academic tutoring and football training, funded directly by the family's commercial activities. The foundation's prominence means the real estate and venture practices ultimately serve as funding engines for this philanthropic mission.
Does Mertesacker Vermögensverwaltungs participate in fund commitments or only direct deals?
The firm's known deployment is entirely direct — it operates its own real estate projects and makes direct startup investments through SPVs. There is no public evidence of commitments to third-party private equity or venture capital funds. This hands-on, operator-heavy approach contrasts with the diversified fund-of-funds model common among German multi-family offices.
What is the firm's link to modular construction and affordable housing?
Through its subsidiary Sturm & Drang Projekt GmbH, the firm develops multi-story residential buildings using serial modular construction, a method it claims reduces costs, energy consumption, and build time. The subsidiary produces energy-positive affordable housing in the Hannover region, directly executing the office's stated ESG goals without relying on third-party developers.
