Media Ventures
Dirk Ströer’s Media Ventures invests permanent capital in German digital media, adtech, and consumer internet companies from its Cologne base.
Media Ventures
Media Ventures was founded in 1998 by Dirk Ströer, whose family controls Ströer Media AG, the German out-of-home advertising leader. Ströer launched early web portals such as neu.de and weg.de before formalizing the investment office. Today the firm operates from Beethovenstraße in Cologne, with an additional office in Düsseldorf housing portfolio company E2Ma GmbH. The firm blends venture investing with a services-heavy holding-company structure. Its portfolio spans digital media (c-date, Yasni), adtech (exactag, TPNG, Global Group), consumer internet (Spotted, FooBoo, HOCCER Messenger), healthtech (DiaMonTech), and real estate through its Property Ventures arm. Stage coverage is broad — from seed (merkando, 123FAHRSCHULE) to mature companies (dimensional, Global Group) — but the common thread is a preference for German-language markets. Co-investors on specific deals have included HTGF, Index Growth, and Voyager. The firm explicitly offers portfolio companies shared services in controlling, legal, personnel, and IT. Stefan Petter became Managing Director in February 2018, overseeing finance, legal, and investee controlling. The team remains deliberately lean; Dr. Katrin Schaal, a trained company-law specialist, has served as in-house counsel since 2008. Media Ventures does not disclose total assets, but the portfolio lists at least 18 active platform investments. In early 2016 the firm established a dedicated real estate arm, Property Ventures, to pursue direct property projects across Germany. Media Ventures’ architecture differs from most European venture firms because it operates as a permanent-capital vehicle tethered to a founder’s operating business rather than as a fund manager. There is no fundraising cycle. The in-house services layer — accounting, controlling, IT — functions like a mini operating partner group, reducing administrative drag for early-stage companies. This structural setup means the firm can hold assets indefinitely, without LP pressure to exit on a fund clock.

Frequently asked questions
Who makes investment decisions at Media Ventures?
Dirk Ströer, as Managing Shareholder, sets the strategic direction and likely retains final approval on investment decisions. Stefan Petter, appointed Managing Director in 2018, oversees transaction business and investee controlling. The firm’s website describes a collaborative approach where the team “would be happy to work with you,” but ultimate authority rests with Ströer given the permanent-capital structure.
Does Media Ventures raise external capital or invest off its own balance sheet?
Media Ventures does not market itself as a fund manager and shows no evidence of raising third-party LP capital. The firm describes itself as a private venture capital company whose capital originates from Dirk Ströer’s earlier exits and his family’s advertising business. This makes it a proprietary-capital vehicle, not a traditional venture fund.
How does Media Ventures support portfolio companies beyond writing a check?
The firm provides an in-house shared-services platform covering accounting, controlling, IT, legal, and personnel — a structure its website calls “unique.” Founders are promised relief from administrative burdens so they can focus on product and growth. This operator-heavy model is core to the firm’s pitch, particularly for early-stage companies without their own back-office infrastructure.
What is Media Ventures’ relationship to Ströer Media AG?
Dirk Ströer sits on the Supervisory Board of Ströer Media AG and his family controls the publicly listed out-of-home advertising company. Media Ventures GmbH is a legally separate entity, but the wealth that capitalizes it originated from Ströer’s early career building digital and outdoor advertising businesses within his father’s group. The two entities operate independently in their day-to-day activities.
Does Media Ventures invest outside Germany?
The firm concentrates on German-speaking Europe, with the portfolio dominated by German-headquartered companies. Some holdings, such as the dating platform c-date with 40 million users globally, have international customer bases. The real estate arm, Property Ventures, explicitly focuses on projects throughout Germany.
Which sectors does Media Ventures explicitly avoid?
Media Ventures states its focus is “not industry-dependent,” but the portfolio reveals no exposure to deep tech, hardware, biotech, or energy. The firm gravitates toward businesses where its in-house digital marketing, legal, and controlling services add immediate value — which in practice means internet platforms, adtech, consumer apps, and media.
How does Media Ventures handle exits given its permanent-capital structure?
Because the firm does not manage a fund with a fixed life, it faces no structural deadline to exit positions. Portfolio companies like dimensional (held since 2012) and Global Group (held since 2011) demonstrate multi-year holding periods. The firm does not discuss exit strategy publicly, a posture consistent with indefinite-hold permanent capital.
