Revenue model

1. Growth Equity Investment Returns: COI Partners generates returns through equity investments in growth-stage SMEs in the DACH region. Returns are realized through exit events (trade sales, IPOs, secondary transactions). The deal-by-deal model distributes proceeds to co-investors per exit event. Revenue is driven by capital appreciation and exit multiples on portfolio companies.

Core offering

COI Partners is a private growth equity investor that structures deal-by-deal direct equity investments in growth-stage SMEs in the German-speaking Mittelstand (DACH region). The firm typically deploys approximately €10–30 million of equity per transaction into profitable companies with turnover exceeding €10 million and growth above 10% per annum, and operates a co-investment platform enabling high-net-worth entrepreneurs to participate alongside COI Partners in curated direct investments.

Product overview

COI Partners is a pioneer in deal-by-deal growth equity investing in the DACH region since 2001. The company operates as a private equity firm offering direct equity investments in SMEs rather than a traditional technology product company. Their core offering consists of Growth Equity Investment Services for investors seeking direct private equity exposure, Capital Raising Services for growth-stage companies (with equity requirements of €10-30 million), and an Investor Network & Direct Investment Platform enabling co-investment opportunities in portfolio companies. COI Partners does not offer a unified software platform or consumer-facing tech products; instead, they provide investment management and advisory services with a partner-driven approach.
