About COI Partners Capital Management

COI Partners Capital Management AG (originally registered August 2004 as EquiNet Venture Partners AG and renamed to its current designation August 2022) trades under the brand COI Partners and operates the German management entity COI Partners Deutschland GmbH alongside the Swiss-anchored group. The headquarters are in Frankfurt am Main with the broader group operating from Zurich, Frankfurt and Berlin. The original Co-Investor AG group brand was founded in 2001. The German AG was incorporated in 2004 and rebranded to COI Partners Capital Management AG in 2022. Assets under management are approximately €300 million as of the July 2022 first close of the COIP DACH Growth II SCSp fund (€120 million), with subsequent capital deployment through 2024 remaining around the €300 million scale. The structure is an independent growth-equity group organised around a Luxembourg SCSp fund vehicle supported by a German Capital-Management AG and Swiss operating entity. Two principal vehicles: the historic deal-by-deal co-investment platform anchored by entrepreneur LPs and the COIP DACH Growth II SCSp fund. The group is a BVK member. The combined platform has executed over 110 initial and follow-on investments and 40 exits since inception.

Investment thesis

COI Partners pursues a growth equity strategy for established small and mid-sized companies in the DACH region with proven business models and ideally positive cashflow. The firm blends a discretionary fund with a deal-by-deal co-investment vehicle, allowing larger ticket flexibility per transaction and giving its limited partner base direct exposure to selected deals. The firm positions itself as an entrepreneur-backed investor (entrepreneurs finance entrepreneurs), emphasising operational rather than purely financial support. Sectors are sector-agnostic with historical concentration across IT and software, consumer and retail, life sciences, technology and industrials. The portfolio spans both classical mid-market industrials and high-growth digital businesses. Geography is focused exclusively on the DACH region (Germany, Austria, Switzerland), targeting companies operating in or expanding from German-speaking markets. Ticket size is €15 to €30 million per company in initial and follow-on investments, drawing on the SCSp fund and matching co-investment commitments from the LP network. The limited partner base is predominantly DACH-based with a network of entrepreneurs and family offices alongside institutional limited partners. Value creation operates through long-duration partnership with hands-on engagement, growth capital for international expansion, follow-on capacity through the deal-by-deal vehicle and access to an entrepreneur network spanning over 20 years.
