Frequently asked questions

Who leads investment decisions at Main Capital Partners?

Charly Zwemstra, Founder and Managing Partner, leads the firm alongside Managing Partner Pieter van Bodegraven. Investment decisions are made by the firm's partnership, which includes a team of sector-specialist partners managing deal sourcing and portfolio oversight. The firm operates a partnership model with clear sector responsibility.

How does Main Capital Partners source proprietary deal flow?

Main Capital Partners sources deals through its deep network of software executives, advisors, and industry contacts across Northwestern Europe. The firm's exclusive focus on enterprise software and SaaS creates a reputation that attracts inbound opportunities. Targeted outreach to founder-owned software companies in the Benelux, DACH, and Nordics also generates proprietary deal flow.

Is Main Capital Partners structured as a single family office or a private equity firm?

Main Capital Partners is a dedicated private equity firm, not a family office. It manages institutional capital from pension funds, insurance companies, and endowments. The firm operates as a regulated investment manager with separate fund structures, not as an entity managing a single family's wealth.

What investment stages does Main Capital Partners typically target?

Main Capital Partners targets growth-stage and buyout investments in enterprise software companies, typically deploying €10 million to €100 million per deal. The firm provides expansion capital for scaling, as well as majority buyouts for mature software firms. It also has a separate growth fund, Main Capital Growth, for smaller investments (€2 million to €10 million).

Which sectors does Main Capital Partners explicitly avoid?

Main Capital Partners explicitly avoids non-software sectors, including hardware, biotech, clean tech, real estate, and financial services. The firm's mandate is exclusively enterprise software and SaaS, covering sub-sectors such as cybersecurity, digital health, fintech, and AI/ML. It does not invest in consumer software or hardware.

Does Main Capital Partners participate in fund commitments or only direct deals?

Main Capital Partners invests exclusively in direct private equity deals, not in fund-of-funds or third-party fund commitments. The firm controls its investments directly, taking board seats and actively working with portfolio company management. Its co-investment vehicle allows select institutional partners to participate in larger transactions alongside the main fund.

Where does the underlying wealth come from for Main Capital Partners?

Main Capital Partners manages institutional capital, not a single-family fortune. The firm's limited partners include pension funds, insurance companies, and endowments across Europe and North America. The firm's own principals, including Charly Zwemstra, have co-invested significant personal capital into the funds alongside institutional investors.
