Weston Presidio Capital

Michael Cronin, Michael Lazarus and Mark Bono have served as managing partners since the firm's founding in 1991. All three were principals in the buyout of Bank of Boston's venture portfolio that created the firm, and they operated as a collective investment committee rather than the traditional single-CIO model common among middle-market buyout shops. Investment decisions required consensus across the partnership.

The firm has not publicly announced a new fund since closing Fund V in 2005. By the mid-2010s, Weston Presidio transitioned away from active fundraising and new platform investments, moving to a portfolio-management posture typical of a mature fund family nearing the end of its natural investment lifecycle. No successor vehicle or rebranded platform has been launched by the managing partners.

The firm avoided early-stage venture capital, real estate and financial services, concentrating instead on business services, specialty manufacturing, consumer products and healthcare services. This generalist-but-disciplined approach reflected a belief that middle-market operational improvement opportunities were more predictable in industries with tangible assets, recurring revenue and fragmented competitive landscapes than in technology or regulated sectors.
