Windjammer Capital Investors LLC

What Windjammer Capital Investors LLC does

Windjammer Capital Investors LLC is a Newport Beach, California-based private equity firm founded in 1990 that makes control equity investments in North American middle-market businesses, typically deploying $50M-$200M of equity per platform in companies with $8M-$50M of EBITDA. The firm targets three core verticals — advanced manufacturing, specialty distribution, and business services — and pursues a buy-and-build strategy that pairs each platform with strategic add-on acquisitions (over 100 add-ons completed) to build scale and market position.

The firm manages a series of senior equity funds with committed capital from a diversified institutional LP base comprising U.S. state and city pension plans, corporate pension programs, global PE fund-of-funds, European government institutions, insurance companies, endowments, and large family offices. Fund sizes have grown across vintages from $574M (Fund III, 2004) to $726M (Fund IV, 2013) to $870M (Fund V, 2018) to $1.3B (Fund VI, 2024), with cumulative commitments exceeding $2B since 2006. Windjammer has completed more than 50 platform investments over its history and partnered with management teams at companies including Hilco Vision, Heritage Foodservice Group, Mission Critical Electronics, Vital Records Control, JWC Environmental, Advanced Instruments, Hermetic Solutions Group, and Bio X Cell.

Revenue is generated through conventional private equity fund management economics — management fees on committed/invested capital plus carried interest on realizations — and the firm maintains two offices (Newport Beach, CA and Waltham, MA) staffed by a team of Managing Principals, Managing Directors, operating partners, and strategic operating consultants. The firm is SEC-registered as an investment adviser and supports portfolio companies with operational improvements, new product initiatives, market expansion, and targeted add-on acquisition programs.
