Sterling Investment Partners Advisers

Sterling makes control equity investments in North American middle-market companies within distribution, business services, and light manufacturing. The firm targets businesses with $10 million to $50 million in EBITDA and structures transactions as buyouts, often acquiring founder-owned or family-held companies where the selling owners retain a meaningful equity stake post-close. Sterling focuses on fragmented industries where professionalizing operations and pursuing add-on acquisitions can build a scaled platform.

Sterling concentrates on three adjacent verticals: distribution, business services, and light manufacturing. Within distribution, the firm has invested in value-added and route-based models. In business services, its portfolio has included facilities services and equipment rental. The firm explicitly avoids sectors outside these lanes, such as healthcare, technology, or energy, and does not pursue growth-stage venture investments or minority positions.

Sterling sources proprietary deal flow through a combination of long-standing intermediary relationships, industry-specific broker networks, and direct outreach to founder-owners in its target sectors. Because the firm has operated in the same verticals for over two decades, its sourcing model benefits from repeat interactions with business owners and advisors who know the firm's investment parameters and close rate, reducing the volume of auction processes it needs to participate in.

Sterling Investment Partners is structured as a traditional institutional private equity firm, not a family office. It raises capital from external limited partners — including pension funds, endowments, and fund-of-funds — across successive blind-pool funds. The partnership model includes a general partner commitment from the firm's principals alongside the institutional capital it manages.

Sterling typically holds portfolio companies for four to seven years, consistent with standard private equity fund cycles. Value creation centers on three levers: professionalizing management teams and governance, executing a deliberate add-on acquisition strategy to build scale within a fragmented industry, and investing in technology or operational infrastructure that a founder-owned business could not fund independently. The firm does not rely on financial engineering or aggressive leverage as a primary return driver.
