Stonebridge Equity Partners

What Stonebridge Equity Partners does

Stonebridge Equity Partners, a business name of StoneBridge Merchant Capital Corp., is a Calgary-based private equity firm co-founded in 1996 by Rod Maxwell, Gary Lang, and Michael Lang, and joined in 2017 by Managing Director Russ Andrew. The firm invests its own capital in established private companies — typically those with revenues above $15 million and EBITDA above $2 million — with a particular focus on Western Canadian family-, entrepreneur-, and owner-operator-owned businesses. Its core offerings are management buyout financing, buyouts of inactive minority shareholders, growth and acquisition capital, and partnership structures designed for eventual sale.

The firm operates no proprietary technology product; its platform is a partner-led investment model in which each of the four partners takes direct, personal stakes and serves on portfolio company boards. Support services provided alongside capital include senior management recruitment, financial modeling, market analysis, acquisition sourcing, bank and equity financing arrangements, and exit process management. Deal sourcing is relationship-driven, leveraging the partners' networks rather than any systematic marketing channel.

Stonebridge generates returns by building portfolio companies and exiting via strategic sale or IPO. Its disclosed track record includes ten or more successful exits, notably the 2001 sales of Messaging Direct to Transaction Systems Architects for $75 million and Avicenna Medica to KS Biomedix for $90 million, the 2000 TSX IPO of Dynetek Industries, and the 2011–2012 sales of Creative Door, Brews Supply, and Trydor to Overhead Door Corporation and WESCO Distribution. The longest-held active investment, Cathedral Energy Services (now ACT Energy Technologies), has been in the portfolio since 1999 and grown from roughly $1 million to over $500 million in revenue, with Managing Director Rod Maxwell serving as Executive Chairman.
