Marlborough provides an integrated portfolio of transformational services that helps private equity firms and venture capitalists address the strategic challenges, operational dysfunction, and capitalization issues in their portfolio companies.

We also work with these firms to evaluate marginal investment opportunities and identify sale or merger opportunities. We use a proprietary methodology and a proven set of analytics, diagnostics, and development tools that help companies get up, get going, and get better.

Our partners are entrepreneurs who have founded companies, raised or managed hundreds of millions of dollars of capital in seed, growth, and mezzanine financings, had successful IPOs, and managed M&A processes from both the buy and sell sides.
