Marlborough provides an integrated portfolio of transformational services that helps CEOs, boards, and management teams address the strategic challenges, operational dysfunction, and capitalization issues that create barriers to revenue and profit growth.

We also work with venture capitalists and private equity 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 invested nearly $500M of capital in seed, growth, and mezzanine financings, had successful IPOs, and managed M&A processes from both the buy and sell sides.
