Background

Keith Dee is President of Osage Advisors, a Centerbrook, Connecticut-based M&A advisory firm focused on helping owners of privately held, family-owned, and closely held businesses sell their companies. Osage says Dee has more than 30 years of experience advising owners and families of midsize companies on M&A and capital transactions.

Before Osage, Dee began his career as a CPA and formed his own accounting firm. He later sold that practice and became Chief Financial Officer of The Great American BackRub Company, a public specialty retailer and wellness company based in New York. He subsequently served as President of Earmark, Inc., a New England-based manufacturing company.

Dee founded Osage Advisors in 2001 after, according to Osage’s own 25-year retrospective, identifying a gap between large investment banks and main-street business brokers: owner-focused M&A services for lower-middle-market, family-owned businesses. Osage says he launched the firm five weeks before September 11, 2001, later navigating the Great Recession and COVID-era disruption.

Dee earned a BS in accounting from Bryant University. Osage’s team page states that he holds Series 7, 63, 79, and 82 registrations as a representative of StillPoint Capital, LLC, Member FINRA/SIPC.

Investment Thesis & Focus

  • I found no verified public evidence that Dee is an active seed-stage angel investor; public sources describe him as an M&A advisor and banker, not a venture investor.
  • Osage’s stated client focus is sell-side advisory for family-owned and closely held companies with at least $5 million in annual revenue.
  • Osage’s process emphasizes senior-level, hands-on M&A guidance, broad buyer outreach, multiple qualified offers, and negotiating for both price and buyer fit.
  • The firm states: “We put YOU ahead of the transaction.”
  • Osage primarily represents sellers based in the Northeast, while running targeted outreach to strategic and financial buyers in the U.S. and internationally.
  • Dee’s sector experience spans manufacturing, business services, IT, healthcare, and distribution; recent Osage transaction categories include tech-enabled services, aerospace, contract manufacturing, business services, and healthcare.
