Granahan Investment Management is an independent, 100% employee-owned firm, that was founded in 1985 by investment professionals with a passion for small capitalization equity investing. The three founding principals, Jack Granahan, Gary Hatton and Jane White, remain committed to the smaller cap area of the market and have dedicated their investment expertise to serving large U.S. institutional clients.

Granahan utilizes extensive hands-on research to uncover and invest in high-quality, fast growing companies under $2.5 billion in market capitalization. One of the key factors to success in this area of the market is the experience of the investment team and their ability to use a generalist approach while following specific sectors of the market. Visits to companies, and meetings with the managements, are integral to the investment process and provide valuable insights to both the individual companies and the respective industry.

The firm has grown to over $3 billion in assets under management and the investment team has grown accordingly. During its history, the firm has had no turnover in its portfolio management team.
