Granahan Investment Management (GIM) was founded in 1985 by investment professionals with a passion for small capitalization growth equity investing, and the sole purpose of providing high quality small cap portfolios to institutional investors and wealthy individuals. While the firm has grown and the small cap offerings have expanded, this remains the mission of GIM today.
The founding partners of the firm nurtured a culture that promotes collaboration and rewards performance. The investment team members are curious, purposeful investors with a dedication to bottom-up small company research. As a boutique investment firm, GIM has a close-knit team that works collaboratively while offering a healthy diversity of opinion.
GIM’s structure, including its lean technology-driven back office, allows us to focus the firm’s resources on the investment process and superior client service.
We believe the power of the individual grows exponentially through our process and team dynamics.
