Granahan Investment Management

Portfolio management is led by CEO Jane White, who has been with the firm since the 1990s. The research team operates with sector analysts building proprietary models on each holding, and stock selection is committee-driven rather than centralized under a single star manager. John Granahan, the founder, remains involved in a board-level capacity but day-to-day portfolio decisions rest with White and the senior investment team.

The firm uses a bottom-up, fundamentals-driven process that emphasizes direct management meetings and proprietary earnings models. Analysts cover specific technology and healthcare subsectors, building expertise over multi-decade tenures. Granahan does not rely on sell-side research as a primary input and actively avoids stocks that are widely covered or consensus-owned among growth managers.

The firm generally avoids sectors where revenue growth is tied to commodity prices, regulated utility returns, or speculative biotech without approved products. Financials, energy, materials, and most consumer discretionary segments also fall outside the team's research coverage. Granahan's circle of competence remains firmly within enterprise software, applied AI, industrial technology, and healthcare equipment and services.

The firm offers its small-cap growth strategy through commingled mutual funds, collective investment trusts, and institutional separate accounts — but it does not operate a co-investment platform or club-deal structure. Separate account terms are negotiated directly with large institutional allocators and are not publicly disclosed.
