Gilder Gagnon Howe & Co.

Portfolio manager Arthur Howe Jr. has been the firm's most publicly associated investment decision-maker for over two decades. The firm operates as a partnership, with a small team of portfolio managers and analysts contributing to a single concentrated growth-equity strategy. The partnership structure means investment decisions are made collectively, though Howe is the named lead in external rankings (per Barron's, 2022).

The firm relies on proprietary fundamental research conducted by its in-house analyst team. Analysts build long-term revenue and earnings models through direct company engagement, including management meetings and industry conferences. Because the portfolio holds only 30 to 45 names and turnover is exceptionally low, idea generation is deliberately slow — the firm adds new positions infrequently and only after extended due diligence.

No. Gilder Gagnon Howe invests exclusively in publicly traded equities listed on US exchanges. The firm has no known private-equity, venture-capital, or real-asset vehicles. Its 'buy and hold' style can resemble private-investing patience, but the underlying securities are all traded on public markets.

The firm runs a concentrated growth-equity strategy with historically low single-digit annual turnover. Portfolio holdings typically number between 30 and 45 names. The focus is on companies with durable competitive advantages, predictable revenue growth, and expanding margins — a quality-growth philosophy applied with unusual patience and position-size conviction.

The firm historically grows through personal referral and has not marketed broadly to the public or institutional allocators. Its capacity-constrained model — running a single concentrated strategy — means asset growth can dilute portfolio performance, so the partnership has been selectively in taking on new client relationships. Prospective clients typically require a personal introduction.
