Summit Creek Advisors

Mark Thompson, the firm's founder and Chief Investment Officer, serves as the sole portfolio manager for the small-cap growth strategy. He is supported by a small team of research analysts, but all final buy and sell decisions rest with him. The firm has deliberately avoided a committee-based approach to maintain speed and accountability.

Summit Creek has a history of soft-closing its strategy to new investors when assets approach levels that could impair its ability to execute a concentrated small-cap mandate. The firm prioritizes strategy integrity and existing client outcomes over asset gathering, a posture reinforced by its lean operational structure and Thompson's role as sole decision-maker.

The firm invests exclusively in publicly traded US equities with a focus on small-cap growth companies. The strategy is long-only with no allocation to private equity, venture capital, or credit instruments. Public filings confirm a portfolio of common stocks with occasional small cash positions for liquidity management.

The portfolio typically holds between 30 and 40 names, reflecting a high-conviction approach. Individual position sizes are meaningful, and turnover is low because the investment thesis for each holding extends over multiple years. The firm concentrates on what it identifies as durable, franchise-quality businesses with long reinvestment runways.

Summit Creek does not invest in early-stage biotechnology, natural resource extraction, or highly regulated utilities. The firm has also historically avoided real estate investment trusts and companies with excessive financial leverage, preferring asset-light business models with predictable recurring revenue streams.
