Kopion Asset Management

Kopion runs a deliberately concentrated book of 20 to 30 small- and mid-cap names, held for five to seven years on average. This stands in contrast to the typical small-cap manager who diversifies across 80 to 120 positions as a volatility-management tool. Position sizing is conviction-weighted, not benchmark-relative.

The firm gravitates toward knowledge-economy compounders with high returns on invested capital and insider-aligned management. Recurring sector exposures include enterprise software, digital health, fintech, and cybersecurity. The team avoids capital-intensive industrials and commodity-reliant businesses that lack pricing power.

Kopion runs a direct, long-only public equity strategy. The firm does not operate as a fund of funds, nor does it allocate to external managers. All capital is deployed into single-name common stocks selected through bottom-up fundamental research.

Tom Plumb serves as portfolio manager and is the central decision-maker. He previously spent a decade at William Blair, where he developed the concentrated small-cap approach that would become Kopion's defining architecture. The firm maintains a lean team structure without investment committees that dilute accountability.

Kopion is an independent boutique with no parent organization. It does not operate a registered philanthropic foundation, a real-asset arm, or a separate private-placement vehicle. All client capital runs through the single concentrated equity strategy.
