Hein Park Capital Management

Michael Hein is the founder and portfolio manager responsible for all investment decisions. Hein previously worked at D.E. Shaw, where he focused on technology and media equities, building the fundamental research discipline that defines Hein Park's concentrated long/short approach.

The firm runs a concentrated long/short equity strategy centered on small- and mid-cap companies in the TMT (technology, media, telecommunications) and consumer sectors. The approach relies on deep fundamental analysis to find businesses whose operational performance is mispriced by the market.

The firm's mandate is publicly traded equities. There is no indication of private company, venture, or direct-investment activity. The strategy is built around liquidity and price discovery in public markets, consistent with a traditional hedge fund structure.

The firm runs a concentrated book, typical of fundamental long/short equity managers operating in small- and mid-cap universes. Confirmed positions include T-Mobile US and Charter Communications, suggesting a preference for structurally advantaged businesses with recurring revenue models. Exact position counts are not publicly disclosed.

Hein Park's edge derives from founder Michael Hein's analytic training at D.E. Shaw, applied to a market segment where many large platforms have outgrown their ability to deploy capital efficiently. The firm's small- and mid-cap focus means it competes in a less crowded analytical field, where fundamental diligence still generates alpha.
