Granite Alpha Capital Management

Katherine O'Brien serves as Managing Partner and Chief Investment Officer and is responsible for all portfolio decisions. She previously worked at Farallon Capital Management, the $40 billion multi-strategy hedge fund, where she specialized in event-driven equity strategies before launching Granite Alpha in 2016. The firm operates as a single-manager investment adviser with a concentrated decision-making process.

Granite Alpha operates as an independent hedge fund manager rather than a co-investment club or platform, and its concentrated strategy is built around proprietary idea generation and execution. There is no public indication that the firm participates in co-investment arrangements alongside external general partners. The firm's focus remains on building high-conviction public-equity positions where its catalyst-driven framework provides an analytical edge independent of co-investor alignment.
