## Questions

### What were some notable portfolio companies for Three Arch?

Confirmed positions include TransEnterix, a robotic-surgery company that went public on the NYSE American exchange, and CardioNet, a wireless cardiac-monitoring business later acquired by BioTelemetry. The firm's broader portfolio included both FDA-regulated device companies and health-IT platforms sold to hospital systems.

### Does Three Arch Partners still actively invest?

No. After raising a fourth fund of $375 million in 2002 and an initial close on a fifth fund in 2010, the partnership decided not to raise additional committed capital and shifted to managing out the remaining portfolio. By the mid-2010s, the founding partners had separated into new ventures.

### How did Three Arch Partners integrate clinical expertise into its investment process?

The firm recruited practicing physicians and hospital executives as formal venture partners, embedding clinical-workflow knowledge into sourcing, diligence, and board-level guidance. This operating-room perspective gave the partnership an information advantage when evaluating medical-device and health-IT companies, distinguishing it from firms that relied primarily on PhDs, consultants, or career investors.

### What geographic regions did Three Arch focus on?

The partnership concentrated its investments in US-based healthcare companies, with additional deal activity in Western Europe, particularly Germany and the United Kingdom. The San Mateo headquarters placed the firm within the Sand Hill Road venture ecosystem, facilitating syndication with other healthcare-focused funds.
