Choi & Park Investment.

Portfolio

Few positions. Each behind a real barrier.

We hold a concentrated book. A company earns a place when its advantage is structural — a clearance, a dataset, or an infrastructure position a competitor cannot replicate with capital alone.

Impulse UWB radar that measures heart rate, respiration, and movement continuously — without wearables or cameras. FDA-cleared since 2021, with deployments across 210+ correctional facilities, skilled nursing, behavioral health, and hospital pilots including Mayo Clinic.

Why we invested

A regulatory head start that compounds, a clinical outcome dataset that cannot be bought or scraped, and inbound licensing interest from four Tier-1 electronics manufacturers who tried to build the same capability internally and could not.

A note on selectivity

We publish only what we hold, and we hold only what we would underwrite again today. New positions are added deliberately.
