JEMS Development Editor Mike Brown interviews Hannah Herbst, founder and CEO of Golden Hour Medical, about a compact, automatic tourniquet designed to guide anyone through life‑saving hemorrhage control. The device uses audio‑visual prompts and a simple three‑step interface to let a bystander or first responder apply, monitor, and adjust pressure on arm or leg wounds. It initially inflates to 300 mmHg and can be increased in roughly 20 mmHg increments; an internal sensor monitors pulse absence and informs reassessment. The cuff detaches for multi‑patient use, and the unit recharges via USB‑C — batteries last about two years between charges with monthly status updates. Golden Hour pairs the product with online training and a small trauma first‑aid kit.
