Roslyn grew up close to the operational reality of Army life — where readiness is not a slogan but a discipline. Years in teaching trained her to take complex things and make them understandable, calmly, for the people who need to act.

Zayra began with a simple, stubborn observation: the heart almost always changes gradually before it changes catastrophically. We have the sensors, the models and the clinical knowledge to see those changes. We just hadn’t built the system to take them seriously, calmly, at scale.

Zayra is that system — built by people who believe early visibility, governed interpretation and human triage belong together.
