Hello Heart

What it is

Hello Heart is a preventive heart health platform built around a connected blood pressure monitor, a smart pill box, and a mobile app, trusted by more than 150 Fortune 500 and government employers. In October 2025 it launched Nia, described as the world's first AI heart health assistant: a guardrailed agent that helps members understand their data, manage medications and side effects, and know when to escalate to a clinician. The AI is wrapped in a development-time eval set, a real-time monitoring agent, and licensed pharmacists who can intervene.

Who it's for

Employers and members who want to shift heart health from reactive to preventive, and founders building regulated, high-stakes vertical AI where a wrong answer carries real consequences.

Why it's better

• •Nia ships behind a two-layer guardrail model: a development eval set, a production monitoring agent, and human pharmacists in the loop.
• •Built as a specialist, not a generalist, it redirects off-topic questions back to its mission instead of drifting.
• •Signal stacking layers blood pressure over time with medication and symptom data to create a moat no single reading can produce.
• •Trusted by more than 150 Fortune 500 and government employers, with a roadmap toward a symphony of coordinated specialist agents.
• •Frees the human visit for fear, reassurance, and context by absorbing the administrative friction that never needed a person.
