About Virtusan

Virtusan is a digital health startup on a mission to simplify healthy habit-building. Our app empowers individuals to take control of their well-being through actionable tools and seamless access to personalized health data and insights.

We’re building a science-backed mobile platform that includes a variety of interactive tools—called “practices”—that users can mix and match to support sleep, stress reduction, physical health, and performance. These include guided meditations, breathing exercises, and biometric tracking. Our core product is shaped by a world-class advisory board and powered by a tight-knit, cross-functional team. To enhance this experience, we’ve developed the Virtusan Ring—a next-generation wearable that tracks key health metrics. The ring seamlessly integrates with the Virtusan app to provide real-time, personalized insights that help users make meaningful, measurable progress toward their wellness goals.
