About the company
Level Zero Health develops a biosensor platform for remote, continuous hormone monitoring. Its core product is a minimally invasive arm patch that uses DNA-based biosensors and microneedles to measure hormones such as estrogen, progesterone, cortisol, and testosterone in interstitial fluid. The patch attaches to the skin, accesses interstitial fluid with microneedles, and converts hormone levels into electronic signals sent to a connected system for real-time tracking integrated into clinical workflows. The company differentiates itself with continuous, real-time data from a wearable platform focused on women's health, validated at 98% accuracy in simulated clinical ranges, and pursuing FDA and CE approvals to enable IVF, menopause management, and testosterone replacement therapy applications. Its goal is to move hormone tracking from infrequent tests to continuous data streams to support better clinical decisions, with plans to expand into consumer and pharmaceutical markets.

Simplify's Take
What believers are saying
- April 2026 LinkedIn update said clinical-grade hormone measurement without blood draws works.
- February 2025 funding closed at $6.9 million from Redalpine, HAX, and EF.
- August 2026 reporting says major IVF clinics signed $3 million letters of intent.
What critics are saying
- Single-use intermittent patch needs FDA and CE clearance before 2026 revenue.
- Continuous wearable slips to 2028, leaving competitors time to capture clinics first.
- SPRIND backs seven rivals, including Biomarq Health and PHOEBE, in parallel.
What makes Level Zero Health unique
- DNA-based microneedle patch measures progesterone, estrogen, cortisol, and testosterone from interstitial fluid.
- SPRIND selected Level Zero Health in July 2026 for its €40 million challenge.
- CEO Ula Rustamova and CTO Irene Jia combine Palantir software and Philips devices.
