Built by people who have scaled technology, treated patients, and lived the problem.

Serial technology founder and inventor with 100+ patent contributions across AI, computer vision, biometrics and health. Călin has spent more than 14 years building intelligent systems and technology companies from zero to scale.

He co-founded and built VAHA, where he served as CTO, through its acquisition by Bioniq, and previously led engineering and product organizations across consumer technology and digital health.

At NostraBiome, Călin leads the development of LIFE OS: a continuously learning system designed to understand human biological state from longitudinal clinical, molecular, behavioral and sensor data, and learn from how that state changes in response to interventions.

His conviction that biology needs to be understood as a dynamic system rather than a collection of snapshots also comes from personal experience navigating complex chronic disease.

Technology leader with deep experience building consumer products, intelligent systems and scalable health platforms. Before NostraBiome, Valerio held senior engineering roles across VAHA and Bioniq, helping build technology at the intersection of software, hardware and personalized health.

His work spans mobile platforms, distributed systems, data infrastructure and high-quality consumer experiences, including products recognized by Apple.

At NostraBiome, Valerio leads the technology behind LIFE OS: the infrastructure that continuously integrates biological, clinical, behavioral and sensor signals into a persistent representation of each patient.

His focus is turning extremely complex biological intelligence into infrastructure that can operate continuously and products that remain simple enough to use every day.

Practicing oncologist and ESMO member bringing clinical medicine directly into the development of LIFE OS. Dr. Radu works at the intersection of oncology, precision medicine and translational research, with direct experience treating patients whose biological response to disease and therapy can change rapidly.

At NostraBiome, he leads clinical strategy, medical validation and the translation of biological models into clinically meaningful interventions.

His work ensures LIFE OS is built around the realities of medicine: heterogeneous patients, incomplete information, changing biological states and the need to understand not only what is happening, but how an individual responds over time.
