From one person's pain to a mission for
500 million.

A decade of unanswered questions

NostraBiome was founded by Calin Popescu, a serial entrepreneur and inventor who endured over a decade of unresponsive Inflammatory Bowel Disease. Frustrated by the limited treatment options, he leveraged his technological expertise — the team members have collectively filed over 100 patents — to create a fundamentally new approach.

After extensive testing and analysis, he discovered correlations and patterns in the disease that allowed him to attack specific elements and gradually improve his symptoms. He realized that IBD — and chronic disease in general — requires a deeply personalized approach, tailored to the unique biological factors that influence each individual.

That insight became NostraBiome: a platform that doesn't just track symptoms, but models and understands them — using proprietary small biology models to restore immune state in real time.

Small biology models that change everything

We invented a new class of AI models — small biology models— designed specifically to understand the complex interactions between your microbiome, immune system, and overall health. Unlike general-purpose AI, these models are trained on biological signals unique to each condition.

This personalized approach significantly enhances the efficacy of therapies for conditions such as IBD, various cancers utilizing immunotherapy, weight management, fertility, and longevity — introducing a hyper-personalized step that dramatically increases treatment efficiency.
