Medicine’s blind spot

Long COVID, ME/CFS, POTS, and other complex chronic conditions affect millions of patients, causing a wide range of debilitating symptoms, including fatigue, brain fog, and chronic pain.

Despite decades of efforts, promising therapies have struggled to demonstrate efficacy across diverse patient populations in clinical trials, leaving few validated treatments.

Instead, clinicians are left trying different off-label treatments until they find what works best for each patient.

Our platform

We’re building a clinically integrated platform that combines real-world patient data and advanced diagnostics to improve care for patients with complex chronic conditions today and lay the foundation for tomorrow’s breakthrough treatments.
