The company's core offerings include In-Patient Services for early-phase clinical trials—including Phase I and first-in-human studies—and Phase II-IV trial execution across therapeutic areas including cardiometabolic, oncology, neuroscience, and infectious disease/vaccines. Differentiated capabilities include purpose-built in-patient facilities for complex early-phase research, a 400,000+ patient database enabling recruitment from underrepresented populations, and a multi-site wholly-owned model that supports consistent study delivery.

Revenue is generated through B2B professional services contracts with pharmaceutical sponsors and CROs, with quote-based pricing that is not publicly disclosed. The go-to-market combines enterprise field sales targeting sponsors/CROs with a direct-to-consumer patient recruitment funnel via a website-based "Find a Study Near Me" tool. Customer relationships are anchored on enterprise pharma clients, with disclosed logos including Cassava Sciences for CNS/Alzheimer's trials. Co-founder and CEO Ana T. Marquez leads the company.
