Help Build the Future of Healthcare AI

Hi! We’re Infinitus — the first trusted voice AI platform transforming healthcare.

Built by ex-Googlers, startup veterans, and industry pros, our AI boosts productivity, slashes admin burden, and creates new ways to support patients with chronic conditions. We scale connections between patients, payors, and providers — empowering care teams and improving health outcomes.
