Hi. We're Infinitus. We're a team of ex-Googlers, startup veterans, and industry experts on a mission to build AI that improves how Americans get access to critical specialty medications. Our purpose-built AI system automates phone calls to insurance companies, pharmacy benefit managers, and pharmacies to make the business of caring for people less "business," more "people."

Our approach combines multi-model/multimodal AI, human-in-the-loop machine learning, and an extensive knowledge graph to conduct accurate, compliant, autonomous conversations between organizations. Since Infinitus was founded over five years ago, we’ve automated over 3 million calls, processed more than 42 million minutes of audio, and saved the US healthcare system thousands of hours.

We’ve raised $102.9M from the best venture capitalists and many industry leaders such as Kleiner Perkins, Coatue Management, Google Ventures, a16z and Andreessen Horowitz. If you're looking to join a dynamic team at the forefront of AI and health tech, and you’re ready to challenge "how it's always been done," we want to meet you.
