About Company

Phases uses AI to automate clinical trial operations, starting with patient recruitment. Our agent scans medical records and conducts human-like voice interviews to assess patient eligibility for clinical trials. Our vision is to run the entire clinical trial back-office with agents, getting drugs to market at a fraction of the time and cost it takes today.
