Locata is an AI referral management platform for Primary Care. We deploy AI agents to automate every step of the referral process that back-office staff face daily, from submitting prior authorizations to broadcasting updates and following up with patients. This frees up staff to focus on patient care. Primary care back-offices are severely understaffed and overburdened by administrative work associated with referrals. Additionally, patients suffer navigating the complex referral process, which can have disastrous health effects if they don’t get the care they need. These factors point to a glaring gap in the system—where out of over 100 million specialist referrals issued annually in the US, only half are actually completed. Locata is tackling this problem head-on, saving administrative staff hours each week and ensuring that the referral process goes as smoothly as possible for patients and their providers.

Cenote builds AI sales reps for online health clinics and deploys them for abandoned-cart and win-back campaigns. Today, digital and telehealth clinics rely on generic text blasts or human follow-up for speed-to-lead and customer reactivation. Since the lead has often gone cold and the outreach isn’t personalized, conversion is frequently below 1%. Cenote’s AI agents reach out immediately, communicate on the patient’s preferred schedule, and operate across channels—dramatically increasing conversion rates and unlocking revenue that otherwise goes unrealized.

Mecha Health builds foundation models to automate x-ray analysis for radiologists. We take medical images and process them using proprietary models to produce accurate draft medical reports. Our first model was built in less than two months, and beat Microsoft, Google, and OpenAI on clinical accuracy metrics.
