Build the AI Layer Powering Healthcare Payments

R37 is an applied AI lab within R1. We harness the scale of R1’s network to deploy AI for smarter healthcare payments.

PhareOS: AI Built for Complex Revenue Workflows

Each patient encounter must be translated into the exact language insurers require. When processes run on fragmented systems and manual handoffs, meaning gets lost and delays follow.

Our Revenue Operating System unifies processes, reading the full record, applying payer rules and ensuring accurate translation.
