Infinx

Infinx, founded in 2012 by Sandeep and Jaideep Tandon and headquartered in San Jose, automates the front end of the revenue cycle: prior authorization, eligibility verification, benefits checks, and patient pay estimates. Its model pairs AI and automation with certified specialists who handle the exceptions software cannot close, so providers get finished authorizations rather than another work queue. The company grew up serving radiology and other imaging-heavy specialties where prior auth volume is punishing, and also offers AR recovery, denial management, and revenue integrity services. It connects to Epic, Cerner, athenahealth, eClinicalWorks, NextGen, and other systems through APIs, HL7, FHIR, and RPA.

More than 900 provider organizations across the US use Infinx, from hospitals and health systems to national imaging and laboratory networks. Reported funding totals about $186M, with Norwest Venture Partners a longtime backer and KKR taking a minority stake in May 2024. In April 2026 its revenue cycle and patient access platforms attained HITRUST i1 certification. For buyers, it competes as a full-service prior auth outcome vendor rather than a pure software license, which suits organizations that want the work done more than they want another tool.
