Cofactor AI was founded in August 2023 by Adi Tantravahi and CTO Juan Sebastian Lozano in Chicago, after Tantravahi watched his aunt, a physician and medical director, absorb the administrative weight of insurance claim denials. The company raised a $4 million seed round backed by Drive Capital and launched its denials-management platform publicly in late 2024.
The platform uses what the company describes as a medical-native foundation model to cross-reference clinical evidence, coding guidelines, and payer policies against a denied claim, then pinpoints the specific discrepancy an appeal needs to address. Agents built on top of that model draft the appeal letter, gather supporting documentation, and can verify eligibility, work that hospital billing staff would otherwise handle by hand, claim by claim.
Cofactor AI is built for hospital revenue cycle management teams and CFOs dealing with rising claim denial volume rather than individual clinicians or patients. Pricing is enterprise and not published, structured around a value-capture or subscription model, with the company pointing to a 3:1 return on investment as its pitch to health systems.
