Our Vision
for Greater Interoperability

In a world where the speed, accuracy, and accessibility of information can mean the difference between success and failure, the valuable data within our healthcare communities have remained trapped and siloed.

At Avaneer Health, we provide the connectivity to guide the healthcare industry into a new era of healthcare experiences: where data is shared, care can be accelerated, and solutions are developed together.

Innovation through Collaboration

Avaneer Health was founded by top industry leaders on a mission to unlock the full potential of healthcare by improving transparency and enhancing interoperability.

The founding partners included Aetna, a CVS Health company; Anthem; Cleveland Clinic; Health Care Service Corporation, a Mutual Legal Reserve Company (HCSC); The PNC Financial Services Group, Inc.; and Sentara Healthcare. Incorporated in 2020 as the Health Utility Network, we are now known as Avaneer Health. With continuing support from our partners and the biggest players across the healthcare space, we aim to play a key role in transforming how the healthcare industry operates to address consumers' needs more efficiently and effectively.
