From the AMINO website:
We work with private companies and public organizations who process and pay the country’s health insurance claims to get access to anonymized data.
We gather the records and stitch them together into the single best picture of what's happening in American health care for everyone to see. We integrate seamlessly with your insurance to guide people to the best in-network care and get upfront cost estimates. Plus, our HSA makes saving simple for your high deductible population.
