- Massive addressable base. Over 60M Americans are eligible to use HSA/FSA funds—yet most merchants don’t support HSA/FSA payments online.
- Low current usage = upside. Only a fraction of account holders spend HSA/FSA dollars on consumer wellness today, leaving room for brands who move first.
- Perfect for high-intent wellness ecommerce. Supplements, wearables, recovery tools, and more can be eligible when used to treat specific conditions.
- Medpaid connects the dots. Eligibility rules, LMNs, telemedicine, and HSA/FSA payments sit in one platform built for ecommerce.
