Market Opportunity

Tap into a $147B+ HSA/FSA market that’s still underused

Millions of HSA and FSA account holders have pre-tax dollars earmarked for health and wellness. Medpaid helps ecommerce brands capture that spend with compliant HSA/FSA payments and telemedicine support.

HSA Accounts ~39M
FSA Accounts ~3.2M
HSA Assets ≈$147B
FSA Assets ≈$30B
  • 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.
