Flex is a financial technology company that enables health and wellness brands to accept HSA and FSA payments online. The company was founded to simplify a historically complex and restrictive checkout process, making it easier for merchants and consumers to use pre-tax health benefits at the point of sale.

Traditionally, HSA and FSA payments have been difficult to process outside of large retailers, often requiring customers to pay out of pocket and submit reimbursement paperwork. Flex addresses this challenge by providing infrastructure that verifies product eligibility in real time, processes split payments for eligible and non-eligible items, and can generate Letters of Medical Necessity directly at checkout.

Backed by investors including First Round Capital, Core VC, and Rethink Capital, Flex powers checkout experiences for leading brands such as Equinox, Dermstore, Therabody, and Ultrahuman. By unlocking access to an estimated $150 billion in annual HSA/FSA spending, Flex helps merchants increase revenue while making it easier for consumers to fully utilize their healthcare benefits.
