Binkey
Binkey is a Washington, DC fintech that lets online merchants accept pre-tax health benefit dollars - FSA, HSA, and related accounts - as payment at checkout. Its AI-powered engine classifies products at the SKU level to determine IRS eligibility in real time, automates claim filing and reimbursement, and routes funds through developer-friendly APIs. Products span Binkey Pay (checkout acceptance), FSA + HSA Rewind (recovering unused benefit dollars from past purchases), and Binkey Vision (out-of-network vision reimbursement). The company raised $3.3M in seed funding in 2023.

Obiaku Ohiaeri Hill is the founder and CEO of Binkey, a Washington, DC fintech that turns FSA and HSA accounts into a checkout button. After years inside healthcare's machinery as a scientist, a McKinsey expert, and a product VP, she built an API-enabled payment service that lets merchants accept pre-tax health dollars at the point of sale and auto-files the paperwork so customers stop forfeiting the money they already set aside. Binkey raised a $3.3M seed round in December 2023 led by Wellington Access Ventures and was selected for the Mastercard Start Path program.
