Opkit was founded in summer 2021 by Sherwood Callaway and Justin Ko, two software engineers with a personal connection to the healthcare industry and a shared vision for improving it.
Sherwood and Justin met in early 2019 while working as early employees of Brex, the $12b financial technology startup, where together they built "Cash", a business bank account product.
Sherwood, the son of an orthopedic surgeon, grew up around the business of healthcare and was all-too-familiar with its inefficiencies. He convinced Justin to join him in creating a software product that would streamline administrative workflows for healthcare providers, starting with accepting insurance.
In July 2021, Opkit participated in Y Combinator, a leading startup accelerator.
