Waystar Holding Corp.
A maker of cloud software that handles the billing and payment side of healthcare. Its platform lets hospitals, clinics, and physician groups submit insurance claims, track their status, and collect patient payments more smoothly. The company was formed in 2017 when two healthcare tech firms, Navicure and ZirMed, merged, then took the name Waystar in 2018 — a nod to a "guiding star" meant to help providers find their way through the maze of medical billing.
