The Sonic team collaborated closely with Sameday Health during the COVID-19 response to rapidly develop and scale their end-to-end booking flow. This flow became the company's core digital product, processing up to 40k bookings per day for tens of millions of patients, marking a significant milestone in their journey towards nationwide healthcare access.

Our Work

During the initial wave of COVID-19 response, time to market mattered enormously for Sameday Health. Sebastian, David, and the extended team rapidly scoped the infrastructure for the Sameday Health end-to-end booking flow, which turned into the company's core digital product. With strongly rising testing numbers, the technology system had to continuously be adjusted and extended, making it one of the most extensive technology products in terms of scale and revenue processed that our team has worked on to date.

Project Outline

"David, Sebastian and the team made a true impact at Sameday Health. We would not have been able to scale our technology systems as fast as we needed to without their product management and engineering. They built an infrastructure that processed millions of tests, including payments, in a matter of months. I am very grateful for their support of Sameday Health!"
