Accessible APIs empower entire companies to operate efficiently and we urge everyone to move to an API based workflow system. And anyone who can benefit from APIs, can benefit from Postman. For us, Postman became the contract between operations and engineering, and created a company unified around APIs.

Postman – the contract between operations and engineering at Coursera

Postman has supercharged our regression testing. We would have never caught some of the bugs we did if we did not have the testing suite set up. Using Postman has resulted in reducing a week’s worth of regression testing work to one to two days doable by two people instead of seven or more. Any company that works with APIs and wants to be efficient and lean needs this product.

EnergyCap and Modern QA Testing

At Box, Postman is a delightful tool for developers and also an educational tool that my colleagues and I use to ramp up on different aspect of our API using Collections. We use it for everything from post-sprint demos to platform discussions with customers. I know I owe some of my success as a senior sales engineer to Postman.
