Postman, the leading platform for API development, announced today that it has secured $150 million in a Series C investment round led by Insight Partners, a global venture capital and private equity firm. Insight Partners joins previous investors CRV and Nexus Venture Partners in this round.

APIs are the fundamental building blocks of all software in the world. Today’s complex software ecosystems make the rapid creation and seamless deployment of APIs an industry imperative. Used by more than 500,000 companies globally, the Postman API Platform helps them accelerate their pace and effectiveness of software development.

Postman is leading the shift to an API-first approach which means building APIs at the very beginning of the development cycle and collaborating closely between all stakeholders like product management, DevOps, and quality engineering.

According to Enterprise Strategy Group, companies using the Postman API Platform show vast improvements to API development, collaboration, and testing. These improvements include API development that’s five times faster, collaboration that’s ten times more effective, and the ability to find and fix bugs four times faster.

According to CEO and co-founder Abhinav Asthana, “Developers all over the world are rapidly transitioning from the code-first mindset to an API-first mindset with Postman being the center of this revolution.”
