Postman Secures $225 Million in Funding Round to Continue to Grow API Ecosystems

Postman, a leading API platform, announced it has secured $225 million in a Series D round, enabling the company to expand its teams and continue to invest in its community of developers across the globe, support students through innovative API literacy programs, and contribute toward open source projects to foster a strong and thriving API ecosystem.

This latest funding round places the company’s valuation at $5.6 billion. The round was led by existing investor, New York-based global private equity and venture capital firm Insight Partners, and joined by new investors Coatue, Battery Ventures, and BOND, along with existing investors CRV and Nexus Venture Partners. In addition, DoorDash product leader Gokul Rajaram and Freshworks founder Girish Mathrubootham have also joined as individual investors. The company has now raised more than $430 million across four rounds.

Postman will also use the Series D capital to expand its teams in the areas of sales, marketing, product, and engineering.

Postman continues to experience exponential growth, as APIs increasingly become the driving force for software development and business success in this decade.

Today, Postman has more than 17 million users and 500,000 organizations on its platform, making it home to the largest API community in the world.

Postman has added more than 300 employees across 13 countries since the beginning of 2020, more than doubling its headcount, as well as adding thousands of new customers to a customer base that includes 98% of the Fortune 500 and the likes of Salesforce, Stripe, Kroger, Cisco, PayPal, and Microsoft. The company recently announced that its Public API Network is now the largest API hub in the world, with more than 75,000 APIs shared on the network.

To support this rapid, global growth of APIs across all industries, Postman continues to release new capabilities at a fast pace, notably: Postman on the web, public workspaces, the Private API Network, the Public API Network, API security validations, OpenAPI validations, support for protocols like WebSockets and SOAP, user groups, and SCIM integration, along with hundreds of other improvements.

“We are thrilled to have the support of our community and customers who continue to propel us forward, and this new round of funding will help Postman dramatically increase the speed of that forward motion,” said Postman CEO and co-founder Abhinav Asthana. “We’re committed to helping developers who are building the future with APIs.”
