Postman is an Indian-origin global software company that offers an API platform for developers to design, build, test, and collaborate on APIs. Over 30 million registered users and 500,000 organizations are using Postman. Postman also maintains the Postman API Network, a directory of over 100,000 public APIs that is listed as the world’s largest such collection. The company is headquartered in San Francisco and maintains additional offices in Tokyo and Bengaluru, where Postman was founded.

In August 2021, Postman raised a $225 million Series D round at a $5.6 billion valuation making it a unicorn company.

Postman started in 2012 in Bangalore as a side project of software engineer Abhinav Asthana, who wanted to simplify API testing while working at Yahoo Bangalore. He named his app Postman – a play on the API request “POST” – and offered it free in the Chrome Web Store. As the app's usage grew to 500,000 users with no marketing, Abhinav recruited former colleagues Ankit Sobti and Abhijit Kane to help create Postman, Inc. The three co-founders lead the company today, with Abhinav serving as CEO and Ankit as CTO.

In 2017, Postman moved its corporate headquarters from Bangalore to San Francisco.

In 2023, Postman announced it had acquired Akita, an API observability solution. In 2024, Postman acquired Orbit, a solution for building and managing developer communities.

Postman features include:

Postman v11 was released in May 2024. The update includes AI-powered features to help developers with API test generation, documentation, debugging, and data visualization. V11 also enables more users to share API collections with external partners.

Postman offers tiered pricing, ranging from free options for small teams to paid plans for larger companies and enterprises.
