Overview
Postman makes a platform that software developers use to design, build, test, document and share APIs (application programming interfaces), the connections that let software systems talk to each other. Almost every modern app depends on APIs: a payment app calls a bank's API, a travel site calls airline APIs, and AI agents call APIs to take actions. Postman began as a simple tool for sending API requests and inspecting responses, and has grown into a collaboration platform used by tens of millions of developers and hundreds of thousands of organisations, including most large companies.
Abhinav Asthana, the CEO, Ankit Sobti and Abhijit Kane founded Postman. Asthana created it in 2012 as a side project, a Chrome extension to make his own API work easier while he was an engineer at Yahoo in Bangalore. It spread quickly through word of mouth, and the three founders incorporated the company in 2014. Postman later moved its headquarters to San Francisco while keeping a large engineering centre in Bangalore, and it is one of the best-known software companies with Indian founders.
Products
- API client: the core tool for sending requests, inspecting responses and debugging APIs.
- Workspaces and collaboration: shared collections, environments and documentation for teams.
- API testing and monitoring: automated tests and scheduled checks that APIs work as expected.
- API design and governance: tools for defining APIs with standards such as OpenAPI and enforcing rules across an organisation.
- Public API Network: a large directory where companies publish APIs for developers to discover.
- AI tools: an AI assistant, tools for building and testing AI agents and support for the Model Context Protocol, which lets AI models connect to APIs and data.
Funding
Postman raised early funding from Nexus Venture Partners and CRV. In July 2020 it raised a US$150 million Series C at a US$2 billion valuation, led by Insight Partners. In August 2021 it raised a US$225 million Series D at a US$5.6 billion valuation, again led by Insight Partners, with new investors Coatue, Battery Ventures and BOND, and returning investors CRV and Nexus. Total funding exceeded US$430 million. At the time, Postman said it had more than 17 million developers and 500,000 organisations using the platform. We haven't found a newer priced round, so the 2021 valuation should be treated as historical.
Business model
Postman uses a freemium model: individuals and small teams can use it free, while paid plans add collaboration, governance, security and administration features for teams and enterprises. Large companies sign enterprise contracts covering thousands of developers. The company doesn't publish revenue, so we show it as not disclosed.
Competition
Postman competes with API clients such as Insomnia (owned by Kong), Bruno and Hoppscotch; with API platforms from Kong, Apigee (Google) and MuleSoft (Salesforce), which focus more on API management and gateways; with SmartBear's Swagger tools for API design; and with developer platforms that add API testing features. Its advantages are its enormous user base, brand recognition among developers and broad feature set.

Why APIs matter even more in the AI era
AI agents don't just generate text; they take actions such as booking meetings, updating records and placing orders by calling APIs. That means APIs are becoming the main way AI systems interact with the software world. Companies need to design APIs that agents can understand, test how agents use them and monitor them for reliability and security. Postman has repositioned its platform around this shift, arguing that the API layer is where AI meets real business systems.
Who uses Postman
Postman's users include individual developers learning to work with APIs, engineering teams at startups, and large enterprises in banking, retail, telecoms and technology that maintain thousands of internal and external APIs. Quality assurance testers, technical writers and product managers also use it for documentation and testing.
Product-led growth
Postman is a classic example of product-led growth: a free, useful tool spreads among individual developers, who then bring it into their companies, where teams eventually pay for collaboration and enterprise features. This model keeps sales costs low and creates strong brand loyalty, but it requires a clear path from free usage to paid plans and careful balance between free and paid features.
Valuation context
Postman's US$5.6 billion valuation was set at the 2021 software boom. Public software multiples fell significantly afterwards, so a future round or IPO could value it differently depending on its revenue growth since then. Our guide to SaaS valuation multiples explains how investors compare software companies.
Risks
- Open-source alternatives: free, lightweight API clients attract developers who dislike account requirements or cloud sync.
- Monetisation: converting a huge free user base into paying customers is a constant challenge.
- Platform bundling: API management vendors and cloud providers may add similar features.
Questions for engineering teams
- How will you manage API standards and governance across teams?
- How do you test APIs automatically as part of your release process?
- How will AI agents discover and use your APIs safely?
Latest developments (October 2026)
