Who is Abhinav Asthana?
Abhinav Asthana is the Co-founder and CEO of Postman, an API development and collaboration platform. He co-founded Postman with Ankit Sobti and Abhijit Kane, with the company formally launching in 2014. What started as a side project for testing APIs grew into a platform used by more than 40 million people and 500,000 companies, according to Postman’s current materials.
Early Life and Education
Asthana developed an interest in software development early in his career and eventually moved toward building developer-focused products. His work has largely centred on solving practical problems faced by software engineers rather than creating technology for consumers.
His experience working directly with APIs became particularly important to the creation of Postman. Instead of treating API development as a specialised technical problem, he saw an opportunity to make the process easier for developers and teams.
Career Before Postman
Before founding Postman, Asthana worked at Yahoo! in Bangalore. His experience there exposed him to the challenges developers faced while working with APIs.
The problem was familiar to engineers. Testing APIs often required multiple tools and cumbersome workflows, making collaboration between developers difficult. Asthana began working on a simpler solution as a side project.
That project eventually became Postman.
How Postman Started
Postman began as an API testing tool created by Asthana to make working with APIs easier. The product gained traction among developers because it simplified the process of sending requests, testing responses and collaborating around APIs.
Asthana later joined forces with Ankit Sobti and Abhijit Kane, and Postman was formally launched in 2014.
The company expanded from a testing utility into a broader API development platform. Its products now cover API design, testing, documentation, collaboration and management, allowing teams to work across different stages of the API lifecycle.
Postman’s growth reflects a broader change in software development. APIs have become fundamental infrastructure for connecting applications, services and increasingly AI systems.
Funding History
| Round | Year | Amount | Lead Investors |
|---|---|---|---|
| Seed | 2016 | Not publicly disclosed | Nexus Venture Partners |
| Series A | 2019 | $7 million | Nexus Venture Partners |
| Series B | 2020 | $150 million | Insight Partners |
| Series C | 2021 | $225 million | Coatue |
Postman raised substantial venture funding as it expanded its developer platform. Its 2020 Series B valued the company at approximately $2 billion, while the 2021 Series C valued it at approximately $5.6 billion.
Revenue Growth and Recent Developments
| Fiscal Year | Revenue | Profit/Loss |
|---|---|---|
| Latest publicly disclosed | Not publicly disclosed | Not publicly disclosed |
Postman is privately held, so detailed current revenue and profit figures are not consistently publicly disclosed.
The company has continued expanding beyond traditional API testing. Its current strategy increasingly connects APIs with AI-native development and software agents.
In August 2026, Asthana announced Postman.ai, signalling a shift toward AI-native API development and tools designed for the emerging agentic software ecosystem.
Postman’s current materials report more than 40 million users and 500,000 companies on the platform, demonstrating the scale the company has achieved since its early developer-tool origins.
Public Recognition
Asthana has become a prominent figure in the developer-tools ecosystem through Postman’s growth and his public writing and speaking on APIs, AI-native development and software engineering.
His profile has increasingly expanded beyond API testing into discussions around how AI agents will interact with software and APIs.
Postman vs Competitors
| Company | Founded | Positioning |
|---|---|---|
| Postman | 2014 | API development and collaboration |
| Swagger | 2011 | API design and documentation |
| Insomnia | 2014 | API development and testing |
| Apidog | 2021 | API design, testing and development |
Postman’s advantage comes from the breadth of its platform and its large developer community. It has evolved beyond a simple API testing tool into a broader environment for designing, testing, documenting and collaborating on APIs.
The challenge is that API development is becoming increasingly competitive, while AI coding tools are changing how developers build software. Postman therefore has to ensure its platform remains central to modern development workflows rather than becoming just another testing utility.
Investor Perspective
Asthana is well qualified to build Postman because he experienced the API problem firsthand as a developer. The company’s early traction came from solving a practical engineering problem rather than trying to manufacture demand around a new category.
Postman’s large user base is its strongest evidence of product-market fit. The platform’s expansion into enterprise teams and API lifecycle management also creates opportunities for deeper monetisation.
The next opportunity is AI. As software agents increasingly interact with APIs, the infrastructure around API discovery, testing, security and governance becomes more important.
The risk is that AI could also reduce the need for some traditional developer workflows. Postman’s move toward Postman.ai suggests the company recognises this shift and is trying to position itself within the next generation of software development.
