Postman

The Breakthrough Moment

The founding of Postman as a formal company in 2014 was unusual because the product already existed and had hundreds of thousands of users before the company was officially created—a reverse chronology where product-market fit preceded company formation, demonstrating the power of solving real developer pain points before worrying about business models or organizational structures. The story begins in 2012 when Abhinav Asthana, working as a software engineer at a startup called TeliportMe in Bangalore, India, grew increasingly frustrated with the tedious process of testing APIs during software development. APIs (Application Programming Interfaces) are the fundamental building blocks of modern software—they allow different software systems to communicate with each other, enabling everything from mobile apps calling backend servers to microservices architectures to third-party integrations with services like payment processors, mapping services, or social networks. During software development, engineers need to constantly test APIs to ensure they work correctly, return expected data, handle errors properly, and perform well under load. In 2012, the standard tools for API testing were primitive and developer-hostile. Most developers used cURL, a command-line tool that required typing complex commands with numerous parameters, making it slow, error-prone, and difficult to collaborate on with teammates. Some developers used browser plugins or wrote custom scripts, but no tool existed that made API testing simple, visual, and shareable. Asthana, like countless developers globally, spent hours each week manually testing APIs using cURL, copying and pasting commands, tweaking parameters, and inspecting JSON responses in plain text—a workflow that felt unnecessarily painful for such a common development task. Rather than continuing to tolerate this friction, Asthana decided to build a simple tool that would make his own work easier. He spent a few weeks learning Chrome extension development and built "Postman"—a basic Chrome extension with a simple interface where developers could enter a URL, select HTTP method (GET, POST, PUT, DELETE), add headers and body parameters, click a button to send the request, and view formatted responses. The name "Postman" was a playful reference to sending and receiving messages, like a postal service delivering mail. Asthana built Postman primarily for himself, but he published it to the Chrome Web Store in late 2012 thinking it might help a few other developers facing the same frustrations. What happened next surprised everyone. Within days of publishing to the Chrome Web Store, other developers began discovering Postman through searches for "API testing" and "REST client," and the extension's user count grew from dozens to hundreds to thousands with zero marketing or promotional effort. Developers desperately wanted better API testing tools, and Postman's simple, free solution spread virally through developer communities, blog posts, Stack Overflow answers, and word-of-mouth recommendations. User feedback poured in—feature requests, bug reports, thank-you messages, and suggestions—and Asthana found himself spending evenings and weekends maintaining and enhancing Postman while working his day job at TeliportMe. The feedback revealed that developers wanted more than just basic HTTP request sending; they wanted to save collections of requests, share them with teammates, switch between different environments (development, staging, production), organize requests into folders, and collaborate on API testing. By mid-2013, Postman had surpassed 100,000 users and was growing by thousands of users daily, all organic growth without any marketing spend. The Chrome extension architecture, however, had fundamental limitations that prevented Asthana from building the features users were requesting. Chrome extensions had limited data storage, couldn't easily sync data across devices, were constrained by Chrome's security policies, and depended on Google's Chrome Web Store platform which could change policies or reject updates without warning. Asthana realized that to build a truly powerful API development platform, he needed to create native desktop applications for Windows, Mac, and Linux that wouldn't be limited by browser constraints. This required a decision: keep Postman as a nights-and-weekends side project with inherent limitations, or commit full-time to building native applications and attempting to turn Postman into a real company and sustainable business. In early 2014, Asthana made the leap. He left his job at TeliportMe, recruited two talented engineers he knew—Ankit Sobti and Abhijit Kane—to join as co-founders, and the three began working full-time on Postman from a small apartment in Bangalore. The decision was risky; Asthana had no certainty that Postman could become a profitable business, no experience running a company, and modest savings to support himself while building the product. The co-founders initially bootstrapped Postman without outside funding, living frugally in Bangalore where costs were low and supporting themselves through savings. They spent 2014 rebuilding Postman as native desktop applications using Electron (a framework for building cross-platform desktop apps with web technologies), adding the collaboration and sharing features users had requested, and beginning to think about how to monetize the product beyond the free offering. The native applications launched in 2015 to enthusiastic reception from existing Postman users who appreciated the enhanced capabilities despite needing to download and install software rather than just adding a browser extension. The growth trajectory steepened—Postman reached 1 million users in 2015, 5 million by 2017, and has continued growing to over 30 million users by 2024. The founding team's approach to monetization was patient and developer-friendly. Rather than immediately adding paywalls or restricting features, they kept the core product free indefinitely and only introduced paid team plans in 2016 once they had built collaboration features compelling enough that organizations would willingly pay for them. This freemium approach—generous free tier that serves individual developers, paid plans for teams needing collaboration and governance—became the standard business model for modern developer tools, though Postman was among the pioneers in proving it could work at scale. The company raised its first institutional venture capital in 2016, a $7 million Series A from Nexus Venture Partners, after two years of bootstrapping—notable restraint in an ecosystem where many startups raise funding immediately. The Series A allowed Postman to hire aggressively, invest in enterprise features, and expand internationally. Subsequent funding rounds reflected Postman's explosive growth: $50 million Series B in 2019 from CRV, $150 million Series C in 2020 from Insight Partners, and $225 million Series D in 2021 from Insight Partners at a $5.6 billion valuation. The founding story of Postman illustrates several powerful lessons about building developer tools companies: solving real pain points that developers experience daily creates organic viral adoption that no marketing budget can replicate; patience in monetization and prioritizing product excellence over revenue extraction builds long-term loyalty and sustainable businesses; starting in low-cost geographies like Bangalore allows bootstrapping longer and building more capital-efficiently than expensive Silicon Valley startups; and maintaining founder control and vision through multiple funding rounds enables companies to stay true to their missions rather than being forced into short-term revenue optimization that alienates core users. Asthana, Sobti, and Kane have remained together as the leadership team over ten years, an unusual longevity that has provided Postman with strategic continuity and cultural stability as it scaled from three founders in an apartment to a global company with hundreds of employees serving 30 million developers worldwide.
