The Story

APIs Don't Have
to Suck.

Abhinav Asthana built Postman on a Friday night because he was annoyed. Not visionary-annoyed - just plain annoyed. Debugging APIs at a Yahoo internship in 2009 with tools that barely worked, he made a note. Three years later, that note became a Chrome extension. Another two years later, it became a company. Now, 35 million developers can't ship software without it.

That's not an accident of timing. It's what happens when someone who has been a programmer since fifth grade builds something for programmers. No sales pitch. No roadshow. Just a product dropped on the Chrome Web Store that spread - first through Yahoo teams, then through entire engineering departments at Meta, PayPal, Microsoft, Salesforce, and into remote offices on every continent, including Antarctica.

"Nobody was addressing the needs of the developer when it came to testing and documenting APIs."

Abhinav Asthana, Postman Co-Founder & CEO

Postman today is the operating system for API development. But the company's origin is simpler than the pitch: one developer, one problem, one weekend. Asthana uploaded the first version to the Chrome Web Store in 2012 and watched it hit 500,000 users before he had a company name.

He grew up in Basti, a small city in eastern Uttar Pradesh, moving across small towns wherever his civil engineer father was posted. When his father bought their first Pentium I PC, the rule was non-negotiable: no gaming. So Asthana taught himself HTML, CSS, Flash, and PHP. By eighth grade, he was building complete web applications. By Class 9, he had his first client - a $80 cheque from someone in New Zealand - and a freelance operation running out of a small-town UP bedroom, servicing clients in the UK and US.

Career Arc

Before Postman,
Three Other Bets

Asthana did not build Postman in a vacuum. He had already launched three companies by the time he turned Postman into a formal business. Each one sharpened his instinct for what developers actually need, versus what they say they need.

BITS360 came first - a 360-degree virtual campus tour tool he built at BITS Pilani's Goa campus before finishing his degree. It became wildly popular among BITS aspirants across India. His timing was accidental and remarkable: he launched five months before Google rolled out Street View globally.

Grayscale Design followed - a design consultancy that kept the lights on and sharpened his product instincts.

TeliportMe came next - a crowdsourced Street View-style mobile platform that got into 500 Startups and raised over $500K. It was at TeliportMe, building across Android and iOS with dozens of third-party APIs, that Asthana kept running into the same wall: no good tooling to test, debug, or document API calls.

"Every time I completed a project or application, it was very gratifying. It's the best thing in the world - you don't have to seek approvals from anyone."

The Platform

The API Layer
of the Modern Web

Postman did not grow through a sales team. It grew because developers told other developers. Within a year of going on the Chrome Web Store, half a million people were using it. Asthana describes the growth as viral - not engineered virality, but the organic kind: tools that save real time get shared at standups.

When he formalized the company in 2014 alongside co-founders Ankit Sobti (now CTO) and Abhijit Kane, the strategy was simple and hard to argue with: keep making the product better, and let developers do the talking. "Our product has sold itself," Asthana has said - a line that sounds like a boast until you look at the growth curve.

The Bangalore-to-San Francisco move in 2017 was about proximity to the developer community, not a rejection of its Indian roots. The engineering core stayed in Bangalore. The new HQ was about being in the room where the conversations about the future of software were already happening.

"Focusing on the developer experience - we really got good at that."

What's Next

Building for
Machines, Not Just Humans

In January 2025, Postman launched something that reframed the entire platform: an AI Agent Builder that lets developers design, test, and deploy AI agents using the same API infrastructure they already use to build software. The bet is direct - if AI agents communicate through APIs, then Postman is already the tool that understands APIs better than anything else on the market.

The launch included full support for the Model Context Protocol (MCP) - Anthropic's open standard for how AI models talk to tools and data sources. Postman now generates MCP servers from its network of over 100,000 public APIs, including verified integrations with Salesforce, UPS, and X. The vision is that the infrastructure for human developers becomes the infrastructure for AI agents, with Postman as the connective tissue.

"Unlike an AI copilot, Agent Mode natively executes tasks understanding the intent of an API developer, with the goal of reducing the time required to build and deploy APIs from weeks to a few hours."

Abhinav Asthana, 2025

On the lighter side, Asthana has been watching the "vibe coding" phenomenon with a wry eye. In a 2025 post that hit a nerve with developers: "Developers in the pre-vibe coding era: Lines of Code is a BS metric to measure my productivity. Developers in the vibe coding era: I am generating thousands of lines of code every hour!"

2025

The Agentic Era

Postman launches AI Agent Builder + MCP support. 100,000+ APIs now accessible to AI agents through the Postman network.

The Person

What Investors
Won't Tell You

The version of Asthana you get from pitch decks and funding announcements is a founder who scaled a $5.6B company from a Chrome extension side project. That part is accurate. The part that gets less airtime is how he did it.

He did not build Postman to flip it. He built it because he was genuinely annoyed by bad tools, and that annoyance never quite went away. The investors who walked with him in Palo Alto before leading the Series C describe someone who prefers a conversation on foot to a boardroom pitch. Insight Partners called him "humble, hands on, grounded" - which in venture-speak is the highest possible endorsement.

His father, a civil engineer, imposed a hard rule on the family PC: no games. It was not meant as a lesson in entrepreneurship. But the result was a kid who learned to code because it was the only acceptable use of the computer - and who discovered that building things was more satisfying than playing them.

"Staying brutally honest with your product, code, design and achievements helps you improve continuously."

Abhinav Asthana

Character Traits

Codes his own tools - still thinks like a developer, not just a CEO
Bootstrapped instincts - built Postman for free before taking any money
Product-led growth believer before it was a category
Brutally honest self-assessor - "no approvals needed" is a genuine operating philosophy
Community first - builds for developers by listening to developers
Long-term compounder - more focused on direction than milestones

Key Anecdotes

At Class 9, he received an $80 cheque from a New Zealand client for a website he built. His first paid programming work, done from a small town in UP.
BITS360 went live five months before Google Street View. There was no overlap, no rivalry - just a college kid in Goa who had the same idea a few months earlier.
Postman reached half a million Chrome users before Asthana had a company. He had not even told his co-founders yet.

Fun Facts

Things Worth Knowing

Oct 1, 2014

Postman's official birthday - also the day three developers decided the Chrome extension needed a formal home.

The No-Gaming Rule

His father banned games on the family PC. The accidental policy that turned a small-town kid into a programmer.

Name Origin

Postman references the HTTP POST method. A developer in-joke that became one of tech's most recognized brand names.

Antarctic Users

Postman has active users on every single continent, including Antarctica. The most remote API debug session on Earth.

The $80 Cheque

First professional income at age 13 - a client in New Zealand paid him $80 for a website. Built from Basti, UP.

Chrome Extension Ghost

Postman started as a Chrome browser extension - a format that Google later deprecated. The product outlived the platform it was built on.
