From Side Project to API Powerhouse: How Postman Went Global

Before Postman became a category-defining platform used by millions of developers, it was a personal side project.

In this episode, co-founder and CEO Abhinav Asthana shares how he went from hacking on API tools in Bangalore to leading a global company with nearly 900 employees across three continents.

We talk about:

  • Building a developer-first product that spread through word of mouth
  • Choosing a CEO when everyone on the founding team is an engineer
  • How to reach U.S. customers before you have a U.S. presence
  • Why authenticity beats thought leadership when you're building in public
  • Going from “ramen profitability” to Series A in just 17 months

Whether you're an engineer who’s thinking about starting something of your own, a founder operating outside of Silicon Valley, or just curious how Postman actually works, this episode is packed with tactical insights.
