Who Are We? Postman is the world’s leading API platform, used by more than 45 million+ developers and 500,000 organizations, including 98% of the Fortune 500. Postman is helping developers and professionals across the globe build the API-first world by simplifying each step of the API lifecycle and streamlining collaboration—enabling users to create better APIs, faster. The company is headquartered in San Francisco and has offices in Boston, New York, Austin, Tokyo, London, and Bangalore - where Postman was founded. Postman is privately held, with funding from Battery Ventures, BOND, Coatue, CRV, Insight Partners, and Nexus Venture Partners. Learn more at postman.com or connect with Postman on X via @getpostman. P.S: We highly recommend reading The "API-First World" graphic novel to understand the bigger picture and our vision at Postman. The Opportunity Postman is now at one of the most consequential inflection points in its history. Enterprises are rapidly shifting from human-driven API workflows to multi-agent systems — where AI agents autonomously discover, call, and collaborate with APIs, tools, CLIs, and each other.

Where Postman today is the API platform for human-first integration , we are building Postman into the agent interface fabric for AI-first integration . That transformation starts with Fabric Gateway — a brand new product, being built from scratch, that will serve as the policy-driven control plane governing how agents connect to APIs, services, and other agents at scale. This is a rare 0-to-1 opportunity inside a company with 40+ million developers already in the ecosystem. About the Team The Fabric Gateway team is building the API gateway for the AI era — one of Postman's most ambitious greenfield infrastructure products. We're a small, high-ownership team wo
