Unified APIs built $200B of market cap: Stripe, OpenRouter, Cal.com share one playbook
JosephJacks_ · x · 2026-08-29
A widely shared observation: Cal.com offers one API to schedule any calendar, following a proven pattern—Stripe (one API for any payment rail), Hugging Face (one library to download any model), OpenRouter (one API to use any model), Plaid (one API to get data from any bank), and Twilio (one API for voice/text). Together these unified-interface companies represent roughly $200B of market cap.
The implied lesson: building a unified abstraction layer over fragmented supply is a repeatedly validated, massive business.
