Jay V is the founder and CEO of Opencode, an open-source alternative to Claude Code that works with any model you want. It's one of the fastest-growing products in AI: 13 million monthly active users, 20X growth this year, and more tokens processed daily than all of OpenRouter. But the overnight success took 16 years, one legal entity, and nine YC applications. In this episode of the Lightcone, Jay explains how Anthropic's attempt to block Opencode accidentally fueled its rise, how 16 years of near-misses prepared him to catch lightning in a bottle, and why most of the world still hasn't experienced the magic of a coding agent. https://opencode.ai Apply to Y Combinator: https://www.ycombinator.com/apply Work at a startup: https://www.ycombinator.com/jobs Transcript: https://ycrootaccess.substack.com/p/how-opencode-became-the-worlds-most Chapters: 00:00 — Intro 00:44 — OpenCode's Explosive Growth 01:16 — 20x Growth, 13M Users, and 7 Trillion Tokens 03:39 — The Anthropic Controversy That Changed Everything 05:43 — Bringing AI Coding Agents to the World 06:39 — When Open Source Models Became Good Enough 08:56 — What Millions of Developers Are Actually Using 13:31 — Why OpenCode Is Huge Outside the US 15:27 — Why Fortune 500 Companies Choose OpenCode 16:36 — The Economics of AI Tokens 20:02 — How Enterprises Are Using Coding Agents 22:58 — AI's New Unit Economics 24:56 — Why Model Choice Matters 29:55 — The Product Decisions Behind OpenCode 34:21 — A 16-Year Overnight Success 41:16 — Why Jay Never Gave Up
