gstack Hi, I'm Garry Tan. I'm President & CEO of Y Combinator, where I've worked with thousands of startups including Coinbase, Instacart, and Rippling when the founders were just one or two people in a garage — companies now worth tens of billions of dollars. Before YC, I designed the Palantir logo and was one of the first eng manager/PM/designers there. I cofounded Posterous, a blog platform we sold to Twitter. I built Bookface, YC's internal social network, back in 2013. I've been building products as a designer, PM, and eng manager for a long time. And right now I am in the middle of something that feels like a new era entirely. In the last 60 days I have written over 600,000 lines of production code — 35% tests — and I am doing 10,000 to 20,000 usable lines of code per day as a part-time part of my day while doing all my duties as CEO of YC. That is not a typo. My last (developer stats from the last 7 days) across 3 projects: 140,751 lines added, 362 commits, 115k net LOC. The models are getting dramatically better every week. We are at the dawn of something real — one person shipping at a scale that used to require a team of twenty.
