Todd Sherman
Hi, I’m Todd. 👋 I’ve spent my career building consumer products that shape how people create, discover, and connect. Currently, I’m a senior director of product management at Instagram, where I lead the Creators org. Previously, I led Instagram’s Relevance org and founded YouTube Shorts, taking it from its first prototype to more than 2 billion monthly users and 200 billion daily views. Earlier, I worked on Stories and publisher tools at Snapchat, and on tweets at Twitter, where I led the effort to make tweets longer.
My work spans zero-to-one product development, growth at massive scale, content ecosystems and network effects, recommendation systems, and applying advances in AI and machine learning to products used by billions of people.
This site is where I share what I’m tinkering with: AI prototypes, hardware experiments, games, tools, data visualizations, and other explorations driven by curiosity.
