Building Substack | Sachin Monga (Substack, Facebook)


Sachin Monga is the Head of Product at Substack, a platform that I personally use every day, and love. Before Substack, Sachin co-founded an app called Cocoon, which he ended up selling to Substack. Before that, he spent over seven years at Facebook as a PM working on video and camera products, building out the developer platform, and leading the ads growth team. In today’s episode, we dive deep on all things Substack. Sachin shares what it’s like transitioning from a large product team at Facebook to a small growth team. He discusses how to work with a hands-on founder and why you must be comfortable with rapid change in a PM role. He also shares unique features of Substack that make it an optimized experience for readers and writers, how he’d like to see it improved, and tips for anyone wanting to get started writing online.
