Spent the last 12 years of my career distributed across technology startups & investing. For much of this time, I studied network effects in a professional capacity and via independent projects. Spent several years at App Annie, a startup originally built on data network effects. There, I led a global, cross-functional team, working across product, marketing, and sales. Advised leading tech companies like Spotify, Shpock and Trainline. Before that, I was an early-stage investor focused on commerce businesses.

I have been quoted or mentioned in leading publications, including Reuters, Wall Street Journal, Forbes, Business Insider, The Guardian, Sifted, Techcrunch, and AngelList Weekly. My prior independent work has also been referenced in Philip Tetlock's book, Superforecasting.
