Hi, I’m Charles. I help build PostHog.

I joined as the first non-product hire when we were 10 people and had no revenue. Since then, I’ve helped scale PostHog to $70m ARR, 220 people and $194m raised - building and leading teams across ops, finance, people, sales, support, and marketing.

Today I’m working on company-wide growth, new product launches, and the occasional weird idea. I also like writing about building ambitious software companies.

I’m always happy to compare notes with founders and operators - just put hello in front of this URL!
