About

From first launch to what compounds.

I started building products in 2017, mostly to solve problems I had myself. One of those side projects turned into a company, which turned into an acquisition, which turned into the capital and the credibility to do it again — this time on purpose.

These days I split my time between shipping my own products, backing early-stage founders as an angel investor, and writing down what I'm learning so the next round of builders can skip a few of my mistakes.

Building

Shipping product under Compound Labs, my current studio.

Investing

Writing early checks for founders who build in public.

Writing
