Hello, I’m Charlie Chan.

This site is my personal lab. I document what I’m building, the experiments that work (or don’t), and create tools to help others do the same — especially if you’re building without a technical cofounder.

Why follow along?

More than ever, we can test ideas and build businesses on our own — without waiting for funding or a full tech team. I’m building tools and learning in public as I go.

My background’s in Chemical Engineering, but my obsession is in building tiny experiments and compounding insight over time.

This site will grow as I grow. Thanks for following along.
