SpreadsheetHey, I'm Dan
I'm the founder of Experimentation Labs. You know how NFL players can recall a single play in crazy detail? That's how testing feels to me. I've spent years in the trenches—running experiments, building growth systems, and figuring out what actually moves the needle.
I started this because expertise can obscure what's obvious to others. My goal is to share practical, irreverent insights and build tools that help you ship better products through data. No jargon, no fluff—just what works.
