About
I’m Arturo Díaz. I run Entropy, a marketing science company. We help brands run paid media on evidence: marketing mix models and incrementality tests that show what actually works, so every budget decision rests on a number you can check.
On the side I build small software for myself and the people I work with: a dictation app, a Markdown viewer, a photo culler and a native Google Chat client. They’re on the projects page, and this is where I write about them.
I’m a pilot, and fly whenever I can. Most of all, I’m a husband and the dad of three wonderful kids.
