David Fox
Founder & CTO

David Fox is founder and CTO of LookZook. David got his start in programming and UX as a game developer during the golden age of Flash gaming. Since then he’s applied that knowledge and transitioned to the web: becoming a Blink contributor, writer and speaker for various events like the O'Reilly Fluent conference. In his free time, David enjoys studying psychology, cooking, playing video games, and beating his friends at poker.

"I love tools like WebPagetest, but I always had my gripes when using it. It was a pain to setup any non-rudimentary test; I could never see anything beneath the viewport (like buy buttons on Amazon); and the data was so hard for anyone not in the know to understand, that I ended up regularly creating presentations so my clients understood my findings. So I created LookZook, so I (and you) don't have to do that anymore 😀"
