If you look at his resume, it lists mostly management positions. He apparently had two websites that he sold off with some very valuable domain names (jeux.fr: "jeux" is the French word for "games"; football.fr: football as in soccer, France's most popular sport). I've only had one website sold off to venture capitalists on me and they led it to failure. I didn't own it and didn't see any money from its sale, but I did most of the programming behind it (think MyFitnessPal clone with weekly lessons and a chat room for weekly meetings).

Edit: Also, it seems he used Wordpress for a website with only one page.
