Jeff Bezos was a hacker. He didn't call himself one because he also had significant business & financial skills, but he worked as a quant for D.E. Shaw. D.E. Shaw is the Google of hedge funds; anyone there is more than a match for the Ph.Ds at Google. Bezos's degree was in EECS, and his childhood projects would easily have gotten him into YCombinator.

Intuit was cofounded by Tom Proulx, who wrote the first version of Quicken himself. Scott Cook gets most of the credit because of his determination, but without either of them, the company wouldn't exist. It certainly was not an outsourced startup.

Wikipedia I'll grant you. Though the concept of wikis was invented by Ward Cunningham, who certainly was a hacker.

YouTube was started by 3 ex-PayPal employees. Steve Chen and Jawed Karim were certainly hackers, Chad Hurley was more design. They built the initial version themselves.
