Google is one of them, I know that. Are what are the others?
Also, mention new and promising startups build by programmers.
Apple
Microsoft
MySQL
Et al? Unless the question should be re-worded, What are some of the big companies built by programmers where the CEO was not a programmer, I'd think 100% of software companies are built by programmers, no ?
Dropbox. At least the Dropbox story suggests they were mostly engineers from the start.

Uber definitely comes to mind.
Side trivia: Travis Kalanick's apartment was known as the jampad before he got too busy with Uber. Anyone can knock on Travis's door for brainstorming, anytime. Drunk engineers working for start-ups, would go to his place in the middle of the night and be like "Dude, my db architecture is not scaling, help me out" and he actually did help them out.
