Bill Gates, Steve Jobs, Elon Musk - founders at the top who owned it.
More directly, Gabe Newell and Valve.
It might be that google started with Page/Brin and co-ownership might have weakened that a bit, and now they are not to be found.
Not that a single founder is a surefire recipe.
Bill, Steve, Elon, Gabe, were never alone masterminds and definitely not single founders because in companies they created there always was someone else who had shares.
