JetBrains have fantastic tools/products and a very pragmatic business model that is easy to understand. They spot real developer issues and solve the basics, that's why they are successful.
You won't find startup-y inflated delusions and useless-crap features there.

Sublime and Microsoft also are making it work - as are a number of smaller IDEs. Editors and dev tools tend to be pretty profitable as long as you remember the golden rule - let the small fish pirate freely, charge nothing for college students... and go after any of the large corporations using it - those are the people who subsidize the entire tool.
