Ask HN: What are some remote companies that have had successful exits?

I've been thinking about remote companies lately and believe we're going to see a lot more of them in the future.

Looking around I can find many examples of successful remote companies (Buffer, Treehouse) couldn't find many examples of companies with successful outcomes aside from MadMimi (GoDaddy, $45m) and WooThemes (Automattic, $30m).

Who am I missing?
