Spotify, DNSimple, AWS, SendGrid I would really like to pay for Github, but the private repo limitations are holding me back. I'd much rather pay $10-20/mo for unlimited private repos if it meant each collaborator also had to be on the same $10-20/mo plan. For now, my private projects are hosted for free at Bitbucket.
