They have an amazing product and keep adding new features (e.g. recently added git support!). Awsome customer service, a person responded to my feature suggestion within 12h.

Most importantly they have a good business model. Most startup's see a problem that needs solving and solve it with no regards to how to make money from it (ad revenue will not make you a millionarie unless your google!). They will ultimately fail. I like companies which actually have a little bit of business acumen and can actually find ways of making money from their product. 37signals is another company that does this well
