Joel spells it out in his announcement[1]. In the future we'll continue to add free features to Trello (there is a lot of exciting stuff in the hopper)—anything that is a common feature, useful to anyone, will be free. We’ll also continue to develop new Business Class features that help large organizations manage Trello, and we may come up with other things to sell to people who are getting a lot of value out of Trello. In the meantime, we sure appreciate the cookies! [1] http://www.joelonsoftware.com/items/2013/04/30.html http://www.joelonsoftware.com/items/2013/04/30.html
