First, Kanban tends to be a small-group thing, even within large businesses. I'm sure someone in IBM is going to pay $200/year for a site license, but I doubt IBM is going to make a strong, centralized license control. Heck, it's not worth the TIME for a team to have the three meetings and twenty emails required, not for $200. And really, why should they have a complex pricing model? It's not like Trello is expensive to develop/support/operate. If they can get 10k organizations to buy a $200 license, they make a cool $2M for a not-complex piece of software with a not-complex business model. That's a very high profit margin, and still cheap enough to repel price-based competition (even free).
