Introducing Trello Business Class
I developed a similar product over the last few years (http://www.thetaboard.com) and have been waiting to see how the FogCreek guys were going to monetize Trello. I had resigned to leaving my product as free in the face of such a free, strong market leader. Now that Trello has established a price/feature point, I'm tempted to to crank out some features and see if I can't monetize it.Trello have been pretty transparent that they would eventually offer some sort of premium package in the future but they kept adding so many free features that it was getting harder to imagine what kind of features they could actually charge for. The features they are charging here are nice but they aren't real game changers and I thought they had already offered some of them (data export, Google integration).All that being said, I think Trello is a great product and I'm sure they'll pay for more than a few nights at the pub with this new revenue stream!
