"Flowr is pitched squarely at small-to-medium businesses, and the pricing reflects that. It’s free for a basic account, which allows up to five users. Premium accounts, with a range of additional features, cost $59 per month for up to 15 users (additional users are $3 per month)."
Flowr's online business collaboration tools updated
The growth over the next decade in Enterprise collaboration is going to be around SMEs that today are using email as their only tool. Microsoft is going after this area with Office 365 but when you look at an app product like Flowr you see that a company can get moving with most of the same features from the Cloud for a fraction of the investment.
The app economy has blown the rough off development making faster innovation at lower cost and opening the pie to more smaller players. Will Microsoft be able to respond in time, well that will be very interesting.
