Achieving a profitable product/market fit

Good post. Points out the real need of other methodologies like Customer Development and Business Model Generation for finding profitable product/market fit.

Leancamp's a good example of this too. It has product/market fit, and passes the Net Promoter / Sean Ellis tests. But the business model itself isn't easily sustainable or scalable, which is where I've had to place my attention the last few months.

David Heinemeier Hansson of 37 Signals made the same point about pricing at SXSW last year. He encouraged people to charge more, and pointed out that 37 Signals' experience is that the quality of customer feedback and customer relationship goes up with the more you charge.
