Charging for your product helps you find out who your customers are…We had all different types of people sign up for free [ScreenSteps Live] accounts including bloggers, educators and small businesses, but the only type of customer that signed up for paid accounts were those who were doing tech support. They were businesses and organizations that were in the middle of tech support nightmares. And ScreenSteps Live made the nightmare go away so they happily paid the monthly subscription fee. We instantly knew who our customers were. This guided both our marketing and development efforts.
