Would you buy it? Is it compelling enough to make someone pay money for? Compelling enough for them to try compared to what they normally buy?
Is what you offer worthy of your customers to take a risk? Speaking of, how big of a risk are they taking? If you spend the time calculating the Lifetime Value of a customer, you might realize that you could lose money up front based on how much you get over the next few months/years.
Again... how good is your deal? Anything you can do to improve it? Lower the risks to entry? What’s stopping them from committing?
