Evaluate your startup's product cost

Will your problem be expensive to solve? and will your customers have the money to pay for your solution?

Yes

Great! it's obvious the more you can charge the better. Only as long as your target customer has the pocket to afford your solution!

You may be in trouble if you're charging too little or your target customer simply doesn't have the means to afford even the cheapest incarnation of your solution.

Not sure

Try to find a problem that people are actually willing to pay money to solve and a target customer that actually has the means to afford it.
