Finding monetizable pain that you can solve is exciting! But simply building a solution isn’t enough. Remember the business model is the product. With your problem and solution assumptions in check, your next priority should be validating your pricing assumptions. In other words, go make a customer.

The old way was Build-Demo-Sell. The new way is Demo-Sell-Build. Making sales, or more specifically repeatable sales is how you test your product before building it. There is no such thing as a quick launch. There are always details and always delays.

So take your problem/solution findings and first build a demo. The art of the demo is showing the smallest thing possible to convince a customer you can solve their problem. Then turn that into a mafia offer and go make some customers.
