I say go and sell the heck out of it. Even though you already built it before doing validation, it of course will be a waste if you don't even try to do anything now. Look at the bright side, you already have something to show. instead of asking "I am working on xyz that will do abc for you", you can now say "I have xyz that can do abc for you"
