Not asking for a complete strategy but a general idea of where to start at.
2. Go sell it to someone and have them pay you to build it.
3. This will look mostly like a service at first, very custom.
4. Now go and sell part of the thing you just built, or the whole thing to someone else.
5. Build this second one using as much of the first thing as possible. Add whatever features the second company/person wants so long as you can sell it back to person/company #1 or a third company.
6. By this point you should have talked to a bunch of people... you should know generally what people actually want. Take the stuff you built, generalize it, refine it, test it, and then sell it to people in person.
7. for the last step you don't need my advice or anyone else's... you have a product and people are paying you for it. You now know what to do.
This sounds good, but unfortunately this approach doesn't work for may kinds of products - especially if you idea is not niche B2B service.
