Similar to talking VC, there is no guarantee. But unless you have a truley secret sauce going on, ideas by themselves rarely matter. People have a tendency to overestimate ideas. They are remarkable easy to come up with. I have been in brainstorming session, where we would come up with at least 10-12 really good ideas within an hour. Usually it is execution that matters at the end, as you don't know what it works or what it doesn't. Tested ideas that move the needle a lot on the other hand are valuable: Eg. We tried to get sign ups doing X, but we failed, but then when we did Y and Z and added these two features we saw a huge increase in signups and retention. -- That's direct learnings from the field, and it is both expensive and somewhat valuable.
