After the solution is built, the expert decided she's "too busy" to return emails.
It happens all the time. Experts have ideas because their 9-5 job requires them to have ideas. They have to push hard for ideas so they will be taken seriously at meetings at work. That's why they are "experts". It's natural for an expert to "push" for her own ideas--otherwise she can't get buy-in from the rest of the organization for their ideas/initiatives and won't thrive.
The quality of the idea is not ass important as the act of pushing for it. Because if an idea does not get support, it's useless, regardless of if it was good or bad.
The moment you ask them to be use your product, they cease to be an "expert" and is now a "user", or even a "paid customer". Suddenly, they don't find the problem so "major" anymore. So you have to really qualify them before diving into the problem. Really make sure they are committed as a user before you start building anything.
I don't really understand this attitude. Why are you keeping this a secret? Aren't you trying to sell your app/service? That seems hard if you're not willing to tell people what it is/does.
Let's do an exercise: I don't know anything about tradeshow. Can you explain to me what you mean by content and how it's distributed currently?
this has occurred to me of course but i just don't think it's true. without giving too much away it's a simple app that makes distribution of content at tradeshows much easier, personalized, and trackable (lead gen/capture for the content producer). if that's not a thing that tradeshows dearly need then i don't know what is.
> How did you come up with the idea? How do you know it's something people want in the first place?
everyone on the "advisory board" has decades of experience in the industry. it was one particular advisor's idea and i've run with it.
