Ask HN: How extensive should we make a product demo for investors?
As someone coming from an agile background, my thought was to very roughly prototype the basic feature of the product that would be one of its selling points and show it in action as a "proof of concept" of that being doable. My partners though believe that we should do much less and show just the rough UI of the product without it actually being able to perform any functionality.
I'd like to understand what's usually expected out of teams at this seed stage, because I'm personally concerned about not selling vapor, but perhaps my engineering background is holding me back on this one. Is there some rule of thumb for this? Does it strongly depend on the kind of service/product you're trying to sell? Are there perhaps resources/articles out there that you guys used when you were deciding how far to go with a prototype?
Thanks!
