I think it's worth pointing out that in order to "sell" to investors (as opposed to customers), having the product (and the customers!) ready actually is very important. So the proper sequence is: 1. Sell. 2. Build. 3. Pitch to investors. 4. Repeat with more resources. Inexperienced non-technical founders sometimes get the steps 1-3 backwards.
reconciling creativity with the market is a really longstanding problem in lots of areas. so I'm really interested in discussion that leads to any insight. I'm curious about 1 before 2. Any attempt I've made in the past to understand market interest without having something that people can actually touch has always been really squishy. People aren't that interested to talk, when you do they always say something like…
I think that is why point 1 is "Sell," not "Interview" or "Imaginary sell." For example, some people put up a web page, run some ads, and have a complete signup process that once the CC is entered they get a "thanks for your interest- we'll be in touch when we get it built and by the way we didn't really charge your CC."
We've had discussions before on this board about whether or not that's ethical, IIRC.
