I started on this on day 1 - it's quite literally from zero. It's an idea I got quite recently, and haven't done any work on it until starting this experiment. I guess every startup has a day 1 where you can't have spoken to any potential customers yet when you start :-)
But you're totally right, I should have spent day 1 speaking to people, instead of/before even starting building any of the prototype. Already trying to set that lesson into action and starting day 2 by talking to people about the idea!
