Even if you answer all their questions get used to hearing No, because everything an investor says is usually no. If they say they're interested in your product, or they want to hear more about it or send me your deck and I'll get back to you in a couple weeks or get back to me when you have more data or get back to me when you start earning revenue or get back to me, etc. It just means no, no, even if they say they're going to invest in your company, even if they say they want to put money into your company that still means no, because what I have learned is that there is only one yes. And that is when they physically write a check out to you. And it cashes in your bank account. That is when you have a yes and I know it sounds silly.
I know that saying that everything is no and there's only one yes but it's so true because it's happened to me many many times
