From someone who has interacted with a lot of investors trying to raise money and pitch a business I started with some friends, I can assure you that a lot of what people think makes a business is bullshit.
We spent months and months building a business plan, doing market research, talking about our IP, our proprietary processes, etc. When talking to all the investors we met while in the Notre Dame McCloskey Business Competition, we were basically informed the business plan wasn't worth the paper it was printed on, we had no IP, and the reason investors won't sign an NDA on your idea is that an idea isn't worth shit. When I actually started building something, when we got the land needed for the other part of our business, and when we had substance (not just words); that's when they listened, offered us money, and things started to work out.
