Is Your Targeting Market Right Size?

If you're an andy hacker in their targeting market, how can they know whether or not their market is the right size? For a market that has no competition, try to figure out how many people have this problem. And if the competition is a gigantic corporation, then the market may be too big for you. If your competition is a couple of scrappy bootshop s, you might actually bea in an interesting niche. That would be my suggestion here. We've also targeted way to big market that had venture fondat competition. Like a the local food n start up that i was talking about at the time that we were trying to go for that. Didn't know that before
