So I'm coming up with this business plan and I'm crunching these numbers, then I realize something. My business will heavily rely on advertisers. If I can manage to receive an extra $5000 a month from advertisers, my business would officially be a profit business. My question is how many people a month would have to buy from my business in order to even get that much? I'll simplify it, let's say I plan to launch Netflix, how many members do I need before I even begin to search for advertisers?
