"Founders think of startups as ideas, but investors think of them as markets. If there are x number of customers who'd pay an average of $y per year for what you're making, then the total addressable market, or TAM, of your company is $xy. Investors don't expect you to collect all that money, but it's an upper bound on how big you can get." I would really love some more color on this. What about a product that addres…
Genuinely new markets are really rare. They do happen -- VMWare was a great example. But they are few and far between. This is why lack of competition is often scary to potential investors -- paradoxically -- they ask themselves, how attractive can this supposed new market be if there are no other companies going after it?

This is the approach we're taking at Fogbeam. We've identified a beachhead market we're going to pursue to try and get initial traction, done some simulations based on the number of such customers, potential price points, etc., and come up with some potential revenue numbers and what-not. NOW, the next step is to get out and prove that our numbers actually make sense and hold up in the real world. Of course, they won't really, at least not according to our most optimistic projections. But the hope is that they do hold up well enough to get this thing off the ground...
