This is very real. A friend of mine started a company with over a million in seed funding with what basically amounts to just an idea. Years later, the company isn't doing that well in terms of sales/revenue, but they still manage to raise money because they have a couple obvious acquisition targets. It seems crazy to me to throw millions of dollars at a company with the hopes that one of maybe three or four megacorps in the industry will acquire them, but investors buy into that, and that's all that matters.
