Start up valuations are a totally disconnected number from anything that you would think of as a normal business valuation. Valuation largely a function of the competition for the shares in your company. The only way to figure this out, unlike jack's magic valuation calculator, is to go talk to professional investors like jason and be like, hey, i got to start up. What do you think is worth? And then talk to enough of them, and you'll end up with proper valuation.
