What’s an idea worth?
My answer to What’s an idea worth? on Quora
I like Derek Siver’s model proposed here: http://sivers.org/multiply
To make a business, you need to multiply an idea by its execution. A really great idea is worth $20.
No execution is worth $1. So if your idea is truly great it’s worth 20 x 1 = $20.
If you can pull off just a good execution ($100,000) then congratulations, you have a combination worth $2,000,000.
