Never forget Guy Kawasaki's method (paraphrased here) for how to value a startup. For every engineer, add $1 million. For every MBA, subtract $250k. What's -$250k in startup valuation worth in terms of shares? My offer to cofound your venture is still a far better deal because I pledge I will not lend my name nor contribute any work. That makes my contribution to your startup $250k greater than the other guy, so I should get $250k more worth of equity. Just my nickel's worth of free advice.
