Three months? Can you share any data or case studies around such a number? Part of me finds it unbelievable (and part of me really wants to believe).
From a look at the two books mentioned here, though, neither seem to clear that bar.
Zero to Sold is about FeedbackPanda, which took 2 years. (Still impressive.) And Company of One, from a skim, appears to focus on services businesses — totally reasonable to get to six-figure revenue and therefore seven-figure valuation, but not terribly interesting as product companies and fairly difficult to exit via a sale.
I'd love to see some case studies of the 3-month number. The more I think about it, the more possible it seems (with a fair bit of luck).
