I think a smart businessperson could blow it up much bigger. Open it up to a variety of different industries. Wedding planners, photographers, florists, interior designers, architects, etc. Think big.
Wedding planners, photographers, florists, interior designers and architects have no idea who 37signals is. Consequently they won't be fazed in the slightest by a simplistic job board with relatively poor usability entering their respective markets.
Furthermore, even if they knew who 37signals was - that brand is removed from the product after the sale.
Alternatively, if you seriously believe the success of your job board is due to technical excellence and would map to other markets. Why would someone buy the tech for half a million dollars instead of replicating it within a few months for under 100k dollars?
Using the very same tech staff that he will need anyway to operate it?
To be clear my cursory analysis does not rule on the goodness of this deal for a buyer who believes they can affect the growth variable, it was merely feeling for the edges of plausibility.
Assuming the buyer cannot significantly mitigate any loss of customers resulting from the sale, I looked at the interaction between that crash and expected return. I assumed lower growth rates in my analysis based on the low growth and deviance in the historic cash flow data.
If a buyer got hit with a 1/3 initial crash but believed they could growth cash flows thereafter by at least 10% per year for 5-7 years they could expect an internal return of 21% to 30%, independent of the capital gain on the larger, growing company at the end of the road. The game naturally changes if one ignites such non-linear growth.
