20/20 hindsight, etc. A lot of people thought Zuck was crazy to turn down the acquisition offer from Yahoo in 2006, even when the offer got lowered from $1b to "only" $850m. Now Facebook's market cap is more than twice as big as Yahoo's. Alas, these sorts of things are virtually impossible to predict.
"these sorts of things are virtually impossible to predict"
Respectfully - no. (And by that I mean respect++ - I learned a lot from your book!)
The company had been around awhile, and there was data to guide the decision. Growth rates, customer acquisition costs, engineering costs, etc. At the time of the offer, a lot about Groupon's financial model was well known. It could have led to a better decision.
