Since it wasn't disclosed, I'm guessing less than the amount raised. Doesn't seem like something PayPal as a business would be interested in, so it's most likely a talent acquisition.
in spite of the added incentive of a reportedly low asking price, Yahoo opted not to make a deal.
So, while PayPal and StackMob declined to share details on the acquisition price, it doesn’t sound like this was a blockbuster deal. Furthermore, while StackMob had a good run, it doesn’t come as a complete surprise that StackMob struggled in its efforts to reach profitability and scale to the degree it had initially hoped.
It sounds like maybe investors will break even and employees get jobs.
