Current revenue is not the right to focus on for an early stage acquisition. They collectively raised $13M through the Series B in May 2010 and were acquired for $212M cash in December 2010 (technically ~$250M for the whole deal). A ~16–19x return, especially that early, is pretty excellent. That speaks to the product itself and its future growth potential and place in the market more than current revenue.
