But its  adjusted operating income is expected to be in the red, at negative $20  million. The hope is for Square to reach profitability in 2012 with  gross revenue of at least $200 million."
 1. Dropbox - A  free service that lets you bring your photos, docs, and videos anywhere  and share them easily. Founded in 2007 and based in San Francisco, CA,  it's estimated value is $4 billion. The CEO is Drew Houston / Investors:  Dropbox is rumored to have closed a massive round at a $4 billion  valuation led by Index Ventures last month. It received seed money from Y  Combinator and, in fall 2008, Sequoia Capital led a $7.2M Series A with  Accel Partners. The analysis? Before the round was reported in August  2011, rumors were flying that Dropbox could be worth as much as $8  billion. Due to tanking markets or an interest in specific investors,  Dropbox settled for a lower valuation. The $4 billion valuation could be  justified. Dropbox makes it easy to store and backup documents in the  cloud, sync them between devices and retrieve them later. It solves a  problem everyone has, so it has a very big potential market. Dropbox's  costs are always going to go down, because cloud computing costs are  always getting cheaper. On the revenue side, Dropbox's revenues are  always going to go up. It's a freemium business model, and freemiums  works best when the value of the services go up over time. Most people  won't pay to back up a few files on Dropbox. They'll pay to store them  all.
