Dropbox are in talks to go IPO shortly and it's sure to be the next high-tech flotation. Dropbox are in the cloud storage/file transfer business and typically used to share video, something which we do a lot of in Streamabout, a couple of times a day.
So if you want to send of receive a large file, Dropbox would be one answer. Mind you, we don't use it but prefer a competitive product 'Wetransfer' which honestly, we find better and quicker than 'Dropbox'. But that has nothing to do with it.
Dropbox's value is in the 4 billion usd range with 200 million users and frankly, was one of the first to get into this space. So it has benefited from 'first mover advantage'. Founded in 2007 - imagine, 6 years later it's worth 4 Billion (!) - it's one of those sites still banned in China and Ireland's own, U2's The Edge and Bono, are investors.
Mind you, both of them did well out of the Facebook float. Imagine...Bono earned more money in one day with Facebook than he has from a lifetime of music!
Based on San Fran, Dropbox seems to be ready and ripe for a floatation, making billionaires out of its 2 founders and then other investors. File transfer and cloud storage is a good business to be in with a good future and Dropbox are at the front of that - like them or not.
It will be a good opportunity when it's announced and probably the next big high tech IPO. Which a lot of companies are opting for these days rather than staying private. It seems to be a "quick fix" get-rich scheme rather than what the business requires and early inventors/investors seem to want to "get in and get out".
Frankly having given the business all the pain a young tech start-up requires, I'm not surprised that once there is an opportunity to cash-in, they take it. An IPO is a good fast way to achieve that.
