See this page for an overview of the new Dropbox for Teams service
Dropbox's position is both enviable and daunting. The company has seen its user base rocket from 25 million to 45 million since April, and it recently secured $257 million in funding from several venture capital funds, on a $4 billion valuation.
At the same time, Dropbox is likely to face increasing competition from some even more popular, and well-funded, companies. Having declined Steve Jobs's offer to acquire the company in late 2009, CEO Drew Houston admits to experiencing a sinking feeling when Apple announced its iCloud service, which remotely backs up images, music, documents, and other data and syncs that content between different Apple devices. That service closely resembles Dropbox's.
