Dropbox plans to tap the money for expansion – through acquisitions and partnerships – as well as for new hires. The San Francisco-based company said it had 45m users who access 1bn files every three days. It provides a certain amount of storage for free before charging people for extra capacity.
It is run on the so-called fremium model, offering two gigabytes of storage for free, while 50 gigabytes costs $9.99 a month and 100 gigabytes costs $19.99 a month.
Dropbox, which has not disclosed its revenue, competes with other services like Google Inc’s free Docs.
So far, Dropbox has raised $257.2m that includes early investors Sequoia Capital, Accel Partners, and Hadi and Ali Partovi.
