Box is a cloud storage company that provides services like file sharing and collaboration tools to enterprises. Founded in 2005, it has since raised $414 million in funding and is now valued at $2 billion. Box has over 82% of Fortune 500 companies as customers and recently redesigned its iPhone app and offered 50GB of free storage. Its focus on security and access controls for enterprises has helped it grow significantly over the years since its initial $350k investment from Mark Cuban in 2005. Analysts predict Box will launch its IPO soon to compete further with Dropbox and other cloud storage providers in both the consumer and enterprise markets.
