Box has been highly visible over the past few years. The company, which offers cloud-based content management and file sharing services, attended the Credit Suisse Annual Technology Conference in late November, a sign that management is at least kicking the tires on an IPO. Merely attending an investment banking conference doesn't guarantee anything (Box was also at a Goldman Sachs conference in 2011), but companies don't show up by accident. Box nearly doubled its workforce in the past year to 650 employees, and it was valued at roughly $1.2 billion following a substantial funding round in July that brought in $125 million. Estimates suggest Box may seek an IPO valuation between $2-3 billion.
