DocuSign adds 21st-century meaning to the phrase "Sign on the dotted line." The 11-year-old company offers cloud-based e-signature technology that lets users across a whole host of industries and professions sign and send documents securely online.

As the global standard in e-signatures, the San Francisco-based company's service reduces transaction times, increases security and reduces cost by eliminating the need for paper. Its 105,000-plus business customers comprise 48 million users in 188 countries, and DocuSign claims about 40,000 new users sign on every day.

Software company Adobe acquired DocuSign's main competitor, EchoSign, in 2011. Since its launch, DocuSign has raised more than $200 million in venture capital—including an $85 million round in March—reinforcing speculation that it is preparing for an IPO before the end of the year.
