More than 50 million people in 188 countries have signed and sent documents electronically using DocuSign's cloud-based e-signature technology. The 12-year-old San Francisco-based company lets users in multiple industries and professions electronically "sign on the dotted line." The process reduces transaction time, the need and cost of paper and increases security by encrypting all documents and creating an audit trail.

The company has 100,000 customers worldwide and claims that 50,000 new users sign on every day. Prices range from $10 per month for individual users to $125 per user, per month for business accounts, with an unlimited amount of electronic signatures and priority customer service.

In April the company announced that the largest sub-franchisor of real estate giant RE/MAX had chosen DocuSign's technology to allow its agents to complete transactions. The company has raised more than $230 million in venture capital since its founding, from investors such as Sigma West and Ignition Partners, and is using that money to rapidly expand its business outside the U.S. It's well on its way: DocuSign is available in 43 languages.
