Moving further toward a paperless world, Seattle's DocuSign said today it raised $10 million from Sigma Partners to complete its second round of funding.

DocuSign provides an electronic signature service that works through a Web browser. It received initial funding from angel investors, followed by $4.6 million from Ignition Partners and Frazier Technology Ventures in 2004.

Founded in 2003, the company now has about 35 employees and 1,000 customers, most of them small businesses.

In case you were wondering whether the documents for Sigma's investment were signed electronically, they were, says DocuSign's Jerry Johnson.
