DocuSign has closed out its whopping series D financing round at $55.7 million, including new participation from Google Ventures. We reported on the first portion of the funding, at $47.5 million, last month. The maker of electronic signature technology, with operations split between Seattle and San Francisco, has been growing rapidly. It is now attracting about 60,000 new users each day, and employs about 270 people.

“We are really poised for growth,” DocuSign CEO Keith Krach told GeekWire last month. “We’ve got a great business model that is a hybrid of SAAS and Internet, and we really believe that in the second half of this decade the vast majority of signatures will be electronic. We are in the midst of building a great company.”

“Electronic signatures are being rapidly adopted by enterprises, small businesses and consumers worldwide due to their convenience, security and ease of use,” said Karim Faris of Google Ventures in a statement. “DocuSign’s market momentum, deep technology and strong team attracted us to them and we are excited to be working with the company as they scale their business worldwide extending their reach to hundreds of millions of consumers.”

Other investors in the round included Kleiner Perkins Caufield & Byers, Accel Partners, Comcast Ventures, SAP Ventures and others. Total funding now stands at about $123 million, including participation from Ignition Partners and Frazier Technology Ventures.
