DocuSign, a cloud-based eSigntaure platform provider, announced today that its total Series D funding has hit $55.7 million, thanks to recent backing by Google Ventures. Other investors part of this financing round include lead investor Kleiner Perkins Caufield & Byers, along with Accel Partners, Comcast Ventures, SAP Ventures and an unnamed "large global institutional investor."

DocuSign reportedly plans to use the funds to accelerate the growth of its DocuSign Global Network by way of increased customer-focused R&D, deeper vertical industry solutions and faster international expansion.

"The investment by Google Ventures highlights DocuSign's value as a tech disruptor across the Web and mobile platforms, from consumers to global enterprises," Keith Krach, DocuSign chairman and CEO, said in a recent statement. "DocuSign has become the global standard for eSignature by building a viral network of more than 20 million users that attracts 60,000 new users every day."

DocuSign's platform is used by consumers and businesses of all sizes every day, eliminating the inherent issues — cost and lack of security, for example — of physical information capturing. DocuSign can help companies save money as well as streamline business processes.

"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, partner, Google Ventures. "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 millions of consumers."

DocuSign recently announced an extended commitment with zipLogix to help real estate professionals close transactions faster by way of DocuSign's eSignature solution. More specifically, zipLogix's zipForm software now includes a "Send with DocuSign" option, which allows real estate agents to send documents for signature quickly and securely.

Also as part of the agreement, ZipLogix has named DocuSign as its preferred eSignature solution.
