FORTUNE — DocuSign, the electronic signature provider, said has raised $47.5 million in a round of financing led by Kleiner Perkins Caufield & Byers. As part of the deal, which also includes investments from Accel Partners, SAP Ventures (SAP) and Comcast Ventures (CMCSA), Kleiner partner Mary Meeker will join DocuSign’s board of directors.
With the new financing, the 8-year-old company will have raised a total of $117 million.
“Our business is growing at a tremendous clip,” Keith Krach, DocuSign’s chairman and CEO, said in an interview. The company will use the additional funds to accelerate investments in research and development, international expansion and to go after certain vertical markets, Krach said. (Krach will be speaking at Fortune‘s Brainstorm Tech conference in Aspen, Colorado next week.)
The company, whose e-signature service is used by everyone from consumers, to small business owners like realtors, to giant companies like HP (HPQ), currently has 20 million users and is adding about 60,000 new users a day, said Krach, who has been chairman for the past 3 years and took over the CEO post last year. In the past year, the company has nearly doubled in size to 270 employees.
