DocuSign, the best-known software-as-a-service (SaaS) brand for electronic signature, just received 47.5M in additional investor funding. According to execs, this will help accelerate growth internationally and include a UK-based data center as well as further internationalization on the signing capability. When signing documents in China, it is more than just a nice feature to have native signing and sending instructions.

The injection will also help build out more industry solutions and take on more of the complete transaction — something that will be required for long-term success for the e-signature market. As part of the investment, Kleiner Perkins' Mary Meeker will join the DocuSign board. Formerly of Morgan Stanley, Mary is well versed in mobile, Internet, and cloud-based markets, and may help cultivate partnerships with emerging lighter file-sharing and cloud-based content solutions — a natural trajectory for e-signature platforms to jump on their steep adoption curves. On the heels of Adobe's acquisition of EchoSign, this shows acceleration of the e-signature market and is consistent with adoption Forrester is seeing driven by mobile and customer engagement trends.
