Adobe has acquired EchoSign, a provider of electronic signatures. All EchoSign full-time employees, as well as its founders, will join Adobe.

Adobe says EchoSign’s solution will be a key part of its document exchange services platform. It will be integrated with Adobe’s SendNow, FormsCentral, and CreatePDF.

“Adobe’s document solutions help organizations turn inefficient, paper-based workflows into streamlined electronic ones,” said Kevin M. Lynch, vice president and general manager of Acrobat Solutions, Digital Enterprise Solutions at Adobe. “By adding electronic signature capabilities to Adobe’s document exchange services platform, we will be addressing the need to provide better customer experiences by significantly reducing the time, cost and complexity associated with having a document signed.”

On the EchoSign blog, CEO Jason Lemkin wrote:
