DocuSign claims it has over 475,000 customers and hundreds of millions of users in more than 180 countries. Signatures processed by DocuSign are compliant with the US ESIGN Act and the European Union's eIDAS regulation, including EU Advanced and EU Qualified Signatures.

In April 2018, DocuSign filed for an initial public offering. At the time of the IPO, the largest shareholders were venture investment firms Sigma Partners, Ignition Partners, Frazier Technology Ventures, and former CEO Keith Krach was the largest individual shareholder. None of the original founders, or current CEO Daniel Springer, are major shareholders. The company went public on the NASDAQ on April 27, 2018.

DocuSign was founded in 2003 by Court Lorenzini, Tom Gonser and Eric Ranft. Tom Gonser came up with the idea when he was at NetUpdate, a company he founded in 1998 and served as CEO of. Through its history, NetUpdate had acquired several companies, including an e-signature start-up in Seattle called DocuTouch that had been funded by Timberline Venture Partners, Bill Kallman and Jeff Tung with $4M. Timberline invested another $1 M in the merger into Netupdate. DocuTouch held patents on Web-based digital signatures and collaboration. With internal support from Gonser, Lorenzini negotiated the purchase of certain DocuTouch assets from NetUpdate and started DocuSign. Gonser then left the NetUpdate Board to focus on DocuSign full-time.

DocuSign services are offered either by subscription or free of charge as a mobile device app. Signatures and documents are uploaded, then encrypted and a unique hash created. If a signed document is later checked, the hash will not match the information stored by DocuSign if a document has been tampered with or compromised.[46] More than 20 billion pieces of paper and 608,000 barrels of oil have been saved by the company through avoidance of wasted printouts for signatures.

DocuSign Professional emails recipients an electronically signed document requesting review of a document after it is uploaded. Each party must agree to complete business electronically, review the document, and apply a signature. Signatures may be added from a stored copy of a signature or generated automatically by the software. Phone confirmation and background checks are offered as premium services.

DocuSign released its mobile app DocuSign Ink in November 2011. It is available free of charge, and runs on Apple iOS, Google Android and Windows Phone operating systems. DocuSign Ink allows users to sign and annotate documents by attaching a stored signature, which may be created in graphic design software, captured from an image of a paper document or selected from a variety of prefabricated signatures based on the user's legal name. The saved signature can be applied to PDFs, word processing documents and images. To complete a document, participants apply their signatures and send completed documents to cloud storage for review.
