By December of that year, Adobe Systems released a mobile application of the product for iOS. In 2016 Adobe Sign was introduced as a way to request, receive, and submit e-signatures. The product offers integrations with Dropbox, Salesforce, Workday, Box and Microsoft OneDrive.
In October 2020, Adobe signed a deal with online notarization provider Notarize to integrate the company's remote online notarization capability into Adobe Sign.
