ZorroSign is an end-to-end Digital Transaction Management (DTM) platform which goes a step further than electronic signature. After one of our co-founders introduced an innovative new technology – electronic signature, he then went on to solve the larger problem when it comes to DTM and digital transformation of businesses. That is our unique and proprietary Document 4n6 (Forensics) Token technology that helps authenticate, verify, and protect both digital and printed versions of electronically signed documents. That is not only legally binding but it also holds up in court.

With ZorroSign API, developers can take advantage of our entire platform and technology to enhance their business processes and help digitally transform their business completely and securely.
