[Scrive](https://www.scrive.com/) is another advanced competitor with features similar to HelloSign, that include storing documents, notifying involved parties, visible signatures, document templates and forms. It even stores signatures in [Guardtime](https://guardtime.com/) blockchain solution. But again, it's a proprietary vendor's solution, especially when it comes to document storage.
