Interesting concept. Would it be possible to share a demo of what a signed document looks like?

Here's a rough test: https://www.dropbox.com/s/ltglpxexfaxoplk/Test%20Subject.pdf...

A production version obviously wouldn't have the language about it being incomplete or not legally binding.

On the backend, it just uses HelloSign for the signature.

Here's a much better version of what actually gets sent by Lob: https://www.dropbox.com/s/r5oh7qut3f3qic5/ltr_5e9a1648c3d137...

Too many typos and too little information about how confidential mail is printed and posted in a confidential manner.

The page is literally asking you to use it for sensitive documents without even so much as a privacy policy.
