They sign before they see anything
Sending an NDA as a separate attachment and hoping it comes back signed is not a process. Attach the agreement to the document itself, and access becomes the enforcement.

Confidential Investment Agreement
Confirm credentials and agree to non-disclosure to unlock document.
The usual sequence is backwards
Most people send the NDA first, wait, chase it, receive a scan, file it somewhere, then send the actual document. Days pass. Half the time the document goes out before the signature arrives because the deal is moving and nobody wants to be the bottleneck.
By the time you notice the NDA was never returned, the deck has been read.
What the gate does
Nothing loads until they agree
The recipient sees your agreement text, types their name and email, and accepts. Only then does the document render. There is no "skip" and no preview.
The signature is tied to the view
Each acceptance is recorded against that specific view — name, email, and timestamp. You know precisely who agreed and when, and which session followed.
Your agreement text
Use your own NDA wording. Set a default across your account and override it per link when a particular deal needs different terms.
Stack it with other gates
Combine with email verification, a one-time code or a password when the document warrants more than one hurdle.
Works on every file type
PDFs, decks, spreadsheets, video — the gate sits in front of the viewer regardless of format.
