About us

A simple signature.Proof that lasts.

We build DOCUJET so that signing a document is as quick as sending a message, and so that the signature remains provable, by anyone and over time.

Our mission

Take the effort out of signing, not the safeguards.

DOCUJET is developed by Grem S.r.l., an Italian company based in Salerno. Write to us

For years, signing a contract meant printing it, signing by hand, scanning it and sending it back. Or pasting the image of a signature onto a PDF and hoping nobody would ever challenge it. In the first case you lose days, and sometimes the client. In the second you lose the proof.

DOCUJET exists so that you no longer have to choose between fast and secure. The sender uploads the PDF, marks where to sign and sends it. The recipient opens it on their phone, without creating an account or installing anything, and signs in a few minutes.

Everything that makes that signature solid happens behind the scenes, automatically: the record of every step, the seal, the time stamp, the public proof. The person signing never notices. The person who one day has to verify it will.

Behind every signature

What makes a DOCUJET signature solid.

A secure signature

The signer confirms with a one-time code received on their own mobile phone or email. On the plans that include it, the advanced electronic signature (AES) adds verification of the ID document and of the face.

In line with the European eIDAS Regulation

The qualified seal

To the signed document we add a qualified electronic seal and a qualified time stamp, using the services of Namirial, a qualified trust service provider. It does not replace the signature of the person signing: it accompanies and protects it.

Intact document with a certain date

The signature certificate

At the end of every signed PDF is its certificate: who signed, with which contact detail, on what day and at what time, and the SHA-256 fingerprint of the original document. The full record of every step, IP address included, is in the audit dossier you download from the document.

Who signed, when and from where

The public proof

The document's fingerprint is anchored on the Bitcoin blockchain: a public and independent proof of integrity, which adds to the time stamp and remains verifiable even without us.

Verifiable by anyone

Trust is not declared. It is demonstrated.

We are not asking you to trust us. Every signed document can be verified independently: on our verification page, with the European Commission's DSS validator, or directly on the blockchain. Even if one day DOCUJET no longer existed.

How we work

Four principles, no exceptions.

Simple for the signer

Someone receiving a document has nothing to learn: they open it, read it, sign. The complexity is our problem, not theirs.

Precise on the legal side

We say exactly which signature we offer and what it is worth. The right words matter more than slogans.

Proof, not promises

Every safeguard we offer can be checked with tools that are independent of us.

Built for Italy

Interface, contracts and support in Italian. Fixed price, not per user.
