Secure document sharing for M&A and corporate finance advisors
The information memo goes out before the data room exists.
Six buyers get the memorandum. One walks. Three weeks later the seller's margins turn up in a competitor's pitch. The early stage of a process is the least controlled part of it, and it is the part that runs on email. GCN.ONE gives each buyer their own encrypted share, revocable on its own, with a record of every download.
The riskiest documents go out before the data room opens
Teasers, the information memorandum, the first model - these travel by email weeks before anyone provisions a data room. They reach people who have signed an NDA and people who have not signed one yet, and once they are attachments they are copies you cannot withdraw.
A data room solves this later in the process, and solves it well. It does not help on the Tuesday you need the memorandum in front of nine buyers, and it is not something you spin up for a teaser. Meanwhile the documents that decide the price are the ones moving with the least control.
How a process works with GCN.ONE
Built for a live process
The delivery record, in plain terms
For any document that was actually downloaded you can issue a delivery certificate: a signed record of what was delivered, to whom, and when. The signature is cryptographic, so anyone can check it at our public Verify page - it does not depend on our word, or on our continued existence as a company.
Our audit log is tamper-evident and publicly anchored, so the history behind a certificate cannot be quietly rewritten. This is strong, independently checkable evidence of delivery. Whether specific statutory or contractual notice requirements are met in a given process is a question for the applicable law and the applicable documents; we make no claim to be a qualified delivery service under eIDAS.
Confidentiality and compliance
Encryption happens in the browser and the keys never reach us, so client confidentiality is protected structurally: there is nothing readable on our side to disclose. What the servers do see is metadata - sender, recipients, timestamps and sizes. All infrastructure runs in the European Union under EU jurisdiction and is built to GDPR standards.
