For the teams running M&A, real estate transactions and fundraising: sell-side preparation through to signing, with everyone who has to be involved.
At a glance
All of it included, in every plan.
Every request, its answer, and its status in one list.
Questions anchored to the document they are about.
Deviations noted privately; the report built from them.
Requests and your own tasks, assigned to a person or a work package.
Several bidder groups at once, blind to each other.
Can you go through the diligence room for Project Meridian?
I can read it once you connect it. Your access decides what I can see.
Connectors
Connected assistants read the room too, scoped to their user's access.
How it works
Starting from the request list means the room knows the shape of the deal from day one. A document is attached to the request it answers, a question to the document, a finding to both. The whole path is connected end to end, which takes the reconciling off whoever sets the room up and keeps it straight.
What follows from this
Is the 2025 audit in the room?
Yes, and it answers request 2.1.

It sees which request a document answers, and what is still open.
The whole path leaves with the deal: requests, answers, questions and the activity behind them.
Coverage comes from the list itself, rather than from someone compiling it.
Use cases
Pick the closest match. Each page shows the room configured for that deal type — the structure it opens on, the parties in it, and the questions it raises.
Sell-side prep through signing, with several bidder groups in one room.
Single-asset and portfolio transactions, technical and commercial diligence side by side.
One room, many investors, each seeing only what you have opened to them.
Each opens on a request list written for the deal you pick — edit it, or import the list your firm already uses.
Product
Where the work starts
Resolve a request by uploading a file, writing a text answer, or marking it not applicable.
Questions in context
Questions attach to the file they are about. Anything that needs an owner becomes a task against the question, assigned to whoever has to answer it.
Buy-side only
Note findings and deviations directly against documents, invisible to the sell-side, then generate the DD report from them.
Who does what
Select requests, set a priority, and hand them to one reviewer or to a work package the team shares — and add tasks of your own for work the request list does not cover.
AI and integrations
A connected assistant reads the room through Dillien, scoped to exactly what you have given it access to.
What has been pledged as security under the loan agreements?

Searching the data room
Read 3 documents
There is one loan agreement in the room. It is secured by a pledge over the shares in both subsidiaries and a first-priority mortgage over the property. It also calls for a pledge over trade receivables, and no such pledge is in the room.
Security
EU data residency. Two-factor authentication by email on every account, encryption in transit and at rest, and a complete audit log of everything that happened in the room.
Getting started
A room is live in minutes on the request list for your deal type. Bringing your own works the same way, and an empty room is there if you want to start from nothing — send us a list and we set it up with you.
Pricing
No charge for more users, more storage, or a deal that runs longer than planned, and no binding period. The cost of a room is known before it starts.

You can now connect a Dillien data room to ChatGPT through the Dillien VDR plugin, and bring both documents and the request list straight into Saga. They are the first assistants on a list that keeps growing, and every one is scoped to the access the user already has.
