The process

Where Dillien sits in an M&A process

  1. Sell-side prep

    Build the room before anyone is invited. Uploads index themselves against the list.

  2. Buy-side invited

    Invite the other side when the room is ready. Each bidder group sees what you open to it.

  3. Buy-side diligence

    Several bidder groups work in parallel, each blind to the others.

  4. Findings noted

    The buy-side records deviations against documents, privately.

  5. DD report → signing

    The report generates from the findings. The log is exportable in full.

The request list

A ready-made M&A request list, or your own

A new room opens on a request list written for M&A, so it can be live in minutes with nobody drafting it first. Or bring your own: it imports as an Excel file, with the room built around it — categories, numbering and wording as you wrote them. Upload yourself or send it to us and we set the room up for you.

Features for M&A

The four features that matter most in M&A

  • 01

    Several bidders, one room

    Invite multiple bidder groups into the same room without them seeing each other, and phase access by round — everyone in phase one, the shortlist in phase two. All of them working at the same time, and you control who on the sell-side may upload.

  • 02

    Assignments and work packages

    Hand requests to a reviewer or to a work package the team shares, and see who has what.

  • 03

    Resolving requests

    Upload a file, write an answer, or mark a request not applicable.

  • 04

    Access, watermarks, log

    Restrict per file or per group, watermark on view, control export rights, and export the complete activity log.

AI

Your AI, with the deal’s structure

Ask a connected assistant “which contracts have a change-of-control clause?”. It answers from the documents in this room, with every source named, and it can see which requests are still open.
