vemix.ioDue diligence: view it, never take it.
Share documents with bidders, investors and their advisors under control. Every page carries a personalised watermark, the original never leaves the server, bidder groups cannot see each other — and you see who viewed what, when and for how long.
Due diligence with watermarks, separated bidder groups and an access log.
View, not download
External users see documents exclusively as server-rendered page images. Neither download nor print hands out the original — not a single original byte reaches a bidder's browser.
A watermark on every page
Mandatory and impossible to switch off: the viewer's email address, the data room name and a timestamp are placed dynamically on every page delivered. Every visible page can be attributed to a person.
Bidder groups, strictly separated
Several parties in the same data room that cannot see each other and know nothing about each other. Responses reveal neither group names nor the existence of other documents.
Permissions per folder and phase
Visibility per group and folder with downward inheritance and per-document overrides. Plus staged release: prepare documents in phases and promote groups without touching a single rule.
Q&A inside the data room
Bidders ask questions per group, referencing a folder or document. Your team answers with assignment, priority, internal notes and a full history — and can share an anonymised FAQ with all groups.
A complete access log
Sign-ins, opened documents, pages viewed with dwell time and search queries — as a list and CSV export. Bidder engagement is a core result of the data room, not a by-product.
From an empty room to a closed process.
A data room is populated in draft, equipped with groups and permissions and only then opened — invitations go out on opening, never before. Every step is traceable, and several processes run side by side without getting in each other's way.
- 01
Create the data room — from a template
Pick a bilingual folder template with index numbers ("Company sale", "Funding round" or "Empty") and adapt the tree freely afterwards: rename, move, renumber. Name, description and target company stay internal; externally the process carries a code name.
- 02
Load the documents
Upload PDF, Word, Excel, PowerPoint, PNG and JPEG files in bulk or drop them into the file explorer — the "Data rooms/" branch of the WebDAV drive mirrors every room. Each document is rendered server-side into page images and its text is captured per page for search. Replace a file and it is rendered again.
- 03
Set groups, permissions and phases
For each bidder group you define which folders are visible; subfolders inherit, individual documents can deviate. The permission matrix shows the server's resolved view, not just the rules. Documents are released in phases — promote a group to phase 2 and it sees the new material immediately. And you check every view up front: "Preview as group" shows exactly what that group will see.
- 04
Open and invite
When you open the room, every member receives their invitation by email. External users need neither an account nor a licence: email address, six-digit one-time code, done. Sign-in never reveals to outsiders who is involved in a process. Revocation or a change of group takes effect on running sessions immediately.
- 05
Answer questions
Bidders ask questions in the portal, referencing a folder or document. Your team assigns them, sets priority and due date, discusses in internal notes and replies — optionally with an answer document that you release afterwards. An answer that concerns everyone is shared anonymously as an FAQ. Notifications bundle late arrivals into a single digest email.
- 06
Evaluate the log and close
Every sign-in, every opened document, every page viewed with dwell time and every search is in the access log — filterable per group, exportable as CSV. Closing the room ends access, freezes open questions and keeps everything readable internally; archiving removes the room from the active list.
What the data room can do.
Content & templates
- Folder templates in DE/EN with index numbers: company sale, funding round, empty
- Freely editable folder tree, renumbering at the click of a button (1, 1.1, 1.1.1 …)
- PDF, Word, Excel, PowerPoint, PNG and JPEG — up to 200 MB and 1,000 pages per document
- Bulk upload in the app or maintenance in the WebDAV drive under "Data rooms/"
- Removed documents go to the recycle bin and can be restored
Viewer & protection
- Server-side rendering to page images — no PDF in the bidder's browser
- Dynamic watermark per viewer, data room and time, cannot be switched off
- No download, no print; context menu and shortcuts blocked as a convenience
- Pages load as you scroll, zoom level at double resolution
- "New since your last visit" flags additions since the previous sign-in
Groups, permissions & phases
- Visibility per group × folder with downward inheritance, per-document override
- Permission matrix shows the resolved view: inherited visible, inherited hidden, explicit
- Staged release: prepare documents, promote groups step by step
- "Preview as group" with the very same view the portal shows
- Groups know nothing of each other — not even through search hits or counters
External access
- No platform account, no seat: email address plus a six-digit one-time code
- Invitations go out only when the room is opened
- Sign-in without an existence oracle: no response reveals who is a bidder
- Revocation and group changes take effect immediately; sessions expire after 12 hours
- Portal with your logo, accent colour and footer — after sign-in
Questions & answers
- Questions per group with a group-private number and a folder or document reference
- Assignment, priority, due date, internal notes and a complete history
- Answer documents as data room documents, released to the group afterwards
- Anonymised FAQ release per question — deliberately an individual decision
- Emails on question, follow-up and answer, late arrivals as one digest; CSV export
Search & log
- Full-text search internally and in the portal with snippets and page-exact hits
- Hits jump straight to the page in the viewer
- Portal search only sees the content visible to that group
- Access log: sign-in, document opened, pages with dwell time, search queries
- CSV export of the log; permission and member changes also in the audit log
The transaction lives in vemix.
The NDA before the invitation runs through digital signatures, mandate and advisory agreements sit in contract management, bidders and investors are in the CRM — the data room is the last step of a chain that rests on one data foundation.
