How to keep buyers from seeing each other’s questions in a data room?
Keep competing buyers out of each other’s questions by putting each bidder in its own question group, leaving share-all-answers off, and keeping reply-all email out of Q&A.
A published answer should reach only the bidder who asked. Reply-all on a process email is how the wall fails.
Q&A isolation (definition). One question group per bidder.
Threads stay private until the sell-side publishes.
A published answer reaches only that bidder’s group.
Email is not this wall.
How the wall is built
Firmex’s own Q&A optionsinclude a checkbox: “By default, share all answers with all Question groups.” Leave it off. If it is on, every published answer goes to every bidder and carries a Public label. iDeals documents five routing roles - question drafter, question submitter, answer coordinator, expert, and answer approver - and bidder confidentiality unless you turn it off. Staging the files those questions point at is how an M&A advisor should stage data room access from IOI to LOI. What belongs in the index is what should be in a sell-side data room index.
| Control | What it does | How it fails |
|---|---|---|
| One question group per bidder | Threads stay inside that group until the sell-side publishes. | Dumping every bidder into one group. |
| Leave share-all-answers off | Firmex's default-share checkbox. Off means the answer goes to the asking group only. | Leaving the RFP template on. That template shares all answers with all groups. |
| Publish only to the asking group | A published answer reaches that bidder's audience, not the process list. | Publishing, then forwarding the thread, or marking it Public. |
| Keep reply-all email out of Q&A | The wall is the room. | Answering in email and cc'ing the process list. |
What Firmex and iDeals win, and what they do not
Firmex and iDeals win the routing-role job: coordinator, expert, approver. A boutique sell-side that needs that workflow should stay on those products. See Firmex Q&A setup and iDeals Q&A roles. A published-price room can still isolate bidders without those roles: one audience per bidder, a thread private until the M&A advisor publishes, and a published answer that reaches only that audience. Document requests are never published. Cashpian is one example of that shape. It does not have coordinator, expert, or approver routing.
| Job | Who wins | Why |
|---|---|---|
| Coordinator / expert / approver routing | Firmex / iDeals | Those products have the roles. A published-price room generally does not. |
| One group per bidder, share-all off | Any dedicated room that actually isolates groups | The setting, not the logo. Drive comments and reply-all email fail this job. |
| Published answer reaches only that bidder | A room whose publish is group-scoped | Firmex Public answers, a shared Q&A spreadsheet, or an email thread. |

If the files are already in a folder, grade which row they are on. Cashpian is a gated room for that packet. It is not a listing portal. It does not sell the company or run the deal.
