Many investors
A transaction has one counterparty on one timetable. A round has a dozen, arriving over months and moving at their own pace — one at term sheet while another has just signed the NDA. Access is set per investor and opened as each one progresses, so a late arrival walks into a room whose requests are already resolved.
The room counts what each investor has opened, how often, and what they have asked, so you can tell who is moving and who has gone quiet.
The request list
A room opens on a ready-made fundraising request list, so the answer to “what does an investor expect to find” is already in front of you. Work down it, and the room fills itself in the order an investor will read it. Or bring a list from your lead investor: it imports as an Excel file, and if you send it to us we set the room up with you.

Features for a round
01
Work the request list first. Upload what you have and each file lands against the request it answers, so the room an investor opens is tidy and complete rather than a folder you are still sorting.

Five things worth reading this week
02
An investor joins by invitation, with no licence, no account to buy and no training. The ones who pass never think about it again.
03
Start an investor on the deck and the summary numbers; open the contracts and the cap table when they ask for them.
04
Questions land against the document rather than in your inbox, so the round stops being a thread you have to remember.
AI
Ask a connected assistant which customer contracts carry change-of-control or exclusivity terms. It answers from the documents in this room, names every source, and can see which requests are still open.

The contracts with your second- and fifth-largest customers need their consent on a change of control, and the reseller agreement grants Nordic exclusivity until 2027. The master services agreement restricts assignment, not a change of control.

A data room provides structure, oversight, and secure sharing of information. Many professional investors expect the process to be run in a data room — it builds trust and reduces the risk of misunderstandings.
