Contribution margin expands with scale.
Gross margin improvement is driven by infrastructure leverage and a lower support burden per active workspace.

Dynamic watermarking
Every view carries accountability.
Every page carries the verified recipient’s identity and view time, so a screenshot points back to a person instead of disappearing into an anonymous leak.
Rendered at view time
One source file. A distinct trace for every reader.
RoundOS uses the identity already verified before the room opens. The name, email and view time appear on the page automatically; no recipient-specific PDF needs to be prepared.

Generated automatically.
The same document resolves into a named view for every verified reader.
Not an IP-address guess.
The watermark uses the email identity already established by the room.
Trace the screenshot.
It does not pretend to make screenshots impossible; it makes casual sharing accountable.
The view and mark agree.
The watermark points to the same recipient event recorded in room activity.
Deterrent, not a lock
Let honest recipients work normally.
A seller can share the same model with several bidders without hand-stamping a separate PDF for each. If a page surfaces elsewhere, its mark identifies which verified view produced it.
Connected controls
Watermarking and download policy are different decisions.
A document can be watermarked and downloadable, or watermarked with downloads disabled. RoundOS keeps the trace, the policy and the resulting activity in one room record.
RoundOS vs manual stamps
Automatic accountability for every recipient view.
Create and track a separate copy for every person.

Questions
Watermarking, answered.
01Does the watermark stop screenshots?
No. It makes a screenshot traceable to the verified recipient and viewing time, which deters sharing without claiming an impossible technical lock.
02What information appears?
The recipient identity and the date and time of the view are rendered on the document page.
03Can I use it only on sensitive documents?
Yes. Apply watermarking where the material calls for it rather than forcing one blanket policy across the room.
04Can a watermarked file still be downloadable?
Yes. Watermarking and download policy are independent controls.
05Is the view also in the audit history?
Yes. The identity used for the mark is tied to the same room activity record.
