The product
Three things, done properly.
Most data rooms are 200 features deep and 2 features good. We picked three and put the work in.
02 / NDA gate
A stamp, not a contract app.
Toggle on. Visitors type name and email, accept your mutual NDA. Audit log captures IP, timestamp and acceptance. CSV or signed PDF export.
03 / Analytics
Page-level, human-only.
Heartbeat pings every 5s, tab-visibility aware. Email scanners and bots filed separately so you don't celebrate a robot opening your deck four times.
