Email is not a sharing strategy
Sending an attachment to a partner gives them a copy that you can never revoke. They can forward it, lose it, get phished out of it, or simply forget they have it. None of those failure modes are theoretical. They happen all the time, just usually without consequences. Until one day they do.
The two-axis fix
Good partner sharing solves for two things at once: granular access (the partner sees only what you intended) and revocability (you can shut access off the moment the relationship ends).
- Granular access: share a portfolio, an evaluation, or a document set, not the whole platform.
- Token-protected links: partners get a unique URL that requires no login and works only with that token.
- Live, not static: the packet reflects current data, so a year-old shared link reflects the year-old version of the deal.
- Revocable in one click: when the deal closes or the relationship changes, the link is dead.
What this looks like in practice
For lender packets, partner-share links let you curate a working set (DD docs, underwriting model, demographics) and send a single URL. The lender sees what they need; the rest of your pipeline stays private. When the lender drops out, you kill the link. No drama.
