For firms — Pro version

Your shop’s comp book, working inside every report.

Brokerage and development shops run on deals they closed themselves. Upload that book once and it becomes a private vault — yours on every report, shared only where you say so.

I. Upload
The book you already keep
A CSV out of your own system, a comp sheet as a PDF, or a screenshot. Confirm the column mapping once and 214 deals are in.
II. Store
It becomes your vault
Your closed deals appear in your own reports, badged as yours, beside public records and verified submissions. Nobody else sees them.
III. Share
Ask a colleague directly
Message anyone at the firm from inside a report: request a comp on an address, answer with one from your vault, and the thread stays attached to that property. Sharing is per comp, off by default, and withdrawable.

No address, no total price, no notes leave the vault — and your client’s value range still matches yours to the dollar.
