For brokers & firms

Your closed deals are comps. Put them to work.

Upload the comp book you already keep. It stays private, and your deals show up in every report you run. Bring the office and everyone works off one shelf.

On a report you share: $218/SF · 19,400 SF · Mar 26. No address, no total price, no notes — and your client's range still matches yours to the dollar.
Exit one · publish

Publish a comp to CompNinja's records and it carries a green Verified badge with your firm's name on every report that uses it.

Exit two · your firm

Send a comp to the firm's shelf, one at a time, with your name on it. Automatic sharing is off unless someone turns it on.

And that is the whole list

Both take a deliberate click, and you can take either back. Nothing else leaves the vault.

ProAddress Explorer needs a paid seat. Drop a pin, set a radius, and see every sale, listing and vault comp we hold around it, yours badged. A free account still runs a full report on one address at a time.
Three · your firm

Your colleague values a building at 2pm. The firm has it by 2:01.

A firm account gives the office one shelf. Reports people share land on it with their name attached, searchable by address, market and property type, and still there for whoever joins next year. Nobody has to remember to forward anything.

Yours

Your own work stays yours

Colleagues see what somebody shares, and nothing else. Your reports, portfolio and watchlist never land on the shelf on their own.

Never retroactive

Sharing only applies going forward

Turn on automatic sharing and it covers new reports only, never work already run. Your own setting beats the firm's either way.

The vault stays a vault

A private book is shared one comp at a time

You share a vault comp one at a time. It never enters CompNinja's public records, and it doesn't travel whole in a report sent outside the firm.

Broker shop

Your shelf holds comp sets, BOVs, market reports and lease abstracts.

Development shop

Your shelf holds land comps, rent comps, absorption studies and feasibility packets.

Tell us which one you are at signup and the shelf uses your words for it.

Individual Pro
$100 / month

Unlimited reports, ten years back, the vault, Address Explorer, exports and your branding on them.

Firm · every seat gets Pro
$79 / seat, min. two

Everything in Pro, plus the shelf and the deal board. Whoever owns the account holds billing and can add or drop seats any time.

Try it before you upload a single row.

A free account values any commercial address, three years back.
