Open markets need open listings.

When listings split across private networks, agents enter them twice and sellers choose without the whole picture.

Open to all
Any brokerage can join, at any size, free.
Transparency as a benefit
Sellers see where their home appears, and why.
The seller decides
Public or members only, with a clear picture of each.
No one company in control
Not a brokerage, portal, vendor or trade group.
The vision

Rivals for every client.One platform for every listing.

Brokerages that compete for every seller and buyer can still share the plumbing: one neutral platform where a listing is entered once, stays its broker's, and reaches everyone on the same terms.

The more brokerages on one platform, the less any one of them can close it.

  1. 01
    Compete where it counts
    Agents, service, marketing and price stay each brokerage's own. The platform carries the listing, nothing more.
  2. 02
    No one holds the keys
    No brokerage owns the platform or gets a private door, and it runs no search site of its own.
  3. 03
    Stronger with each member
    Every brokerage that joins adds its listings for all, and every listing earns its broker the same share.

See it work before you join.

Built for the agent who lists it, the seller who approves it and the MLS that receives it.

List a home form: seller's choice of public now, coming soon or members only, the seller and the date the listing agreement was signed

One form, or the system you already use. The seller's choice comes first.

Works with the system you use.

Five ways in. Agents list once, wherever they already work.

    Your system can send each listing on.

ListOnce
One record, entered once
In the industry's standard fields.
  • MLS rules checked first
  • The seller's choice recorded
  • Listed within one business day of the agreement

For the MLS: a prefilled draft to enter by hand today; direct connections with MLS partners, market by market, starting with a pilot.

Count the hours you get back.

Put in your own numbers. Each listing and each correction is entered once, not once per place.

Members only, when the seller asks.

Never publicly marketed
Members only shows the home to agents at member brokerages, not on public sites.
Every copy traceable
Each member brokerage gets its own marked copy, so a leaked copy names the brokerage it was issued to.
Rules checked first
Entry window and MLS rules are checked before anything goes out.

Each listing earns the same share, whatever the brokerage's size.

Neutral by design.

Competing brokerages share one platform only if no one can tilt it. So the rules are written down.

Every change on record

Each change links to the one before, so history cannot be quietly rewritten.

You own your listings
The listing brokerage owns the listing. Admins can export every listing and its history, anytime.
Governed by members
Designed for a member board, one vote per member, with the code held in escrow.
The industry's open standard
Records use RESO standard fields, so they fit the systems you already run.
Security in plain words
Keys are stored only as hashes. Every request is checked against who owns the record.

Questions brokers ask.

Is it really free?
Yes. Members never pay to join or to list. Data partners will pay for the feed.
Does it replace the MLS?
No. The MLS keeps setting local rules. ListOnce delivers clean records into it and checks those rules first.
We have our own system. Do agents enter twice?
No. Your system can send listings on, or you can connect through your franchisor, back office vendor or MLS.
Who owns the listing?
The listing brokerage owns the listing. Admins can export every listing and its history, anytime.
Can a seller keep it off public sites?
Yes. Members only shows it to agents at member brokerages and never markets it publicly. Each member's copy is marked, so a leak traces back to the brokerage it went to.
Who gets the data revenue?
Participating brokerages, the same amount per listing whatever their size. Running costs come out first.
Is it a home search site?
No. It is the pipe sites draw from, so it never competes with them or with members' own sites.
Who runs it?
Molluso proposes to build and run it, with the code held in escrow and a member board governing it, one vote per member.

Keep your system. Join free.
