Every loan
is paper.
Run the paper.

MarsLOS is the operating system for independent mortgage brokers — pricing, pipeline, borrower portal, documents, disclosures, reporting, and AI in one place.

Every file priced, documented, disclosure-tracked and chased — from one screen.

Priced like
a rate sheet,
not a guess.

Load each wholesale lender's ladder and adjustments. Mars stacks the LLPAs the way the sheet does — against price, not rate — and hands you best execution in points and dollars. Every line below is the engine's own arithmetic, and the borrower can be shown all of it.

The pipeline is a filing rail.

Scroll. Files advance, stamps land, nothing gets lost in a spreadsheet. This is the board your whole shop works from.

SEEN FROM HER PHONE · SHE ONLY EVER SEES HER OWN FILE

Form M-3 · The borrower's copy

They chase
themselves.

The portal is a checklist a person can actually follow: upload from a phone, sign what needs signing, watch the stamps land. Fewer "any update?" calls, and every document arrives named, filed, and encrypted.

Form M-4 · Internal memo

A desk clerk
who reads
every file.

Ask Emery what a sharp processor would know: who's stuck, what's missing, which locks die this week. She reads your pipeline — never an SSN, never a date of birth — and she is instructed never to state a number that isn't in your files.

FROM EMERY — DESK
TO YOU
RE WHO NEEDS A PUSH, 07:58
Three files need a push. SANTOS — appraisal back, re-issue the LE today. OKAFOR — 12 days quiet, pay stubs still out. REYES — clear to close, no closing date set. Lock on PATEL dies Friday. — E.
Plate 02 · While you were on the phone

The desk
runs itself.

A borrower uploads from the portal, the file puts itself away, Smart Docs asks for the next thing, a condition clears — and Emery only taps your shoulder for the one item that genuinely needs you.

Your masthead.

On the white-label plan the borrower never meets Mars. The portal runs on your domain, every screen and email carries your logo and your colors, and the paper signs itself with your name. Same engine, same vault, same Emery — restamped.

It is rolling out now and set up with us by hand — talk to us about white label and we will walk your brand in. Built for shops that sell their own name.

Bring the
whole book.

Export your pipeline from wherever it lives — any columns, any order — and drop the spreadsheet in. Mars reads it, shows you exactly what will be created before a single file is added, and running it twice never doubles a thing.

SEALED
AES-256
AT REST

7.1 Encrypted at rest

Every document is AES-256-GCM on disk. Without the key, the files are noise — including to anyone who walks off with the drive.

7.2 Backed up, encrypted, and rehearsed

Nightly backups, encrypted where they sit, and we restore from them on purpose — so we know they work before the day we need them. Off-site copies are being connected now; until they are, the backups live on the same machine as the data, and we would rather say so than let you assume otherwise.

7.3 The AI is on a leash

Emery is never shown a social security number or date of birth from the loan file, and uploaded loan documents are never sent to her (scanned intake sheets you choose to have read are the exception). Nothing you hold trains anyone's model.

7.4 One shop cannot see another

Every request is checked against the company you're signed into — on the server, on every route, tested by machine.

7.5 Borrowers see only theirs

A borrower can open their file and download what they sent you. Nothing else, and nobody else's.

7.6 Leave whenever

Export every loan (MISMO 3.4), every document, and every contact at any time — including while you're cancelling. No request, no waiting.

Form M-8 · Questions, answered plainly

The fine print,
in large print.

Are there really no seat fees?
Really. One flat rate covers your whole team — add people without the number moving. We think charging per chair penalizes growing shops, so we don't.
Where do the rates come from?
From your own lenders' rate sheets. You load each ladder and its adjustments; Mars prices against them, stacks LLPAs against price the way the sheet does, and shows points and dollars. A live vendor feed isn't connected yet — today the sheets are yours to keep current, and Mars never invents a number it wasn't given.
Can I pull credit and run AUS in Mars?
Not yet. The settings and data model are built, but the vendor integrations aren't — so today you pull credit and run DU/LPA where you do now, and record the outcome on the file. When those land, you'll bring your own vendor account at your own negotiated rate.
How hard is it to switch?
Export your pipeline as a spreadsheet, drop it in, and read the preview — every file it will create, every row it can't, by line number. Nothing is written until you say so, and re-running an import never doubles your book.
Is my borrowers' data safe?
Documents are AES-256 at rest, every request is tenant-checked on the server, borrowers see only their own uploads, and you can export everything at any time. The security section above is written in plain language on purpose — and the encryption, isolation, borrower-access, AI-privacy and export claims are each covered by automated tests.
Can I run it under my own brand?

That is the white-label plan: your logo, your colors, and your domain on everything the borrower touches, with Mars running underneath and never introducing itself. It is rolling out now and set up with us by hand — write to info@marslos.com and we will walk your brand in.

Can I try it without committing?
14 days free, no card. There is also a live demo with sample data — click around, break nothing, buy nothing.
