FOR MORTGAGE PROFESSIONALS · BETA

She watches your clients' rates. So you don't have to.

Rosie the Rate Guardian is the AI I built for my own book — she patrols every client's rate 24/7, stays quiet, and only speaks up when there's a real problem or a real opportunity. Not a list. A name, a reason, and the moment.

I promised my clients I'd watch their rate every day — and for a while, I was the algorithm.Past a hundred clients, no human can rightfully keep that promise. So I built Rosie, named after my family's guardian dog: the one who runs the whole fence line first, sits quietly in the middle, listens while everyone sleeps — and only nudges you awake when something's actually out there.

Rosie doesn't replace the loan officer's mouth. She aims it.

🌙

Patrols while you sleep

Every client, every day — the whole book, not the handful you happened to think of.

🤫

Stays quiet

No dashboards to babysit, no daily reports. Silence means all is well.

📞

Nudges you at the moment

A name, a reason, and the right second to call — where your skills actually win.

In testing now. Opening to a handful.

Rosie runs on my own clients today while we finish validating and testing. When she's ready, we're considering opening her to a small group of MLOs and small-to-mid-size shops. Not a launch — a handful. The right ones.

Drop your cell and check the box — the workbook arrives as our first text.

Beta interest list only — no pricing, no commitment, no spam. We'll only use this to reach out about the Rosie MLO beta.

Prefer your thumbs? Text ROSIE to the number from the show — same short list.
