Hi Brian đź‘‹

I learned to code.

I’m Gregory Maro. I run a real estate brokerage in New York. At the end of August I started building with Claude Code. Now my agents, my ISAs and our clients all run on software I made.

No dev team, no CS degree, just a lot of late nights. Here’s the tour: first the app, then one lead from the first call all the way to the co‑op board.

The tour

01 BIZZNESS app

Meet my agents’ new best friend.

Paperwork in two taps, who’s on duty, their deals and time off. Swipe over and it’s the team chat, every listing, and a file on every building. Hit the big + and start a deal, an invoice or a listing agreement.

02 ISA dashboard

A lead calls.

My ISA qualifies them, then three clicks: buyer or seller, the borough, the price tier. The agents who cover that tier get pinged in waves until someone says yes.

Yeses line up in the order they came in, each with handoffs this month, answer rate and FUB health. Picking takes two taps, so nobody gets chosen by accident. Then the tracker fills itself in.
03 BIZZNESS app

An agent’s phone buzzes.

One tap from the lock screen: “I’m available.” Seconds later the ISA hands the client over by phone. Afterward, the agent rates the lead, so we know which leads are worth it.

04 LPMAMA notes

The notes beat the agent to the call.

The ISA types shorthand. One click cleans it up without touching a number, name or date. The agent reads it live on their phone.

05 Deal sheet

Offer accepted.

The agent fills in our side once, on their phone. The other agent gets a one-page PDF with every line fillable.

06 REBNY statement

The buyer shows their finances.

Plain questions in, a finished REBNY Financial Statement out, with the debt-to-income ratio worked out, as a Google Sheet and a PDF. And here’s what lands in the agent’s inbox.

07 Client portal

Then the co‑op board.

The board package without the email chase. The buyer gets a personal checklist, uploads from their phone, and sees what’s approved. Every file is checked first.

Also running quietly

So, Brian. Am I in?

Seven weeks ago I couldn’t have told you what a pull request was. Now I merge them before breakfast. I’d love to show you the rest.
