The visual CRM for real estate professionals
Your book of business,
on a map.
Every note you’ve ever taken on a property — displayed, organized, and one click away.

What is BlockBook?
BlockBook is a visual-first tool for organizing your real estate data — a map-based CRM for real estate professionals. Import the property list you already have and see every building, owner number, and call note on a map instead of in a spreadsheet. It's built by a working broker for the way brokers actually work. If you're tired of notes scattered everywhere and follow-ups falling through the cracks, BlockBook is for you.
Why BlockBook
Real estate is a visual business. The tools never were.
You’d never buy a building you haven’t stood in front of. So why prospect from a spreadsheet? BlockBook puts your properties and every note on the map — the visual part of the job no other real estate software gives you.
See it. Remember it. Organize it.
01
See it.
Click any building: street view, parcel outline, APN, and use, right there. Filter the map and turn the result into a list.
02
Remember it.
Log the call in one tap. Dictate a note in the car and it lands on the right building, timestamped.
03
Organize it.
Sort properties into lists, by street, by type, by who’s due for a follow-up, and work them in order. Comps sit on the same map.
Try it
Click the pin. Then log a call.
This is BlockBook’s map of Brand Blvd in Glendale. Open the pulsing building, tap a call outcome, and watch its pin change. The owner and notes here are made up.
Click the pulsing pin on the map.
Its Dossier opens here: street view, county data, the owner, and every call note.
