Companies · The engine

Five companies. One engine.

Each sells a spatial product real estate pays for today — and each writes to the same corpus. Described here by role in the system, not by market.

The five
01
Capture
listing3d.com

Listing3D

3D virtual tours for listings, with native syndication to Zillow. Agents buy marketing; the system gets a scan. Listing3D is the instrument — every tour it delivers is a capture event.

In the system — writes imagery and geometry to the corpus.

02
Infrastructure

EchoCV

The white-label capture stack — hardware, immersive player, and booking system — run under an enterprise's own brand. Where Listing3D captures one listing at a time, EchoCV installs the capture engine inside other companies.

In the system — scales capture beyond our own hands.

03
Marketplace

3DApartment

A residential listing marketplace built on immersive tours — where captured space meets the renter and buyer, and where the demand that funds capture originates.

In the system — creates the demand side of the loop.

04
Intelligence

PropertyPulse

AI property intelligence on New York's public-record spine — ownership, valuation, and opportunity, ranked. The layer that joins every captured interior to a verified market record.

In the system — writes the market record to the corpus.

NexusCall

AI voice agents that answer, qualify, and follow up — converting the demand the rest of the stack creates back into new listings. Every conversion restarts the loop.

In the system — closes the loop. New listings mean new captures.
