Real estate agents are concerned that private listing data (PLN) will be shared with Zillow and accessible to buyers before agents can control the exposure.

Existing MLS and listing platforms do not allow agents to prevent sharing of private listing notes with consumer-facing sites like Zillow, reducing agent control over listing exposure.

Implied Software Gaps

Agents need a way to block or restrict specific real estate portals from accessing their private listing data.

App Concept

AgentLock Data Vault

A platform that lets agents control exactly which parts of their listings are shared with third-party sites. It creates permission-based data layers so private remarks and early listing data stay within the agent network until the agent chooses to release them.

Key Features

Granular permission settings per listing for third-party syndication
Automatic redaction of private remarks and pre-MLS data
Audit log of who accessed listing data and when
One-click block on specific sites (e.g., Zillow, Zenlist)

Target Users: Real estate agents and brokerages in the United States who list properties on MLS and want to control data sharing with consumer platforms.

Revenue Model: $19/mo per agent subscription; free tier for agents with fewer than 5 active listings
