The Opportunity

Problem

Solo proptech founders can't gain traction for their property listing apps because real estate agents stick to entrenched platforms like Zillow.

Solution

Agents bulk-import MLS/Zillow data with one click, then customize in your app. Auto-maps fields, preserves photos/details for frictionless migration. Founders attract agents tired of Zillow's fees by offering easy onboarding and ownership.

Target Audience

Solo proptech founders developing property listing apps targeted at real estate agents
