The Opportunity

Problem

Bootstrapped proptech founders struggle to integrate legacy real estate APIs like MLS into their small-business-focused apps, leading to project delays and technical debt.

Solution

MLSBridge acts as a secure proxy between your app and legacy MLS APIs, managing complex authentication, compliance, and throttling automatically. Founders connect once via a simple dashboard, then query normalized JSON data via our REST API. This eliminates weeks of integration headaches, letting you focus on building features for small real estate businesses.

Target Audience

Differentiator

Tailored specifically for bootstrapped proptech with small-business focusβ€”pre-built schemas for agent tools, not bloated enterprise solutions.
