The Opportunity

Problem

Proptech SaaS companies can't easily scale to enterprise real estate teams because clients require custom APIs for legacy system integrations that exhaust developer resources.

Solution

Browse, customize, and deploy pre-built API connectors from a marketplace built for proptech-legacy integrations. Founders buy or sell connectors for systems like AppFolio or Rent Manager, deploy instantly without coding. Scale sales without custom dev per client.

Target Audience

Founders and CTOs of proptech SaaS companies targeting enterprise real estate teams

Differentiator

Curated marketplace with revenue share for contributors, focused exclusively on real estate legacy APIs.
