SOUND FAMILIAR?

Your real estate platform has outgrown the way it was built.

Listing data falls out of step with what is current in the MLS.
Agents publish the same listing to several places by hand.
Property, owner, and deal data lives in separate tools.
Deal pipelines, calculations, and payments are tracked in spreadsheets.
The platform slows down or breaks as more agents use it.
The developer or agency who built it has moved on.

WHY CHOOSE STACKWORX

Real estate platforms are a core part of our work

We work long-term on Zentap, a real estate marketing platform serving 20,000+ agents, and have built real estate platforms from scratch around MLS, property, and deal data.

MLS and property data

MLS integrations, property and owner data, and automated data processing that keeps listings aligned with current market data.

Built for agents at scale

Platforms that tens of thousands of agents rely on daily need to stay reliable as usage grows. That is the work we do on Zentap.

Long-term ownership

We stay on as the team that maintains, monitors, and extends the platform after launch, instead of handing it off.
