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.

FAQS

Before You Get Started

What does Stackworx do?

We build and take ownership of the systems your business runs on: custom Shopify apps, Ruby on Rails platforms, third-party integrations, and practical AI workflows. Most clients come to us when off-the-shelf apps and quick fixes stop scaling.

Do you only build new products, or can you take over an existing system?

Both. A large part of our work is taking over existing Rails and Shopify codebases, stabilizing them, and then extending them. We start with a technical audit so you know exactly what you have before anything changes.

How do you add AI to a business that already has software?

We add AI inside the systems you already run rather than bolting on a separate tool. Typical work includes content generation, document and data extraction, product recommendations, and support automation, shipped as a focused AI Integration Sprint with measurable outcomes.

How do engagements usually start?

Most clients start with a Technical Audit or an AI Integration Sprint. From there we move to an MVP build or a dedicated product team on a monthly retainer, depending on how much ongoing work you have.

Which industries do you work with?

Mostly ecommerce brands on Shopify and SaaS companies in PropTech, InsurTech, and FinTech. Our platforms have processed 32M+ transactions and serve 20,000+ real estate agents.

Where is your team, and how do you work with US clients?

Our senior engineering team is based in Lahore, Pakistan, and we contract with US clients through Stackworx LLC, our Wyoming company. We work across time zones with regular overlap hours, async updates, and long-term ownership of the systems we build.
