The Bottlenecks

Why Deals Stall?

In real estate, speed is currency. Yet, most brokerages are slowed down by clunky IDX feeds, manual data entry, and slow mobile sites. We solve the four technical hurdles that kill conversion: Data Fragmentation, Latency, UX Friction, and Lead Leakage.

Fragmented MLS Data

Brokers struggle to normalize data from multiple MLS feeds (RETS/RESO). Inconsistent fields break search filters and ruin the user experience.

Slow Search Speed

Standard WordPress plugins choke on large datasets. If a property search takes more than 2 seconds, high-intent users bounce.

Legacy Mobile UX

Modern buyers expect a smooth mobile experience. Legacy agency sites often lack the interactive maps and instant booking features that mobile users demand.

Manual Lead Entry

Without automated routing, leads from contact forms sit cold. Integrating CRM workflows is essential for efficient agent follow-ups.

PropTech Architecture

Custom Real Estate Platforms

We don't just build websites; we architect Marketplaces. From high-frequency trading platforms for REITs to hyper-local search portals for luxury brokerages, our solutions are engineered for inventory velocity and agent productivity.

01

Custom IDX & MLS Portals

Build a search experience that stands out. We build custom IDX pipelines using the RESO Web API. By indexing listings into Elasticsearch, we deliver sub-second search results even across millions of properties. We implement Mapbox for "Draw on Map" search and school district overlays to keep users engaged.

Predictive Deal Scoring

Real estate moves faster than human analysis. We act as your integration partners, connecting your proprietary MLS data with enterprise-grade AI models. By engineering secure pipelines to OpenAI, Twilio AI, and Valuation APIs, we automate the manual grunt work—lead qualification, listing copywriting, and data normalization—so your agents focus purely on closing.

We don't build models; we engineer them into your workflow.

Most brokerages struggle to actually use AI. We bridge that gap. We write the middleware that securely passes your property data to Large Language Models (LLMs) and returns structured, actionable insights. From auto-drafting descriptions to scoring investor deals based on historical yields, we make AI practical for your business.

Valuation API Integration

We connect third-party AVM services (like HouseCanary) to your platform to display estimated property values alongside your listings.

Description Generators

We integrate OpenAI APIs to help agents draft property descriptions quickly based on the features selected for the listing.

Virtual Staging Connections

We can build workflows that send property photos to external virtual staging APIs, returning furnished images for your gallery.

Chatbot Integration

We configure programmable chat interfaces that can answer basic questions and collect lead details before notifying an agent.

Engineering Standards

Built for Scale

Real estate data is heavy. We optimize for sub-second velocity anddata sovereignty. Unlike rented SaaS platforms, we build infrastructure where YOU own the leads, the listings, and the algorithms.

High-Performance Search

We optimize query structures and asset delivery. Using Elasticsearch and caching strategies, we ensure property results load instantly to keep users engaged.

Client IP Ownership

We build custom solutions where you own the code and the database. Unlike SaaS platforms, you have full control over your leads and listing data.

Inclusive Design

We implement best practices for accessibility. This includes proper ARIA labels, color contrast, and keyboard navigation to ensure the site is usable by everyone.

Data Security

We follow industry standards for security. We ensure data is encrypted in transit and at rest, and we implement secure authentication flows for user accounts.

Integration Ecosystem

Seamless Connectivity

We speak the language of modern real estate. From legacy RETS feeds to modern RESO Web APIs, we connect your platform to the world.

Technical FAQ

Engineering Questions

Migrating from IDX Broker or BoomTown is a major decision. From Mapbox clustering to handling millions of property records without crashing the browser, we answer the technical questions that matter to your CTO.

It depends on the project. For high-performance custom portals, we typically recommend a 'Headless' architecture using Next.js to ensure maximum speed and design flexibility, but we can also work with WordPress if required.
