Centum Logics
Case Study · Real Estate Lead Gen SaaS

Find movers before they search. The first-call advantage.

Centum Logics designed and built Lead2Move — the multi-tenant SaaS platform that watches Redfin, Estate, and LoopNet 24/7. The moment a listing status changes, addresses are matched against claimed local territories and delivered to a mover's dashboard the same day.

01 — The challenge

Moving companies lose jobs by being second.

Local movers typically buy shared leads from marketing brokers. These brokers sell the same lead to 4-5 competitors at once, forcing a price race-to-the-bottom. Movers needed to bypass these broker pools entirely and find home/business listing changes before the client actively searched for a mover.

The gap

Marketplace platforms only list leads after users fill out search questionnaires, meaning competitors are already in their inboxes. Prior to Lead2Move, there was no platform that aggregated same-day pending, sold, and lease signals from multiple networks at once.

The approach

Build a 24/7 background scraping pipeline that aggregates data from Redfin, Estate, and LoopNet, translates property statuses to unified move signals, and distributes them exclusively to subscribers based on claimed zip-codes.

02 — Mover Workspace

Movers get exclusive, target-rich lead dashboards

Movers claim territory by ZIP codes, monitor status changes, and filter or export leads in seconds. Every screen below is live in production.

Primary Signals

Residential Pending Move Detection

Homebuyers entering contract represent the highest-intent move signals. The Redfin Pending dashboard displays newly pending listings within the subscriber's claimed territories, featuring exact address data and transaction date.

  • Real-time pending status updates within claimed ZIP codes
  • Accurate pricing and listing history audit trail
  • Direct CSV export options for direct-mail campaigns

Commercial Feeds

LoopNet Commercial Listings Integration

Movers can target corporate and retail office relocations by monitoring commercial listings. The LoopNet module fetches commercial properties marked as active, leased, or sold, facilitating B2B relocation outreach.

  • Filters commercial listing updates by ZIP code boundaries
  • Captures business office and retail relocations
  • Includes square footage and property class parameters

Multi-Network Feed

Estate.com Residential Property Feeds

Integrating Estate.com ensures a wider coverage network. This module tracks home listings and captures additional move signals that may not show up on standard consumer listing platforms.

  • Tracks listing details and property attributes
  • Auto-matches to claimed target cities
  • Provides daily export logs for offline teams

Pre-Sale Alerts

Redfin "Contingent" Property Changes

A property marked contingent is an early-stage move signal. Movers use these alerts to send marketing materials before the homebuyer reaches the final contract signing phase, securing early-bird booking advantages.

  • Identifies listings moving from active to contingent
  • Saves listing price and historical records
  • Assists in direct-mail pre-targeting workflows

03 — Admin Control Plane

Scraper diagnostics and global lead control

Superadmins monitor scraping daemon logs, configure subscription tiers, audit raw property listings, and oversee platform performance statistics.

Diagnostics

Scraper Log & Executions Console

The core control hub for the background scraping engine. Admin users inspect execution times, memory limits, scrape success rates, and live stderr/stdout outputs for Zillow, Redfin, Estate, and LoopNet tasks.

  • Real-time scraper status indicators and queue logs
  • Custom execution triggers for emergency data fetches
  • Scraper run memory and CPU optimization profiles

Rental Leads

Redfin Lease Transactions Feed

Auditing lease transactions provides movers with high-frequency rental lead updates. The system tracks rental house and apartment listing status changes, offering leads for residential moving teams.

  • Lists landlord and property manager details where available
  • Identifies rental price shifts and lease sign events
  • Tracks lease details and historical change logs

04 — Architecture & Guardrails

Built for performance and reliability

To pull data consistently and safely distribute matching leads, the platform relies on background daemons, rate limiters, and memory-safe streaming.

01

ZIP Code Validator

Validates and gates claimed ZIP codes per subscription tier, preventing boundary overlaps.

02

Rate Limiter & Rotate

Custom user agent strings and rotating proxies prevent scraper blocks.

03

Redis-Backed Queues

Handles real-time listing matches without stalling user UI threads.

04

Chunked CSV Stream

Streams historical exports chunk-by-chunk to prevent out-of-memory errors.

05

Stripe Webhook Listener

Listens to card cancels and plan shifts, adjusting ZIP bounds automatically.

06

Multi-Tenant Isolator

Data isolation scopes protect tenant claimed-leads from cross-account leaks.
