Listing Sentinel
The public internet, turned into curated, defensible, continuously maintained data.
Any list of information that exists in public web content — rental listings, business registrations, supplier prices, product catalogues, sales leads — Listing Sentinel collects it on a schedule, validates every record, links it to real-world entities, preserves evidence of what was published, and delivers it in the form you work in.
Engagement Models
Three ways to buy it
1
Buy the data.
Tell us what you want from the public web. We build the collection, run it on your cadence, and deliver the curated dataset — CSV, JSON, API, or written straight into your CRM. No software to run, no seats to license.
2
License the solution.
The full platform configured for your vertical: dashboards, alerts, scheduled reports, evidence capture, and exports, operated for you and accessed by your whole team.
3
White-label it.
The platform programmed for your specific need, carrying your brand. Your product, our engine.
The Platform
What every mode gets
Scheduled collection
From any public web source, with full raw capture preserved — page content, screenshot, PDF, and a cryptographic integrity hash for every record.
Validation you can audit
Every record passes schema and quality gates; failures go to a review queue, never silently dropped.
Entity resolution
Cross-source matching and de-duplication with a confidence score on every link.
Lineage on demand
Any record's full derivation, from source capture to final delivery, is replayable and displayable. When a number is challenged, you show its provenance; you don't reconstruct it.
Coverage transparency
Sources change and break; you hear it from us immediately, with repair tracked to closure. Never a silent gap.
Evidence-grade storage
Timestamped, hashed, immutable captures with chain of custody, for data that has to survive a hearing or an audit.
Delivery your way
Dashboards, alerts, reports, self-serve exports (CSV, Excel, JSON, PDF), REST API, or system write-back.
Single-tenant deployments
Your data in a dedicated environment, with Canadian-only data residency available (Microsoft Azure Canada Central and Canada East).
Editions
Configured for the work
Rental Compliance
Listing intelligence for regulators and enforcement teams: full-market rental listing monitoring across short-term rental platforms, long-term rental sites, classifieds, and marketplaces, with cross-platform operator matching, address identification, licence cross-reference, and hearing-ready evidence packages.
