CTO and cofounder, Kredentic
WatchTower
Protects businesses from impersonation fraud on Google Maps. Automated detection, evidence collection, and takedown workflows that close cases before customers get scammed. Built at Kredentic.
A Kredentic product. B2B SaaS that watches Google Maps around the clock for fake listings that impersonate real businesses. Built for the Ghanaian market, where scammers copy a business listing and swap in their own phone number.
The scam is simple: copy a real business name and address onto a Maps listing, replace the phone number, and wait for customers to call. WatchTower automates the monitoring. A Python detection engine scans listings across 22 Ghanaian districts and scores each one for fraud using three signals. A phone number mismatch carries 70 points, name similarity through RapidFuzz fuzzy matching adds 20, and a missing verification badge adds 10. Anything above 80 opens an incident.
When a listing triggers, Playwright opens a headless browser, loads the Maps page, and captures a full screenshot before anything can change. The screenshot goes to Supabase Storage and the link goes to the business owner on WhatsApp through Twilio. The Next.js dashboard tracks every incident from detection to takedown, and Supabase Realtime keeps it current without polling.
