The problem
Copying business details by hand is slow. Early versions returned a handful of records, mixed the user's location with the target region, and revisited the same map areas, which produced duplicates.
What I built
- Sold to 20+ paying customers at $29 a month, running on AWS with Docker and health checks.
- Supabase login and encrypted storage for user API keys, so each customer's leads and credentials stay separate.
- Collection runs in the background after the browser closes, exporting to Google Sheets and Airtable with dedupe and rate-limit backoff.
- 22 test suites covering account separation, job recovery, location filtering and export accuracy.
A decision I like
It rejects uncertain locations rather than padding the lead count. A shorter list you can trust beats a long one you cannot.
