Booking data turned into retention revenue
An appointment-based business sat on years of booking history it had never activated. Retention and winback were spreadsheets and good intentions, while the ad platforms ran on cold audiences.
I built a reverse-ETL pipeline on GCP and BigQuery, modelled lapsed-visitor and high-value segments (proven on booking platforms like Mariana Tek and MindBody), and synced them to paid and email with winback flows that trigger themselves.
Lapsed customers became a reactivatable audience the business could actually market to.
