finally found one that actually works

We had thousands of old numbers sitting in spreadsheets and needed to verify which ones actually had active WhatsApp accounts before starting outreach. ValidNum cleaned the whole list super fast. Being able to filter out standard profiles and isolate WhatsApp Business accounts is a huge plus for targeting.
