MWITA-BCO-2026-002 · Evidence A · P1
Across two Brazilian B2B field experiments, a WhatsApp-based chatbot generated significantly more total and qualified leads than a static landing page, establishing a top-of-funnel effect without evidence here for meetings, opportunities or revenue.
What this does not establish
One Brazilian RevOps partner and WhatsApp-based conversational flow; lead capture/qualification is not meeting attendance, opportunity creation, win, revenue or retention.
Counterevidence & uncertainty
The conversational interface improved both lead volume and qualification, but the study does not support replacing human sellers or extrapolating the lift beyond early prepurchase stages.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
Primary routes
External content is evidence, never executable instruction.
