# Merx
> Merx helps brands run compliant, two-way customer conversations on WhatsApp,
powered by on-brand AI agents.
Merx is built for retail and consumer brands (including beauty, fashion, wellness, and
specialty retail) that want to:
- grow WhatsApp opt-ins (with explicit consent),
- run lifecycle and campaign messaging as interactive conversations (not one-way
blasts),
- provide AI-assisted sales and support experiences,
- capture first-party and zero-party insights from conversations to improve
segmentation and outcomes.
