Building an AI Support Inbox for How WhatsApp Teams Actually Work

Most customer-support software starts from an email-shaped assumption: messages arrive one at a time, belong to one person, and wait patiently in a queue.

WhatsApp does not work like that.

A customer may send a photo, then a voice note, then three short follow-ups. A team may need to jump between direct messages and busy groups. Someone has to take over a conversation without asking the customer to repeat everything. And when automation answers at the wrong moment, it does not feel helpful — it feels intrusive.

That was the problem behind Hallo Zetta: build a shared WhatsApp customer-care inbox where AI can handle routine work without pretending humans are no longer needed.
