For appointment businesses, WhatsApp is the front desk: bookings, reschedules, questions, no-shows. We build assistants that live in it — booking clients, answering from your real prices and hours, chasing quiet leads — designed for English and Portuguese-speaking markets, with every message in your voice.
Clients book, move, and confirm appointments in the chat they already use — synced to your calendar.
Prices, hours, availability, directions — answered in seconds from your real information.
Quiet leads get chased and past customers get invited back, without you touching the phone.
One tap and you're in the conversation — the assistant steps back the moment you step in.
The AI Secretary inside Bia — our assistant suite for appointment-based businesses — is this capability, productized. Honestly labeled: in R&D.

We don't open with a build — we open with the Leak Report: a free first call, then a written diagnosis of your pipeline with a dollar figure on each gap. If this build isn't where your numbers say the money is, we'll tell you what is.
