The business keeps its published number. A one-time call-forwarding code sends only unanswered calls to the service.

Missed-Call → Text-Back: the call you missed becomes a booking.
When a small business cannot pick up, the customer calls the next one. This product messages them on WhatsApp within seconds, has a short conversation in their language, and puts them on the calendar — while the owner is still on the other job.
How we made it
From the first conversation to the running product.

We sat with the people doing the work and wrote down how it runs today, and where it hurts.

Try it — you are the customer
Your business, answering on WhatsApp. Even at midnight.
Pick a business and chat with it. Watch what happens behind the scenes: details saved, bookings made, and anything about money or health passed to a real person who approves the reply.

The idea
Speed is the product.
The first reply has to arrive while the customer still has the phone in hand. So the first message is a pre-approved WhatsApp template sent from a dedicated fast queue, with no model call in front of it. The conversation that follows uses a fast, low-cost model; booking and consent are plain code.

What we built
Inside the product
Pick one to see it
Missed-call detection
Works with conditional forwarding or a tracking number, and starts the reply on a dedicated queue.
Conversation state machine
The model fills name, problem, address and urgency; parsing is defensive and every turn is checked.
Real availability
Two free slots from the business calendar, and a booking service that prevents double-booking.
WhatsApp rules built in
The 24-hour window, approved templates, opt-out, quiet hours and per-number caps are enforced in one gate.
Failover
A circuit breaker switches to a second model provider; SMS takes over when WhatsApp cannot deliver.
Gulf-ready
Arabic, a Sunday-to-Thursday week and local currency, with English and other markets from the same code.
See the flow
On the WhatsApp page, pick “Home maintenance” and start from the missed call.
