Two agents. One phone number.

Each agent is built on your own calls, your prices, your slots and your tone. They do not read from a generic script, and they say who they are.

Sales agent

Answers
Enquiries about price, availability, timings, location. Qualifies the caller in two or three questions.
Books
Appointments, site visits, demos and call-backs straight into your calendar or CRM.
Follows up
WhatsApp confirmation with the details, and a reminder before the slot.
Hands off
Warm transfer to your salesperson the moment a caller wants a human, with a one-line summary.

Support agent

Answers
Order status, delivery windows, returns, opening hours, how-to questions from your own knowledge base.
Resolves
Reschedules, cancellations, address changes, and simple account changes with your systems.
Escalates
Angry, medical, legal or payment-dispute calls go to a person immediately, with the transcript.
Reports
Every call transcribed and tagged. You read the morning summary, not the recordings.

Live in 24 hours.

Three steps. Most businesses are taking calls with their agent the day after they write to us, and nothing changes for your callers until you say so.

Step 1

Share

Send us your business documents if you have them, or a few of your call recordings. Our models learn your business from them: what callers ask, your prices, your slots, your tone.

HOUR 0
Step 2

Build

Your agent is built around your specific pain points, whether that is missed calls after hours, the same ten questions all day, or bookings lost in WhatsApp. You test it on your own phone.

HOURS 1 TO 20
Step 3

Live

Forward your number, or take a new one from us. Your agent answers the next call, and every call after it.

HOUR 24

What we refuse to build.

These are the reasons callers hate phone lines. We designed the agents so none of them can happen.

Send the number you use for sales or support and roughly how many calls it gets in a day. We will call it, listen, and reply within one working day with what an agent would change.
