Never miss a job call again.

Giantz builds AI receptionists and automation for businesses that live on the phone. Yours answers in your business name, books the visit and sends you the lead, even at 2 a.m. on a roof-leak night.

How it works

From a ringing phone to a booked job, without you picking up.

  1. 1

    Tell us about your business

    Your name, trade, service area and hours. That is all the receptionist needs to sound like you.

  2. 2

    Hear it answer as you

    Call the demo line and it greets callers with your business name. See exactly what your customers will experience.

  3. 3

    Get the lead card

    Every call becomes a clean lead card: who, where, what, how urgent, and the visit it booked.

AI Receptionist

Trained for your trade, not a generic script.

Pick a trade to see what the receptionist asks and what lands in your inbox. Built first for home-service pros; it works for any business that lives on the phone.

What it asks

    Sample lead card
    Sample data, for illustration

    Answers in your business name

    Recognises your line or a demo code, then speaks as your company, with your services, hours and area.

    Books real appointments

    Offers open windows from your hours and never books the same slot twice.

    Lead card with transcript

    Name, phone, address, problem, urgency and the booked time, in one e-mail.

    Emergency aware

    Danger to life? It tells the caller to call 911 first. Urgent jobs are flagged so you call them back first.

    Honest by design

    It says it is an AI, never quotes prices, never takes card details and never discusses its instructions.

    Cost-safe limits

    Call-length and daily limits keep usage predictable. No surprise bills from a runaway call.

    Coming next Ring-you-first routing: your phone rings, and the AI picks up only when you cannot or after hours.

    What a missed call costs

    Put your own numbers in.

    Most owners know roughly how many calls go unanswered. Move the sliders to see the work that slips away each month.

    Beyond the phone

    Questions

    Straight answers.

    Will callers know it is an AI?

    Yes. The first thing it says is that it is an AI assistant and that the call may be recorded. We think honesty builds more trust than imitation.

    Can it quote prices or take payments?

    No. It collects the job details and books a visit. Prices and payments stay with you.

    What if it is an emergency?

    If someone is in danger it tells them to call 911 first. Other urgent jobs are flagged as emergencies on the lead card.

    Do I have to change my phone number?

    For the demo we use a dedicated line. Routing your own business number is part of what we set up with you; ring-you-first routing is the next feature we are building.

    What does it cost?

    The demo is free. Pricing for live service is being finalised with the first businesses we work with, so ask us and we will tell you plainly.

    Which languages and countries?

    English today, with US phone numbers first. Other languages are possible later.

    What happens to call data?

    Voice recording is off by default. We keep the text transcript and the lead so you can read it, for a limited time. Read the privacy notice.

    Can you build something custom?

    Yes. Multi-tenant SaaS, internal tools and automations are what we do beyond the receptionist. Tell us the problem and we will propose a prototype first.
