Hi — this is Sofia from YourBrand. Got a minute?

CUST

Sure, what's this about?

AI

You filled out our form Tuesday — looking at the Pro plan?

CUST

Yeah, for our 8-person agency.

AI

Perfect. Want me to grab a 20-minute slot with our specialist?

CUST

Tomorrow afternoon works.▌

The problem

Most leads die between the form fill and the first conversation.

Speed-to-lead is the single biggest predictor of conversion. Almost nobody is fast enough — because humans need to sleep, eat, and do other work.

01

Inbound calls go to voicemail.

A lead calls at 6:42 PM. Or Saturday. Or while you're on another call. By the time you call back, they signed with someone else.

02

Outbound is a grind nobody does.

Reps hate dialing. Lists go stale in 48 hours. The warm leads from yesterday's form fills are cold by Monday — and gone by Tuesday.

03

Calendar tag and CRM hygiene.

Even when calls connect, half don't make it onto a calendar, and almost none make it into the CRM with notes. The pipeline is leaking.

How it works

From form fill to booked meeting — in four moves.

Configure once, plug into your stack, and pick up every lead the moment they raise their hand.

01

Train the agent on your script.

Upload your qualifying questions, objection handling, product details, and tone of voice. The agent learns your playbook in a single onboarding session.

Qualifying script
1Confirm interest in Pro plan
2Team size? (need 5+)
3Timeline? (next 60d)
4Budget approved?
5Decision maker on call?
02

Plug in your phone, calendar, CRM.

Number ports in days. Calendars (Google, Outlook, Cal.com) auto-sync. CRM (HubSpot, Salesforce, Pipedrive) gets every call with full notes and recordings.

Yeah, but actually we're already on Salesforce — does this replace it?

Great question — we don't replace Salesforce, we sync to it. Want me to show you how?

Teams that stopped letting leads slip through the cracks.

Real outcomes from teams using AI Caller. Quotes & metrics are placeholders until we plug in customer data.

We were missing 40% of after-hours calls. AI Caller picks up every single one — and books more than half. The math made itself.

Our SDRs hated cold dialing. Now AI Caller runs the top of the funnel and our reps only get the qualified calls. Morale up, pipeline up.

FAQ

Questions we hear a lot.

How is this different from a chatbot or IVR?
IVRs are menus ("press 1 for sales"). Chatbots are text. AI Caller is a real-time voice agent that understands open-ended speech, follows your script with judgment, and handles interruptions and objections like a human. Callers don't know they're not talking to a person — until you tell them.
Will the agent sound robotic?
No. We use the latest neural voices (you can pick from 12+ presets, or clone a custom voice from a 30-min sample). Latency is under 500ms end-to-end, so conversation flows naturally. Most of our customers run an A/B before launch — the AI consistently scores higher on "felt natural" than their own SDRs.
How does it work in Portuguese and Spanish?
Native-fluent in both — including LATAM Spanish (Mexican, Colombian, Argentinian) and Brazilian Portuguese. The agent auto-detects the caller's language from the first sentence. Scripts are written once in your source language and we translate + culturally adapt.
What about compliance? TCPA, DNC, recording disclosures?
AI Caller handles TCPA (US), DNC scrubbing, recording disclosures, and consent logging out of the box. For outbound campaigns we suppress flagged numbers automatically. For EU calls we're GDPR-compliant with regional voice processing.
Can it transfer to a human?
Yes. Warm transfer with full call context (transcript + summary + intent). You set the rules — high-intent leads, complex objections, abusive callers, anything. The agent is a force multiplier, not a replacement.
How long does it take to launch?
A week. Day 1–2 we ingest your script, qualifying questions, and product details. Day 3–4 you tune the agent against test calls. Day 5 we port your number. Day 7 you're live, picking up real leads.
