What the agents do every day.

Three of the workflows we build, drawn as they run. Each one is illustrative and opens the product that runs it.

  • Answers every call, day or night.

    An after-hours caller is answered from your approved information, booked, and sent a confirmation.

Voice agents and outreach. One CRM. Your team at the end.

Seven products on two lines. Voice agents handle the conversations; outreach automation starts them. Both write to the same CRM, and both hand to a named person.

Where most teams start.

Each row is one workflow: what sets it off, what runs, and the person it lands with.

How a build goes: audit, connect, rehearse, go live.

Every build runs the same route. It starts on one short stretch and extends only when that stretch works.

  1. Map the calls and leads you lose

    Tell us which calls go unanswered and which leads go cold. We map the volumes, the questions, the rules, and the point where a person takes over.

  2. Connect your systems

    Your CRM, calendar, and phone line are connected, and contacts are enriched so each conversation starts with context.

  3. Write, voice, and rehearse

    Scripts, sequences, and the agent's voice are drafted with you and tested against difficult calls before anyone hears them.

  4. Go live on one stretch

    The system launches on a limited scope. Replies are sorted, meetings booked, and every handoff reaches your team with a note.

Four rules every build keeps

  • Your accounts, your data

    Phone numbers, sending domains, mailboxes, and CRM records stay in your name.

  • Consent and disclosure first

    PDPA consent, Do Not Call checks, AI disclosure, and opt-outs are set before launch.

  • Rehearsed before it talks

    Difficult calls, accents, and awkward replies are tested before any customer hears the agent.

  • One record per contact

    Calls, email, LinkedIn, SMS, and WhatsApp touches are logged against the same contact.

How we handle data, access, and review

Your accounts, your data, your rules.

Phone numbers, sending domains, mailboxes, and CRM records stay in your name, so nothing is locked inside our tools. Every integration is confirmed during scoping.

  • Phone lineYour existing number, or a new one
  • SMS and WhatsAppConfirmations and follow-ups
  • EmailYour own domains and mailboxes
  • LinkedInDrafted by AI, sent by your rep

  • WorkspaceGoogle Workspace, Microsoft 365
  • Your teamA named owner for every handoff

Built for teams that live on the phone.

Pick the team closest to yours. The exchange is illustrative; the handoff at the end is how every line finishes.

Caller

Hi, I'd like to book a dental check-up, ideally this Saturday morning.

AI assistant

I can do that. Saturday has 9:30 and 11:00 open. Which would you like? I'll send an SMS confirmation once it's booked.

Hands to · Front desk

Sees the booking in the morning with any notes the caller left, and confirms anything outside the booking rules.

Every call that needs judgement reaches a person.

When a call needs a decision, the agent stops and writes a note: what the caller wants, what is already done, and what is needed from the person who takes it from here. Your team reads it in an inbox like this one.

What does AI Xvantage build?

Two things. AI voice agents that answer and make calls, and outreach automation that researches prospects and runs email, LinkedIn, and call sequences. We design, build, and run both on your own accounts, and every workflow hands off to a named person on your team.

Is this software we sign up for, or a service?

A done-for-you service. We build on proven voice and outreach platforms plus the tools you already use, then run and improve the system with you. Accounts, data, and configuration stay yours.

Will people know they are talking to an AI?

Yes. Voice agents introduce themselves as AI assistants and offer a person whenever the caller asks. Outreach is sent from your team's accounts, in your voice, and approved by your team before it goes out.

How do you keep calls and outreach compliant?

Consent, Singapore Do Not Call Registry checks for marketing calls and messages, clear opt-outs, sending limits, and LinkedIn's own limits are designed into each workflow during scoping. Your team confirms the final position; this is not legal advice.

Which tools do you connect to?

Commonly HubSpot, Salesforce, Pipedrive, or GoHighLevel for CRM; Google or Outlook calendars, Calendly, or Cal.com for booking; Google Workspace or Microsoft 365 for email; and your existing phone line or a new number. Every integration is confirmed during scoping.

Where do we start?

With an AI workflow audit. Bring the calls you miss and the leads you lose. We map them, choose the first workflow worth automating, and send a scoped pilot in writing.

Your next booked meeting starts with one sentence.

Describe the calls or follow-up you want handled. We come back with the first workflow worth building and the person it hands off to.

Opens the audit form with this filled in. Nothing is sent until you submit it there. 0/500
