AI Voice Agents

What an AI voice agent actually is

Before anything else, here's what you're actually buying — not a buzzword, a specific piece of technology with a specific job.

This is not the phone tree you're picturing. An AI voice agent isn't a menu of “press 1 for sales.” It's a real-time conversation: the caller talks normally, the AI understands what's said, and it responds in natural speech — built specifically around your business, not a generic script.

1
A call connects
Someone calls your business, or the agent dials out to a number on your own list.
2
Speech becomes text
What's said is converted to text in real time, so the AI can actually understand the conversation, not just detect keywords.
3
The AI decides what to say
Using your business information, call scripts, and guardrails, the AI works out the right response — the same way a trained rep would.
4
Text becomes natural speech
The response is converted back into natural-sounding voice in real time, so the call flows like a conversation, not a robot reading a script.

Where this actually helps

We build voice agents for two specific jobs. If what you need doesn't fit either one, it's worth a conversation before you apply.

Customer Support

Answers common questions, handles routine requests, and routes or escalates what it can't resolve — available every hour you're not.

Outbound to Your Own List

Calls people who already have a relationship with your business — past customers, inquiries, bookings — so you're not paying a human caller to work a list you already own.

Before we build anything, here's what's required

This isn't fine print we hope you skip. These are the two non-negotiable rules behind every outbound agent we build.

Your list only — never cold calling. We build outbound agents to call your own list: people who've inquired, booked, bought, or otherwise have an existing relationship with your business. We do not build or support agents for purchased, scraped, or otherwise cold lists, for compliance reasons. If you're looking to generate net-new pipeline, see AI & Outreach Consulting instead.

Every call discloses it's an AI. We build AI disclosure into the start of every call, by design — the agent identifies itself as an AI, every time. We don't build agents that pretend to be human, and you're responsible for complying with your own jurisdiction's calling and AI-disclosure regulations on top of that.

Who this is built for

We work with fewer clients than most agencies because we go deeper. Before we look at options, be honest with yourself about whether this describes your situation.

This is for you if:

You want a voice agent answering customer support calls 24/7, consistently
You have your own list — people who've inquired, booked, or bought from you — you want called
You're comfortable with the AI disclosing itself as an AI on every call
You understand usage costs (call minutes, AI platform fees) are billed separately from the build
You want a working, tested agent, not just a demo
A standard support or outbound agent covers your use case

This is not for you if:

You want to call a cold, purchased, or scraped list — we don't build or support this
You want to hide that it's an AI from the people you're calling
You're looking for net-new lead generation — see AI & Outreach Consulting instead
You need a highly custom, multi-system voice build beyond a standard agent
You expect zero usage costs beyond the build fee

What inaction is actually costing you

This is the part most founders don't calculate. Not the cost of building a voice agent — the cost of every call that goes unanswered while you wait.

Missed calls are missed revenue

Every unanswered support or sales call is a customer talking to a competitor instead, not waiting for you to call back.

Hiring human callers is expensive and slow to scale

Training, turnover, and hourly costs add up fast for work an agent can do consistently from day one.

Slow follow-up kills conversion

Leads that go uncalled for even a few hours convert at a fraction of the rate of ones reached immediately.

After-hours and weekend gaps cost you deals

Customers and leads don't only reach out 9-to-5, but most support and sales teams do.

What we build — and why it works

We build your agent on the same voice AI stack you'd pay a specialist agency to set up — configured, tested, and handed over, ready to answer or make calls.

Build fee and usage costs are separate. We build and configure your agent on Vapi or Retell AI, with natural-sounding speech from ElevenLabs. Call minutes, AI model usage, and telephony are billed directly by those platforms based on your actual call volume — not included in our build fee. See the exact tools we use on our Our AI Stack page.

Agent Design & Scripting

Call flow, business information, objection handling, and guardrails, tailored to your support or outbound use case.

Voice & Telephony Setup

Built on Vapi or Retell AI, with a natural-sounding ElevenLabs voice matched to your brand.

Integrations

Connects to your CRM, calendar, or helpdesk, so the agent isn't operating in a vacuum.

Testing & Handover

Tested on real call scenarios before it ever reaches a real customer or lead, with a walkthrough on handover.

How it works

1
Apply
Tell us whether you need support or outbound, your call scenarios, and any systems to integrate with.
2
Build & configure
We design the call flow, build the agent on Vapi or Retell AI, and test it against real scenarios.
3
Launch & monitor
Your agent goes live, and we walk you through monitoring calls and usage going forward.

What's included

Call Flow & Scripting

Designed around your actual support or outbound use case, not a generic template.

Natural AI Voice

Built on Vapi or Retell AI with ElevenLabs speech — and AI disclosure on every call, by design.

One System Integration

Connected to your CRM, calendar, or helpdesk, included in the standard build.

Tested Before Launch

Run through real call scenarios before it ever answers or makes a live call.

Why SFC and not a call center or hiring callers?

A call center rents you a service that disappears the moment you cancel. Hiring means training, turnover, and hourly costs that scale with every call.

	Call Center / Human Hire	Six Figure Consulting
Cost	Hourly wages, training, and turnover costs that scale with call volume	One flat build fee, usage scales only with actual calls
Availability	Business hours, sick days, turnover	24/7, consistent, never off-script
Ramp time	Weeks of hiring and training before the first real call	Built, tested, and live before launch
Compliance	Cold-calling vendors are often vague about list sourcing and AI disclosure	Your list only, AI discloses itself on every call, by design
Ownership	You rent a call center's service — it disappears when you cancel	Built on your own Vapi/Retell AI and ElevenLabs accounts — you own it

Investments

One flat fee to design, build, and test your agent. Usage is separate, billed directly by the platforms based on your actual call volume — not something we mark up or bundle.

Get Started

Two separate costs — the build, and what it costs to run

The $2,500 build fee covers designing, building, and testing your agent. It does not include usage. Call minutes, AI model usage, and telephony are billed directly by Vapi or Retell AI and ElevenLabs, based on how much the agent is actually used — we'll walk you through estimated usage costs for your call volume before you commit to a build.

Need something more complex? We don't have an in-house team for highly custom, multi-system voice AI builds. Apply and tell us what you're looking for — we'll connect you with a partner from our network who specializes in it.

FAQ

Can you call a cold list we bought or scraped?

No. We only build outbound agents for your own list — people who've inquired, booked, bought, or otherwise have an existing relationship with your business. This is a compliance requirement, not a preference.

Does the AI tell people they're talking to an AI?

Yes. Every agent we build discloses that it's an AI at the start of the call, by design. We don't build agents that pretend to be human.

What's the difference between the build fee and usage costs?

The $2,500 is a one-time fee to design, build, and test your agent. Usage costs — call minutes, AI model usage, telephony — are billed separately and directly by Vapi or Retell AI and ElevenLabs, based on how much the agent is actually used.

How much do usage costs typically run?

It depends entirely on your call volume and average call length, and platform pricing changes over time, so we won't quote a number here. We'll walk you through estimated usage costs for your specific use case before you commit to a build.

What if I need something more complex than a standard support or outbound agent?

We'll connect you with a partner from our network who specializes in complex, multi-system voice AI builds. We don't have an in-house team for that scope — the standard build is what we build ourselves.

Is this a cold-calling service?

No. We don't do cold calling and we don't work with cold-call lists. This is a tool for your own customer support, or for calling people who already have a relationship with your business.

Who owns the voice agent after it's built?

You do. It's built on your own Vapi or Retell AI and ElevenLabs accounts, not ours.

How long does it take to build?

Most standard builds go live within 1–2 weeks of receiving your call scripts, business information, and any integration details.
