Here's where your money is walking out the door

You're paying good money to make the phone ring. Then this happens:

Direct call
Somebody calls during a job. It rings out. They hang up and call your competitor.
85% never call back
Website form
A lead fills out your form at 9pm. You see it at 7am. They already booked someone else.
Booked someone else
Facebook lead
You paid for that lead. Nobody called them back fast enough. Gone.
Paid for it, lost it
Angi lead
Angi sends the same lead to 8 contractors. You call third. The job's already taken.
First caller wins
A 2-truck shop loses around this much every year just to calls and leads nobody got to in time. You'll never see it on a bill. That's what makes it dangerous.

How much are missed calls costing YOU?

Drag the slider to how many calls you miss on an average day. We'll do the honest math — not every missed call is a lost job, so we don't pretend it is.

The honest math: not every missed call is a job. We assume 85% of missed callers never call back, and of those, about 35% would have actually booked — then multiply by your average job value. Conservative on purpose. The real number is usually worse.
Now put someone on every one of those calls

How it works

You don't have to learn anything new

Day 1–3

We set it all up

The whole thing is built for you. Up and running in 3 days. You don't touch a thing.

From day 3

It answers and books

Calls and leads go straight into your calendar — your tools or one we set up. Nothing falls through.

Every morning

You get the rundown

Who called, what got booked, what we saved you. One quick message. That's it.

Founding partners

Why we only take a handful of new shops a month

Every ClusterX setup is built by hand and tuned to how your shop runs — so we cap how many we onboard at once to keep it white-glove. Get in this round and you lock advantages the shops after you won't:

Locked for life

Founding pricing

Lock the lowest rate we will ever offer. It never goes up — not when we raise prices, not ever.

White-glove

Built around your shop

We set up and tune every call flow to how you run jobs, price diagnostics, and dispatch — not a generic template.

Direct line

Founders on speed-dial

You talk to the people who built it. Tweaks happen same-day — not buried in a support queue.

Want proof it's good? That recording above is a real ClusterX call. Replay it →

Works with your setup

Keep the tools you've got. Or let us set you up.

Either way, you don't change how you work and you don't learn anything new.

You already have tools

We plug right into them

Booked jobs drop straight into the system you already use. Your office runs exactly the same — there's just nothing falling through the cracks anymore.

We set one up for you

Running on a cell phone and a notebook? No problem. We'll give you a clean, simple system to hold your jobs and customers — set up for you, included, nothing for you to figure out.

Our guarantee

If ClusterX doesn't book you more jobs than it costs in your first 30 days, you don't pay — and we keep working free until it does.

And if you ever want out, we refund every dollar — setup included, no questions asked. We only win when your phone turns into booked jobs, so the risk is 100% on us.

Before you ask

Straight answers

Will my customers know it's AI?

Most can't tell. It sounds natural, knows HVAC, quotes your diagnostic fee, and when a call really needs a human it escalates to you. Best way to judge — book the demo and have it call your own cell.

What if it can't answer something?

It handles the vast majority of calls — booking, pricing questions, no-heat and no-cool triage, scheduling. Anything outside its scope routes to you in real time with a full call summary, so nothing slips.

Do I have to change my phone number or software?

No. We forward your existing number, so customers dial the same line. Jobs drop into the tools you already use — or one we set up for you.

How long until it's live?

3 days. We build the whole thing for you. You don't touch a thing.

What's the catch with the guarantee?

None. Use it a full month — if it doesn't work for you, every dollar comes back, setup included. The risk is entirely on us.
