The calls you miss don’t
leave messages. They leave.
When a small business misses a call, the caller usually doesn’t wait: industry research finds roughly 80% of callers who reach voicemail hang up without leaving a message (Marchex), and 62% of callers who can’t get through contact a competitor instead (PATLive). The loss is silent — there’s no record of the job that went elsewhere.

It never shows up in a report. There’s no voicemail, no note, no record of what the job was worth — just a competitor’s phone ringing across town. The loss is completely silent, which is exactly why it never gets fixed.
We built Tetra to make that loss visible — then eliminate it.
Put a number on the silence.
Pick your industry and be honest about the calls that ring out while you’re with a customer, on a job, or closed for the night.
Likely walking out the door every month:
$5,600 – $14,000
3 missed calls × 30 days, counting only half as new business × the 62% who book elsewhere × $200–$500 per detailing job. A deliberately conservative estimate — you know your average ticket.
Tetra starts at $199 a month. See pricing ↓
Live on your line in 24 hours.
Getting an AI receptionist takes one day, not one project: you fill out a ten-minute form, we build and test your agent with you, and your calls forward to it — on the number you already have. You keep your number, your callers dial what they’ve always dialed, and there is zero technical work on your side.
-
1Tell us about your business
A ten-minute form: your services, prices, hours, and how you want calls handled. That’s the whole job on your end.
-
2We build your agent
Greeting, services, prices, FAQs, booking rules, escalation — trained on your business, in your words.
-
3You test it yourself
Call your own agent. Try to trip it up. We tune it until you’d trust it with your best customer.

4Go live
Your calls forward to your agent — all of them, or only the ones you can’t catch. Nothing to install, nothing to learn.
Built for businesses that live on the phone.
Tetra builds industry-specific AI receptionists for salons and spas, auto detailing shops, HVAC and home services, gyms, restaurants, and independent hotels. Claire and Aaron aren’t generic receptionists — each deployment is trained on one industry’s calls, software, and vocabulary.

Zero missed calls since go‑live.
A detail shop runs on two hands, and both are usually holding a polisher. For years the phone rang in a coverall pocket — answered when possible, returned at closing, and sometimes just… gone. A ceramic-coating job books with whoever picks up first. That’s the business.
Now Aaron answers the shop’s line. He greets callers by the shop’s name, quotes realistic ranges by vehicle and condition, captures what the customer drives, what they want, and when they can drop it off — and the owner gets a text summary before the caller has even put their phone down.
Since go-live, the shop hasn’t missed a single call. Not during jobs, not at lunch, not at 11 PM. The owner reads the day’s call log the way you’d read a booking sheet — because now, that’s what it is.
Deluxe is our first live deployment, and we’re proud of that. We’re now onboarding our first cohort of clients — the next case study on this page could be your line.
Pricing, published.
Tetra costs $199, $349, or $549 a month depending on call volume, plus a one-time setup fee of $300–$800 that covers building and tuning your agent. Every plan is month-to-month with no contract. Most of this industry hides its numbers behind a sales call — we’d rather you know them before we ever talk. (Comparing options? See our full cost guide.)

Fair questions, straight answers.
Honestly — does it sound like a robot?
You already have the best answer we can give: the demo at the top of this page is the same voice technology we deploy for clients, live and unedited. We won’t claim it’s indistinguishable from a person — we’ll just hand you the phone and let you judge. That’s why the demo requires no signup.
What if a caller really needs a human?
You set the rules during onboarding. Your agent can transfer urgent calls straight to your cell, take a detailed message and flag it as priority, or give after-hours callers your emergency procedure. Callers who need a person get to a person — the difference is that everyone else gets helped instead of hitting voicemail.
Do I have to change my phone number?
No. You keep the number on your storefront, your van and your Google listing. Calls forward to your agent — every call, or only the ones you can’t catch (busy, no answer, after hours). Turning it off is just as simple, and the number stays yours either way.
Does it book into my calendar or booking software?
We configure booking around whatever you run — GlossGenius, Vagaro, Square, Housecall Pro, Jobber, Mindbody, OpenTable, or a plain Google Calendar. Depending on what your software allows, that means booking directly, holding a slot for your confirmation, or capturing everything and texting the caller your booking link. We map this with you during onboarding so it fits how you actually work.
Am I locked into a contract?
No contracts. Plans are month to month and you can cancel anytime — the one-time setup fee covers building and tuning your agent, and the monthly fee only continues while you want the service. If you leave, call forwarding switches off and your line works exactly as it did before.
Is recording calls even legal?
Yes, with proper disclosure — and we set that up for you. Several states, including Pennsylvania, require all parties to consent to recording, so your agent is configured with a clear disclosure appropriate to your state. Recordings and transcripts belong to you, for reviewing calls and improving your agent.
What happens if I go over my plan’s call volume?
Nothing surprising. We watch your volume, we’ll flag it before you ever hit the cap, and we’ll talk about whether a bigger plan makes sense. You will never open a surprise bill from us.
How much does an AI receptionist cost?
For small businesses, AI receptionists generally run $200–$600 a month. Tetra’s published pricing is $199, $349, or $549 per month depending on call volume, plus a one-time setup fee of $300–$800 that covers building and tuning your agent. There are no contracts and no per-minute charges. For a full breakdown — including how that compares with human answering services and hiring a receptionist — see our AI receptionist cost guide.
What’s the difference between an AI receptionist and an answering service?
A traditional answering service puts a human operator on your line, usually billed per minute, and in most cases takes a message for you to return. An AI receptionist answers instantly at any hour for a flat monthly rate, holds the whole conversation, and can book the appointment on the spot instead of taking a message. Human services are still the better fit for delicate, high-judgment conversations. We wrote an honest side-by-side: AI receptionist vs. answering service vs. voicemail.
