Voice AI for the small businesses
that pick up the phone.

Sage Coastal designs and ships practical voice AI for service businesses across Southern California — receptionists that catch after-hours calls, qualify leads while you're on a job site, and route real urgency to the right person. Built for the realities of running a small operation.

What we build

Productized voice AI, built and tuned for your business.

We design voice AI tools the way they should be designed — scoped, specific, owned by you, and integrated with how you actually work. No generic chatbots, no enterprise sales theater, no surprise bills. Just a working tool that picks up the phone.

1

Productized AI receptionist

Our flagship offering: an AI voice agent that answers your phone, qualifies leads, books appointments, and hands you a clean summary. Two-week build, then live.

2

Custom voice and AI tooling

If your business has a specific workflow — a tricky intake process, a multilingual customer base, an unusual booking flow — we build the persona and routing for it. Same tech, custom config.

3

Implementation and tuning

We don't disappear after launch. Monthly retainer covers monitoring, persona iteration, and answering "why did it do that?" so the tool actually works in production.

Featured product

Sage — the AI receptionist for after-hours and overflow.

Your phones don't stop ringing when your front desk steps away. Sage answers naturally, qualifies the lead, books appointments where you allow it, and texts or emails you a clean summary. She doesn't replace your team — she catches what your team misses.

"Bright Smiles Dental, this is Brittney — how can I help you?"
Sage · configured per practice

A receptionist your team will like having around.

Sage runs in your existing phone system as a forwarding rule — no app to install, nothing for your staff to learn. After-hours and overflow calls route to Sage; she handles them in conversation, captures structured booking requests, and delivers them to you in the morning (or in real time via SMS for field-based businesses).

Configurable per practice: your business name, services, hours, insurance carriers, escalation logic. Your customers hear a name you choose, in a voice you pick. The AI is ours; the experience is yours.

From $2,500 setup + $500/mo · You bring your own OpenAI account · Usage runs ~$30/mo for typical after-hours volume

How an engagement works

Two weeks from "let's try it" to "she's answering your phone."

Step one

Discovery call

Twenty minutes, no charge. We learn what your business does, where calls go to die, and whether Sage is a fit.

Step two

Build & tune

One week to configure Sage for your business — services, hours, persona, escalation, voice. Daily check-ins.

Step three

Soft launch

One week running live with monitoring. We tweak based on real conversations until she sounds right.

Step four

Ongoing

Monthly retainer keeps her tuned, monitored, and improving as your business changes. Cancel anytime.

Pricing

Transparent, scoped, no surprise bills.

You bring your own AI provider account (OpenAI, ElevenLabs) and pay for usage directly to them at standard rates. We charge for our work — building, tuning, and keeping the system running for you.
