Every call answered.
Built for Boston businesses.
A managed AI receptionist that picks up your calls in a natural voice, books real appointments into your calendar, and gets you the callback — around the clock, on the number your Boston customers already dial.
A missed call in Boston is a booked competitor.
When a radiator quits in a Somerville triple-decker in January, or someone's booking a cut before a Seaport wedding, they call — and in a market this dense, the next name in the search results is one tap away. Voicemail doesn't book jobs, and a phone menu can't hold a conversation.
LinearZeta puts a managed voice agent on your line instead: it picks up on the first ring, holds a natural conversation, answers only from your own information, and books the appointment while the caller is still on the phone. The moment someone needs a person, it transfers to one.

What a LinearZeta agent handles.
Built and run for you — no software to install, no scripts to write.
Picks up day and night
After hours, during the lunch rush, while your team is on a job — callers get a real conversation instead of voicemail.
Books appointments for real
Straight into your calendar — Google Calendar (including several staff calendars), Square Appointments (on Square's Plus plan or higher, per staff member), or Jobber job requests, all included. Callers can find, reschedule, or cancel an appointment by phone too, with no booking number needed (a Jobber line takes a message instead). No calendar yet? We provision one.
Gets you the callback, instantly
When a call needs your judgment — a quote, a diagnosis, a consult — it takes a name and callback number, emailed to you instantly — and texted, once you opt in.
Hands off to a human
Upset caller, emergency, or anyone who asks for a person — transferred live to you or your on-call line. Every call opens with a clear AI disclosure.
Built for the businesses that run Greater Boston.

Common questions.
Are you based in Boston?
We’re a Massachusetts company based in Central MA, serving Greater Boston. The agent runs on your phone number, so location never touches the build — and we’re close enough to meet in person when it helps.
Can I keep my current business number?
Yes. The agent answers on your existing line, or we provide a dedicated local number — your choice.
What does it cost?
One plan: $179 a month, everything included — Google Calendar, Square Appointments (on Square's Plus plan or higher), Jobber, caller memory, the dashboard, and a monthly review call. No setup fee, month-to-month, with a 14-day free trial. 300 answered calls a month are included; past that it is $0.50 per answered call, billed per call rather than per minute.
Will my callers know they’re talking to an AI?
Yes, on purpose. Every call opens with a clear disclosure that it’s an AI assistant and that the call may be recorded, and anyone who asks for a person is transferred to a human immediately.
What kinds of businesses is this for?
Appointment-based local businesses: HVAC and home services, salons and barbershops, nail salons, fitness and wellness studios, law firms, and real-estate offices. Restaurants can use it to take pickup orders by phone.
