Ready when you are
Uses your microphone. Talk like a customer: ask a price, describe a problem, or book a visit.
A fictional company. Bookings go into a practice schedule and nobody is contacted.
The call you miss is the job your competitor books.
Heat waves bury your phones
When it's 100° outside, every homeowner calls at once. The ones who reach voicemail call your competitor next.
No-heat calls come at night
Furnaces fail on the coldest nights. Callista dispatches your on-call tech while the homeowner is still on the line.
A missed call can be a $10,000 system
Replacement leads are the biggest tickets you get. They deserve an instant answer and a booked estimate.

Questions owners ask
Will customers know it's an AI?+
Yes. It introduces itself as your company's AI assistant. Homeowners care far more that someone picks up, knows your prices and fees, and gets a tech out.
How does it handle emergencies?+
It asks the right questions, gives safety steps for gas, CO, flooding and electrical issues, checks the address, then alerts your on-call tech instantly with the customer's details. You set your after-hours fee and what counts as an emergency.
Can it quote prices?+
It quotes what you give it: diagnostic and trip fees, after-hours fees, maintenance plans and financing. It never invents a repair price. It books a visit or a free estimate instead.
Does it work with ServiceTitan, Jobber, Housecall Pro or GoHighLevel?+
GoHighLevel syncs natively: Callista reads your real calendar availability and books straight into it. Every booking can also go out by webhook or Zapier to Jobber, ServiceTitan or Housecall Pro, where your plan and their API allow.
Do I need a new phone number?+
No. Customers keep calling the number on your trucks and Google profile. You forward calls to your Callista line after hours, when you're busy, or all the time.
What if it doesn't work for my business?+
Book a job in your free trial, or you don't pay. If Callista hasn't booked you a single job by the end of your 14 days, we add 14 more free days. If it still hasn't, we cancel before you're ever charged.
How long does setup take?+
About ten minutes. Paste your website, check what it learned, set your service area and on-call contact, and forward your calls. You can test it before any customer does.
