How it works

A process built for results

Clear milestones, constant communication, and zero surprises. Here’s how we get from idea to impact.

Step 01

Discovery & Success Criteria

We map your call flows, tools, and goals, and define what a great call sounds like.

01
Step 02

Build the Agent + Connect Data

We craft the scripts and voice, then connect your CRM, calendar, and systems with scoped access.

02
Step 03

Test + Simulate + Review

We run simulated calls, refine the responses, and review security before anything goes live.

03
Step 04

Launch + Monitor + Iterate

We go live with monitoring in place, then tune the agent based on real calls.

04

Proof & reliability

Proven results

Real outcomes from real call volume, more calls answered, more appointments booked, fewer leads lost.

01

Never Miss a Service Call

Case StudyHome Services

41%more booked jobs

AI receptionist answering 24/7.

Problem

An HVAC and plumbing company lost emergency jobs every night, after-hours and overflow calls hit voicemail and most callers hung up and dialed the next contractor.

Approach:

Deployed an inbound voice agent that answers on the first ring, captures the job details, prices common visits, and books the dispatch slot straight into the scheduling tool.

Outcome:

Emergency leads captured around the clock and a 41% lift in booked jobs, without adding a night dispatcher.

02

Turn Listing Inquiries Into Showings

Case StudyReal Estate

2.4xmore showings booked

Instant response to every listing call.

Problem

A brokerage's agents were in showings all day, so inbound buyers and renters went to voicemail, and hot leads were gone before anyone called back.

Approach:

Set up a voice agent that answers every listing inquiry instantly, qualifies budget and timeline, and books the showing into the agent's calendar with the property details attached.

Outcome:

Speed-to-lead dropped from hours to seconds, more than doubling showings booked and keeping agents focused on closing.

03

Cut No-Shows at the Clinic

Case StudyHealthcare

31%fewer no-shows

Automated reminder & reschedule calls.

Problem

A multi-location clinic was losing revenue to no-shows, and front-desk staff couldn't keep up with manual reminder calls or the flood of inbound scheduling requests.

Approach:

Added outbound voice calls that confirm, remind, and reschedule appointments, plus an inbound agent that books and triages routine requests, every result synced to the EHR.

Outcome:

31% fewer no-shows, fuller schedules, and front-desk staff freed from the phones to focus on patients in the room.

04

Faster Collections, Fewer Drop-offs

Case StudyFinance

28%faster collections

Compliant outbound payment reminders.

Problem

A lender's collections and loan-servicing teams couldn't make enough outreach calls, so payment reminders slipped and applicants abandoned half-finished applications.

Approach:

Deployed a compliant voice agent that places payment reminders, answers balance and status questions after identity verification, and follows up on stalled applications, logging every call to the CRM.

Outcome:

28% faster collections and more applications completed, with a full audit trail on every regulated conversation.

FAQ

Common questions

Everything you need to know before we start working together.

Most agents go live in days, not months. We start with one focused use case (like inbound reception), prove it on real calls, then expand to outbound and more workflows.

Yes. We use natural, low-latency voices and scripts tuned to how your business talks, so most callers don't realize they're speaking with AI. You control the voice, tone, and personality.

Both. The same agent answers incoming calls and places outbound calls such as appointment reminders, follow-ups, and lead qualification, all logged and measurable.

Yes. The agent reads and writes to tools like HubSpot, Salesforce, and Go High Level in real time, creating contacts, logging calls, and booking appointments straight into your calendar.

The agent detects when a caller needs a person and warm-transfers to the right team, with the context of the conversation, so nothing gets lost in the handoff.

Every call is recorded and transcribed with scoped, least-privilege access to your systems. We encrypt data in transit and keep you in control, so you can revoke access at any time.

Pricing is simple and usage-based. You pick a monthly plan (Starter, Growth, or Professional) with a block of included call minutes, and only pay overage if you go beyond it. Plans scale as your call volume grows.

Yes. The agent detects the caller's language and responds fluently, switching naturally mid-call, so you can serve more customers without staffing a multilingual team.

Yes. We route your current number to the agent, so callers reach the same line they always have, with no change on their end.

The agent answers every call, day or night, and handles many at once, so nights, weekends, and volume spikes never hit a busy signal or voicemail.

Full control. You shape the scripts, tone, and guardrails so the agent stays on brand and on policy, and we update its answers as your business changes.

That's exactly what the discovery call is for. We map the calls you handle today, find the highest-impact ones to automate first, and plan your go-live before any build starts.
