Kimble ·Products/AI Receptionist
Flagship product

An AI receptionist,
built as a workflow.

Every inbound call is a typed event with deterministic steps: classify the caller, check availability, book the slot, write the CRM, page the team, log the transcript. Bilingual, always on, observable end-to-end.

§01 · Architecture

The receptionist stack, tier by tier.

Five tiers, explicit contracts between each. Every call is a traced execution across the whole stack; every failure has a known fallback.

§03 · Industry fit

One core. Outputs defined by you.

Same engine, tuned to the calls your customers actually make. The outcomes column isn’t a menu, it’s a starting point. Everything downstream is scoped with you during discovery.

01
Plumbing & HVAC

Emergency dispatch · same-day triage · quote + book

Whatever your intake flow needs, calendar, CRM, dispatch, pager, SMS.

02
Electrical

Line-item quote · follow-up · schedule

Defined during discovery, CRM deal, price sheet lookup, booking, quote email.

03
Cleaning & housekeeping

New intake · recurring cadence · add-on services

Recurring calendar, contact, service details, SMS confirmation, whatever else you want.

04
Landscaping

Seasonal enquiry · package upsell · site-visit scheduling

Sales sequence, CRM deal, calendar hold, price proposal, scoped with you.

05
Auto & trades

Estimate intake · drop-off window · status updates

Any output your shop management system supports plus custom hooks.

06
Health & wellness

New patient intake · appointment · insurance screening

EHR / intake form writes, scheduling, reminders, compliance-aware flows.

07
Professional services

Consult request · document intake · referral capture

CRM write, document link, consult booking, internal alerting.

08
Hospitality & food

Reservation · catering quote · waitlist · loyalty

POS, reservation system, email sequence, SMS, defined with you.

Not on the list? The engine is vertical-agnostic, what we tune is the prompt, the allowed actions, and the outputs. If your industry isn’t here, we’ll scope it on the demo call.

§04 · Integrations

API-first. If it has an endpoint, we connect it.

§05 · FAQ

Technical questions, technical answers.

The objections we hear most often, answered the way the engineer who built it would.

Seven deterministic steps: classify the caller, verify or collect contact info, check calendar availability, propose and confirm a slot, write the booking, page the team, and log the transaction on an append-only audit spine. Every step is typed and traceable.

Production-grade natural voice tuned for conversational pacing, with bilingual English + Spanish and automatic mid-call language switching. Most callers don't flag it as AI, but if asked, the agent discloses.

Yes. 24/7 per-call monitoring is included with every receptionist deployment. We watch live traces, surface anomalies as they happen, and can intervene mid-call where the setup allows. You get a paged alert within seconds of anything unusual.

Hard failover. If the agent can't execute its action contracts, the caller is either transferred to a configured human number or offered a callback window, and your team is paged within seconds. Full transcript is retained for review.

Yes. The agent reads your live calendar (Google, Outlook, Jobber, Housecall Pro, ServiceTitan, etc.), confirms the slot with the caller, and writes the event. The booking lands in your calendar before the caller hangs up.

No. Kimble provides the models, the voice engines, and the prompt engineering. You provide the business. We handle every layer of the automation stack and tune the outputs to match how you actually run calls today.

Month-to-month, term contract (6 or 12 months, discounted), or annual upfront (most discounted). All tiers include the same build, the same operating SLA, and 24/7 monitoring. Specifics on the demo call once we've scoped the deployment.

7–14 business days end-to-end. Day 1 is a 30-minute discovery call where we spec the right workflow for your business. Days 2–10 are integration wiring, sandbox runs, and tuning. Then we forward your line and operate alongside you on the first real calls.

Per-tenant isolation in an audited datastore, encryption at rest, column-level encryption on sensitive fields, and append-only audit logs with UPDATE / DELETE revoked at the role level. Recordings are encrypted and access-scoped.

The agent offers an immediate transfer or a callback window from a human on your team. The exact fallback is configured during discovery. Nobody gets a dead-end.
