Enterprise AI agents.
Fully managed for you.
Others sell software. Callibre is the ecosystem.
Deploy enterprise-grade AI agents under your brand — with an in-house team of prompt builders and 24/7 in-channel support handling everything behind them. The platform plus the people.
Enterprise agents need more than a login.
They need a team.
This is what working with Callibre actually looks like. You close the client — everything after that happens in a Slack channel we build for you.
You sent two messages. The ecosystem did the rest — intake, knowledge base, prompts, QA, launch, and every 2 AM fix since.
You get a login.
- —You write every prompt yourself
- —Support means a ticket portal
- —Docs, Discord, and good luck
- —Broken agent = your late night
- —You are the fulfillment team

- ✓Broken agent = our fix, tonight
- ✓Fulfillment muscle behind every deal you close

The Full Ecosystem
Everything behind the saleA fulfillment engine behind every deal you close — so you can sign clients before you've hired anyone. The full operation, not just the AI.
The platform our team
runs under your brand.
Enterprise infrastructure underneath — voice, chat, white-label, GHL-native. Our specialists own every layer. Nothing labeled Callibre. Everything labeled yours.
Voice that doesn't sound like a robot.
Our specialists tune voice, prompts, and back-channeling per client — you don't touch a knob. Sub-second response, 800+ voices, custom clones. Inbound and outbound at concurrent scale.
White-label every layer.
Your domain. Your dashboard. Your client portal. Your billing. Even our specialists work under your brand — clients never see Callibre.
Multi-channel chat with shared context.
Same conversation across voice, SMS, WhatsApp, Instagram, Facebook, email, and live chat. Our team wires the routing per client — handoff happens without your customer re-explaining who they are.
Built for HighLevel
from day zero.
Snapshots install. Workflows trigger. Calendar, contacts, and opportunities sync. Our team owns the deployment per sub-account — your GHL-trained operators don't have to learn a parallel universe.
Enterprise agent infrastructure.
Handled end to end.
Build, test, deploy, and observe enterprise-grade AI agents from one platform — with our team working alongside yours at every step, under your brand.
Configure, test, launch.
One control panel for your entire agent — persona, knowledge base, tool integrations, guardrails, and escalation rules. No code required.
Visual conversation flows.
Map qualifying logic, branching paths, tool calls, and booking flows as connected nodes you can see, test, and edit.
Monitor every interaction.
Score conversations in real time and inspect every tool call, API payload, and decision your agent makes — before your client ever asks.
AI summaries, transcripts, and playback.
Every call gets an AI summary, full transcript, and cost breakdown. Filter, replay, and QA every conversation — down to cost per booked appointment.
Providers go down.
Your agents don't.
Callibre runs on our own in-house LLM and our own hosting — not on someone else's API. When OpenAI or Anthropic have an outage and half the AI industry goes dark, your agents keep talking like nothing happened.
Plugs into the
stack you already run.
Native integrations across telephony, LLMs, CRM, calendars, and support tooling. 50+ live today — and our open API handles whatever else your stack throws at it.
They sell software.

Enterprise-grade security,
built to pass their review.
Enterprise agents get enterprise scrutiny. The controls their security team asks about — spelled out, not buried in a badge wall. Encryption, access control, and signed agreements at every layer.
Encryption everywhere
AES-256 at rest, TLS 1.3 in transit. Keys managed and rotated — recordings and transcripts never stored in the clear.
Access control
Role-based permissions for every team, agent, and integration. SSO / SAML and SCIM provisioning available for enterprise.

Resilience by design
99.99% uptime SLA with multi-region failover and a priority call queue. Peak volume never drops a conversation.
Pure, itemized usage.
Zero markup games.
Build your exact cost per minute below — orchestration, model, telephony, and add-ons, every layer itemized. Platform pricing scales with you from first deployment to enterprise volume — talk to sales for a quote shaped to your rollout.
Frequently asked questions.
Everything a partner has asked us at least three times.
We join your Slack or WhatsApp. When something needs fixing, you message the same thread your team already works in and a Callibre engineer responds — 24/7, across timezones. No ticket portal, no queue number, no "have you tried the docs."
No. Our in-house prompt building team builds and tunes agents with you — from first script to ongoing optimization as your client's volume grows. You focus on selling and the client relationship; the ecosystem handles the craft.
Full conversations — from understanding intent and pulling information to completing tasks like booking appointments, creating tickets, qualifying leads, and updating your CRM. Agents escalate to humans only when configured to do so.
Voice, SMS, WhatsApp, Instagram, Facebook, email, and live chat — with the same conversation and context shared across all of them. Handoff between channels happens without your customer re-explaining who they are.
Real. Your domain, your dashboard, your client portal, your billing, your support tickets. Callibre is invisible at every layer your clients see — not a logo swap with someone else's URL underneath.
No. Sub-second response, 800+ voices, custom clones, and back-channeling tuned per client. Voice quality is the reason partners switch — and the reason their clients stay.
Usage is fully transparent — orchestration, model, and telephony itemized per minute with no markup, exactly as shown in the calculator. Platform pricing scales with the size of your deployment, from first client to enterprise volume. Talk to sales and we’ll shape a quote to your rollout.
Nothing your clients will notice — because your agents don’t run on them. Callibre runs its own in-house LLM on its own hosting. Third-party models like OpenAI and Anthropic are available as optional routing, but they’re never a dependency. On telephony we run Telnyx and Twilio with redundancy between them. When the AI industry has an outage day, Callibre agents stay on the phone.
Guardrails, grounded knowledge-base retrieval, and escalation rules are configured per agent. Every conversation is scored and inspectable — you can QA every tool call and decision the agent makes.
You keep your clients. Contact data, conversation logs, and workflows export cleanly. Your client relationships are yours — no hostage-data tactics.
Not hard — because you don't do it. Migration support is included: our team ports your prompts, knowledge bases, phone numbers, and workflows, rebuilds them on Callibre, and QA-tests everything before cutover. Most migrations run in parallel with your existing setup so there's zero downtime.
Your workspace is live on day one. Most partners deploy and bill their first client inside two weeks — our team builds alongside you from day one, drawing on agents we’ve already proven in your vertical.
Enterprise agents, without
the enterprise headcount.
Book a 30-minute call. We'll show you a working enterprise agent in your use case — and introduce you to the team that will be in your Slack the day you sign.
