Five9vs Callvu

Five9 is a cloud contact center platform with AI agents for self-service and Five9 Orchestrate, which runs AI actions and workflows in connected systems. Callvu is not a contact center. It is the Completion and Compliance Layer that runs the regulated work a conversation starts, through to the system of record: documents, decisions and write-back, with every regulation and company policy enforced on every step by a deterministic orchestrator. Callvu works alongside Five9.

The fair version

What Five9 is built for.Sourced from their own pages.

Five9 is a public cloud contact center company [1] whose platform includes the contact center, omni-channel engagement and embedded AI [1]. Its AI Agents and Voice AI Agents handle self-service, with tool calling to authenticate customers and update records added in June 2026 [7], and its flow-based Intelligent Virtual Agent remains available for predictable cases [2]. Five9 Orchestrate runs multi-step workflows across CRM, billing and case systems, with rules-based routing, permissioned AI actions that update systems of record, and pauses for a person to review or approve [3]. AI Trust and Governance adds guardrails, redaction and hallucination monitoring [4], with controls and audit trails for how AI agents operate [3]. Its financial services pages describe dispute cases that pause for an authorised reviewer above a configured limit and record the systems checked, rules applied and approvals given, and agents that capture claim photos and match them to the policy record [5]. Visual IVR shows menus and forms on smartphones [6].

When to choose which

Two different jobs.Pick the one you need.

When to choose Five9

Choose Five9 when the need is a cloud contact center [1]: routing, voice and digital channels, AI and virtual agents for self-service [2], and workforce engagement, with integrations to the main CRM and case systems [3].

When to choose Callvu

Choose Callvu when the regulated work a Five9 conversation starts must finish in the system of record. Callvu is not a contact center; it works alongside one. Five9 routes the work, updates systems of record and can pause a run for approval [3]; Callvu adds what its documentation does not describe: prefill from the core, documents requested, chased and verified from customers and third parties on a clock, and every control enforced on every step. Callvu orchestrates the work, routes it by work type, skill and due date, applies rules and policies and manages every decision, with five moves: it prefills from the core, classifies each request the moment it lands, chases and verifies documents from customers and third parties on a clock, routes decisions to the Decision Desk, and writes the result back to the system of record by API.

Guardrails are not runtime enforcement. Five9's AI agents take permissioned actions within guardrails [3][4], and missed disclosures are scored after the interaction [5]. Even with guardrails, an AI that runs a step can write wrong data to the system of record, take a path that is not in the workflow, or act compliantly most of the time rather than every time. Callvu does not let AI run the process. A deterministic orchestrator executes every step of a defined workflow and enforces every control before the step runs; AI only starts a process or evaluates it. Every run is recorded in a Decision Trace and an Audit Trace.

Side by side

The verifiable facts.Nothing else.

Every cell about Five9 is sourced from its own public pages. Runtime enforcement and the handoff lead the table because they are where the two differ most.

Runtime compliance enforcementYes. A deterministic orchestrator runs every step; AI never runs the process. Every regulation and company policy is enforced on every step while the work runs, whether a person or an AI started it; a step that fails a control does not run. A Decision Trace and an Audit Trace for every runNot a platform capability. Five9 documents deterministic flow-based virtual agents for fixed paths, approval thresholds in workflows, and guardrails and audit trails for AI agents; interactions are scored for missed disclosures after the fact. Its AI agents decide how to act, and no layer enforces every regulation and company policy on every step [3]
Front-to-back-office handoffYes, end to end: prefill from the core, classify the work, chase and verify documents on a clock, route decisions to the Decision Desk and write back to the system of recordPartial. Five9 Orchestrate runs scoped, permissioned actions that update systems of record across CRM, billing and case systems, and pauses a workflow for a person to review or approve. Prefill from the core, requesting, chasing and verifying documents from customers and third parties on a clock, and enforcement on every step are not documented [3]
AI guardrails vs deterministic executionDeterministic execution, not guardrails: AI never runs the process. A deterministic orchestrator executes every step and enforces every control before it runs, so nothing unchecked reaches the system of record and no step outside the workflow can happenAI agents take permissioned actions in systems of record within guardrails, redaction and monitoring [3]
Requesting and verifying documentsRequests, chases and verifies documents from customers and third parties on a clockAI agents capture claim photos and match the information to the policy record at first notice of loss; requesting, chasing and verifying documents from customers and third parties is not described [5]
Contact centerNo. Callvu works alongside the contact center and takes the work from the conversationYes: routing, voice, digital channels, Visual IVR and workforce engagement [6]

Using both together

Keep what works.Add the layer that finishes it.

Five9 stays the contact center. A Five9 call, AI agent or workflow starts a Callvu process; Callvu collects and verifies documents, sends exceptions to the Decision Desk, writes back to the system of record and returns the result and the Audit Trace to Five9 by API. Callvu can also run the whole process on its own, on web, mobile and Visual IVR.

FAQ

The questions buyers ask.Answered plainly.

Does Five9 enforce compliance at runtime?
Five9 offers deterministic flow-based virtual agents for predictable cases, approval thresholds in workflows, guardrails on AI agents and after-the-fact scoring for missed disclosures. Those are controls on individual steps and on AI. They are not a policy layer that enforces every regulation and company policy on every step of the process. Callvu does, with a deterministic orchestrator and AI never running the process.
Is Callvu a contact center platform?
No. Callvu is not a contact center. It works alongside Five9 and runs the regulated work a conversation starts through to the system of record.
Can Callvu work with Five9?
Yes. A Five9 call, an AI agent or a workflow can start a Callvu process. Callvu runs it to completion, with documents, decisions and write-back, and returns the result and the Audit Trace by API.
Is it safe to let a contact center AI agent update the system of record?
Even with guardrails, an AI that performs a step can write wrong data to the system of record, take a path outside the workflow, or act compliantly most of the time rather than every time. With Callvu, the AI captures the request and a deterministic orchestrator executes it, enforcing every control first.
How fast can Callvu go live alongside a contact center?
Callvu builds the process for you and goes live in a few weeks. PSEG Long Island went live in 4 weeks, integrated with NICE CXone, and AT&T launched 12 workflows in 6 weeks.
