Outcomes

What you can expect

Real numbers we see when Voice AI Agent ships on top of an actual workflow. Specifics vary with starting baseline, data quality, and scope — but these are the ranges.

Response time

From minutes to seconds — at any hour, any volume.

Outcome 02

55-75%

Deflection rate

Tickets resolved without a human after 4-8 weeks of tuning.

Outcome 03

+8-15

CSAT lift

Net points, measured side-by-side against human-only baseline.

Sample use cases

What this looks like in practice

Three concrete scenarios where teams deploy Voice AI Agent today. Your engagement starts with one of these (or your own variant) and expands from there.

01

After-hours support without staffing

A 24/7 SaaS company routes all overnight tickets through the agent. ~70% resolved before morning, the remaining queue is triaged with full context so the day team starts where it matters.

02

Multilingual sales qualification

A remote-first e-commerce brand qualifies UK + various jurisdictions + Gulf leads in their preferred language, books a demo, and hands off only sales-ready conversations to the closer.

03

Refund + reorder self-service

A D2C retailer lets shoppers initiate refunds, change addresses, or reorder previous purchases through chat — agent enforces policy, escalates edge cases, posts updates to the order DB.

Typical engagement

From kickoff to live in 4-8 weeks

Most Voice AI Agent engagements follow this shape. We give you a firm quote after a 30-minute scoping call, and the price is fixed up-front so you can budget.
