Agent Studio
Ask anything about your campaigns, agents, and calls
Got it — we'll set this up cleanly.
First step: which campaign should this agent belong to?
If this is a new one, I suggest a compliant name like: "Northwind UK Sales" (max 3 words, clean, no symbols)
Do you want me to:
- Use an existing campaign (tell me which one), or
- Create a new one with that name?
Great — I'll prepare the campaign creation.
Here's what I'm about to create:
- Name: Northwind UK Sales
- Type: LEAD_GEN (default — we can adjust if this is more of a full sales or digital journey flow)
- Timezone: Europe/London (default)
- Start date: 2026-08-25
Before I proceed, quick check:
✅ Do you confirm creating this campaign with these details?
Also — is this agent meant to qualify leads or actually sell/convert users? That second part matters because it defines how I build the agent (Lead Qualification vs Autonomous Sales).
✅ Campaign Northwind UK Sales created.
Now reading https://www.northwindfinance.com/en/ to build the agent: extracting products, tone of voice, and FAQs. I'll draft the agent prompt in UK English and show it to you for review before going live.

Testimonial
"For complex journeys in Telco, Utilities, and Insurance, VoiceB's autonomous agents guide users end-to-end — completing forms through live conversation, increasing digital sales, and reducing operational costs. It's the backbone of how we deliver smarter, faster, and more profitable inbound sales."
Victor M. Sanchez
Managing Director at GAIN, a t2ó ONE company
Case Study
"Our objective with VoiceB is clear: no customer should wait in a queue, and our agents should only speak with people who are reachable and genuinely ready to buy. VoiceB's autonomous agents attend every inbound call instantly, qualify the demand in seconds, and transfer only sales-ready customers to our team. For ready to buy customers, they close the sale fully autonomously, without needing a human agent at all. The result is a better experience for the customer and a much more efficient use of our sales capacity."
Oriol Pou
Head of Direct Sales at Holaluz
Case Study

01 — Execution
AI that doesn't just talk. It executes.
Most AI agents stop at the conversation — they answer, qualify, and hand off. VoiceB keeps going. Our agents operate your systems in real time to do the work that actually moves a customer from intent to revenue.

05 — Autonomy
One Platform. Four Levels of Sales Autonomy.
These are not stages of a call — they are degrees of delegation. You choose how far the agent goes, per use case, and move up when the results earn it.

Qualify and structure inbound demand, with every conversation resolved into clean, typed data.
→ Demand resolved into data
02
L2 — Decide
Route, prioritise and determine the next-best action against your own commercial rules.
→ Your rules, applied in real time

L3 — Execute
Operate enterprise systems and complete the sales tasks a human agent would perform.
→ Work done inside your stack

L4 — Close
Run the complete transaction autonomously, end to end.
→ Revenue without agents

Beyond AI voice
The conversation is the easy part. What happens during and after it is where revenue is won or lost.

Optimise acquisition for sales, not leads

09 — Platform
The platform behind the agents
Voice quality is a commodity.
Proof is not.
The hard problem is knowing — deterministically and auditably — what every call was worth, and feeding that signal back into the systems that generate your demand.
The Outcome Engine — refined on hundreds of thousands of labeled production calls across telecom, energy, insurance and logistics.
Close the Loop With Your Ad Platforms
Every call becomes an auditable outcome — and every confirmed sale becomes a conversion signal. VoiceB sends Outcome Engine data back to Meta (Conversions API), Google Ads (offline conversion uploads), LinkedIn, TikTok and Microsoft Ads, so your campaigns optimize toward closed revenue instead of form fills.
Result: −37% cost per acquisition over 12 months at Primagas.
VoiceB never touches your budgets or keywords — it supplies the sale-level signal your campaigns are missing.
