The Autonomous Inbound Sales Layer

into revenue. Autonomously.

Not just conversations. Complete sales execution across your systems.
Built for enterprises handling 1,000+ inbound leads per month.

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."

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
