VoiceB vs ElevenLabs, Bland, Retell, Decagon, and Salesforce Agentforce
By Alex Bisbe. January 9th, 2026.
AI voice is exploding. But most platforms are solving the wrong problem.
They optimize for voice quality, agent demos, or developer tooling. VoiceB is built for one thing only: turning inbound demand into revenue at scale.
This article explains where VoiceB fits — and why enterprises running real inbound sales choose it over alternatives like ElevenLabs, Bland, Retell, Decagon, and Salesforce AgentForce.
The Core Distinction: Voice vs Sales Autonomy
Most AI voice platforms answer one question:
“Can an AI talk like a human?”
VoiceB answers a different one:
“Can AI replace or augment inbound sales at scale, with measurable outcomes?”
That difference changes everything: product design, pricing, governance, and who actually gets value.
ElevenLabs: Best-in-Class Voice — Not a Sales System
ElevenLabs is a world-class text-to-speech engine. It excels at realism, emotion, and multilingual voice synthesis.
But ElevenLabs is not a sales platform:
No qualification logic
No intent classification
No routing or closing
No outcomes or revenue attribution
And that’s intentional — it’s infrastructure.
Important clarification: VoiceB uses ElevenLabs (and similar providers) for voice quality where appropriate.
We don’t compete with them. We build on top of them.
With VoiceB, enterprises get:
Best-in-class human voice
Plus autonomous qualification, selling, routing, and closing
Voice quality is table stakes. Sales autonomy is the differentiator.
Bland: Great Demos, Not Enterprise Sales Operations
Bland makes it easy to spin up AI callers quickly. It’s optimized for experimentation, demos, and lightweight use cases.
Where it breaks down for enterprise inbound sales:
No autonomy levels (everything is “agent-like”)
No deterministic outcomes
No audit-grade decision trails
Limited control over escalation, compliance, and scale
VoiceB is built for production sales environments:
Telco
Energy & utilities
Insurance
Banking
Automotive
These are not demo environments. They are revenue-critical systems.
Retell: Developer Flexibility Without a Sales Model
Retell provides developer-friendly building blocks to create voice agents. It’s flexible, but flexibility shifts the burden to the customer.
That means:
You design the sales logic
You define qualification
You maintain performance
You prove ROI
VoiceB ships with a sales operating model:
Qualification-first
Outcome-driven
Autonomous by default
Humans only where they add value
Enterprises don’t want to build sales logic from scratch. They want conversion lift.
Decagon: Support Automation, Not Revenue Generation
Decagon is focused on AI for customer support.
That’s a different problem:
Cost reduction
Ticket deflection
Case resolution
Inbound sales is the opposite:
High intent
Revenue risk
Conversion sensitivity
VoiceB is not a support tool adapted for sales. It’s a sales system designed for voice from day one.
Salesforce AgentForce: CRM Intelligence, Not Voice Autonomy
AgentForce sits inside the Salesforce ecosystem. It’s powerful for CRM workflows, copilots, and agent assistance.
But it’s not a voice-native sales engine:
Voice is an add-on, not the core
Latency, scale, and concurrency are constrained
Autonomy is limited by CRM-driven flows
VoiceB operates outside the CRM, at the moment of intent:
WebRTC
Click-to-call
Inbound phone
VoIP
And pushes structured outcomes back into Salesforce, HubSpot, or any CRM.
That separation is intentional — and critical for scale.
What VoiceB Actually Is
VoiceB is an Autonomous Sales Voice Agent (ASVA) platform.
One platform. Four autonomy levels:
L1 – Qualification: Filter noise, capture intent
L2 – Intelligent Routing: Send the right lead to the right closer
L3 – Assisted Autonomous Sales: AI sells, humans step in only when needed
L4 – Full Autonomous Sales: AI closes end-to-end (where compliant)
You don’t buy products. You choose how autonomous your inbound sales should be.
Pricing Reflects This Difference
Most platforms price:
Per minute
Per agent
Per seat
Per API call
VoiceB prices on outcomes:
Per qualified lead
Per AI-closed sale
Per transferred revenue opportunity
Because voice is not the value. Conversion is.
Best of Both Worlds
To be clear:
Yes, VoiceB sounds human
Yes, we use ElevenLabs, Bland, and other best-in-class voice providers
No, voice alone is not enough
With VoiceB, enterprises get:
Best-in-class voice quality
Plus autonomous sales intelligence
Plus enterprise governance
Plus measurable revenue impact
Voice is solved. Inbound sales is not.
That’s why VoiceB exists.
