Conversion Rates That Redefine Inbound Sales

by Alex Bisbe. August 26th, 2025

At VoiceB.ai, our mission is simple: help enterprises sell more without adding more agents. The way we do this is best explained in one metric — conversion rates.

AI Conversion Rates That Match Humans

In our first live campaigns, VoiceB’s AI agents are delivering conversion rates that match human performance:

• 10–15% sales closed by AI alone, fully unassisted.

• Example: In an energy campaign with a top Spanish utility, our AI closed 11.7% of all leads — directly in line with the human average of 10–15%.

This means AI is not a supporting tool. It is a real sales closer.

Smarter Funnel, Higher Overall Conversions

The strength of VoiceB lies in how it handles every single inbound call:

• ~50% filtered as invalid traffic (existing customers, hang-ups, fake numbers).

• 10–15% fully closed by the AI agent.

• 35–40% qualified as Talk To Agent, with summaries, objections, and intent captured for the human team.

This structure widens the funnel: Humans only spend time on leads with real intent, while AI handles filtering and closing. The result is more total sales from the same lead volume.

At VoiceB.ai, we don’t just promise results — we track and deliver real outcomes. Every call is logged with its status and conversion result, whether it’s Sold, Talk to Agent, or Not Interested. For example, in recent live campaigns you can see AI outcomes in action: one call marked Sold after 6 minutes, others flagged as Talk to Agent for human follow-up, and invalid leads instantly filtered out.

This level of transparency ensures that enterprises always know exactly how many sales the AI is closing and how many qualified opportunities are being handed over to the team.

Why Conversion Rates Matter

Traditional call centers face staffing bottlenecks. More calls mean more queues, missed opportunities, and frustrated customers. With AI:

• Every call is answered instantly — no missed opportunities.

• Invalid calls never drain human resources.

• Human agents get only the most promising leads, increasing their personal close rates.

The outcome: higher conversion, no extra headcount.

The Bottom Line

VoiceB.ai proves that AI can sell. Not only does it achieve human-level conversion rates, but it also reshapes the funnel to ensure every lead is maximized.

👉 With 10–15% direct AI conversion and 35–40% qualified handoffs, enterprises can achieve more sales with the same team size — a true breakthrough in inbound sales.
