Why businesses choose Cason AI over Human ISA Teams
An internal sales agent (ISA) or business development representative (BDR) is the traditional solution for lead follow-up. Human ISAs are expensive, limited to business hours, inconsistent in quality, and can only handle one call at a time. As lead volumes grow, the cost scales linearly — and performance rarely improves.

What they offer
An internal sales agent (ISA) or business development representative (BDR) is the traditional solution for lead follow-up. Human ISAs are expensive, limited to business hours, inconsistent in quality, and can only handle one call at a time. As lead volumes grow, the cost scales linearly — and performance rarely improves.
A human ISA costs £2,500–£5,000 per month per head — before management, training, benefits, and ramp time.
This is why businesses switching from Human ISA Teams consistently report better results with Cason AI.
When does it matter most?
In sales, the window between a lead arriving and intent fading is measured in minutes — not hours. The platform you use determines whether you win or lose that race.
The difference is not subtle.
A human ISA costs £2,500–£5,000 per month per head — before management, training, benefits, and ramp time. Cason AI's usage cost is €0.30/min. The economics are not close.
Human ISAs work 9–6. Leads arrive 24 hours a day. The mismatch is structural — Cason AI fixes it permanently by operating around the clock with no shift changes.
The best human ISAs are inconsistent. The worst are actively damaging your brand. Cason AI applies the same qualification criteria, tone, and process to every single call.
