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.

Common questions
An ISA (Inside Sales Agent) or BDR (Business Development Representative) is a dedicated team member responsible for following up with inbound leads, qualifying prospects, and booking appointments for senior sales staff. They are the first human touch in the sales process — the role Cason AI automates entirely.
For the specific task of first-touch lead follow-up and qualification, yes. Cason AI responds faster, works longer hours, handles more calls simultaneously, and applies consistent qualification criteria every time. The output — qualified leads with booked appointments — is the same. The cost and reliability are dramatically better.
A dedicated human ISA costs £2,500–£5,000 per month in salary alone, before benefits, management overhead, training, and ramp time. Cason AI's usage is billed at €0.30/min — for a business receiving 500 leads per month with 2-minute average calls and 70% pickup rate, that is approximately €210/month in usage costs, plus the annual license fee agreed at consultation.
