AI Inside Sales Agent vs. human ISA: a practical comparison for brokerages
A human ISA costs ~$50k+ and handles one call at a time. An AI ISA answers every lead instantly, 24/7. Here is how to think about the trade-off.
The short answer
A human Inside Sales Agent (ISA) typically costs $50,000+ per year fully loaded, works one conversation at a time, needs months of training, and is offline nights and weekends. An AI ISA answers every lead in under 90 seconds, handles unlimited conversations in parallel, never churns, and works 24/7 — usually for a fraction of the cost. Most brokerages use AI to cover the speed-and-scale work and keep humans for showings, negotiation, and closing.
Where humans still win
Local nuance, emotional read, hard negotiation and trust at the closing table remain deeply human. The goal is not to replace agents — it is to stop wasting their time on leads that aren’t ready, and stop losing leads to slow follow-up.
Where AI wins
| Dimension | Human ISA | AI ISA (Livia) |
|---|---|---|
| First response time | Minutes to hours | < 90 seconds, always |
| Availability | Business hours | 24/7/365 |
| Concurrent leads | One at a time | Unlimited |
| Memory | Notes, if any | Every detail, forever |
| Ramp / training | ~3 months | Live in days |
| Cost | $50k+ / yr | From $500 / mo |
The honest framing
The question isn’t “human or AI”. It’s “how many of the leads you already pay for are dying in the gaps a human can’t cover?” For most brokerages that number is large — and it’s the cheapest growth available.
