Comparison

AI ISA vs Human ISA.
The structural cost gap.

A skilled human ISA used to be the gold standard for real estate lead qualification. The economics are breaking down — here's the full breakdown vs. Solaia's managed AI.

Response time

Minutes to hours

Under 2 minutes, guaranteed

Onboarding time

2-4 weeks (training)

48-72 hours (configuration)

Turnover risk

High — average tenure 8-14 months

None

Consistency

Variable (mood, fatigue, day-of-week)

100% — every conversation, every time

Where humans still win

Complex negotiations, deep relationship building, market expertise

Replaces qualification — not relationship work

After-hours coverage (78% of inquiries)

Lost — leads go to voicemail

Captured — instant response, viewing booked by morning

The math nobody talks about

The cost of one human ISA covers 2-3 Solaia retainers. And Solaia covers the 78% of inquiries that arrive outside the human's working hours. The right model in 2026 isn't AI vs human — it's AI for first contact + human for high-value handoffs. Solaia is built for that hybrid.
