AI ISA vs Human ISA.
The structural cost gap.

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.

Solaia vs Human ISA — your questions answered.
Is an AI ISA better than a human ISA?+
For first-contact lead qualification, an AI ISA wins on cost, coverage, and consistency: it works 24/7, handles unlimited conversations in parallel, responds in under 2 minutes, and speaks 30+ languages. Humans still win on complex negotiation and relationship building, so the best model is AI for first contact and humans for high-value handoffs.
How much does a human ISA really cost?+
A skilled human ISA costs roughly $7,500–$9,500/month fully loaded — salary plus benefits, tools, and management overhead — for about 8 hours of coverage a day in one or two languages. Solaia's managed AI service runs $1,990–$4,500/month for 24/7 coverage across 30+ languages.
How is Solaia different from hiring a human ISA?+
Solaia is a managed AI service, not a hire. There's no recruiting, training, turnover, or sick days. It responds in under 2 minutes around the clock, handles many conversations at once, qualifies on budget, timeline, and financing, and books viewings directly — then escalates high-value, relationship-driven moments to your human agents.
Does an AI ISA replace my agents?+
No. Solaia replaces the qualification and first-response work — the repetitive, time-sensitive layer — not the relationship work. Your agents focus on viewings, negotiations, and closing while Solaia ensures no inquiry goes unanswered, including the ~78% that arrive outside working hours.
What is the cost of Solaia versus a human ISA?+
One human ISA's fully loaded cost typically covers 2-3 Solaia retainers, and Solaia adds 24/7, multilingual, parallel coverage on top. Solaia uses a managed retainer plus per-viewing performance fees; use the Solaia ROI calculator to compare against your current ISA spend.
