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.
