Why the name Cayia?
Cayia means control with intelligence.
The name comes from the Spanish idea of “Cajero Automático y Inteligencia Artificial”: cashier tools, business tracking and AI guidance in one place.
Cajero + AI
Born from cashier automation, expanded into a control center for multi-work businesses.
