Korea’s voice infrastructure company for AI calls
The phone is the oldest and most widely deployed voice interface. Voice AI is reopening it, but building a service on top takes numbers, lines, compliance and payments first. KAT lays that foundation so anyone building voice services in Korea can start on top of it.
Figures as of November 2026.
Brand architecture

Who it’s for
Order- and booking-based businesses, platform companies, ZeroCall users
The lower the layer, the closer it is to infrastructure we own. Whichever layer a problem starts in, one point of contact diagnoses and fixes it.
We find the problem in the moment a business misses a call, then pick the technology.
We don’t stop at answering. Bookings, payments and records get done.
We issue numbers and run our own switch, so call quality and outages are ours to own.
We compared approaches, not companies. KAT covers everything from the line to the payment, with one point of contact.
