# Contact Center Software (CCaaS) - Zendesk, TCN, Puzzel, Regal, UJET, Bright Pattern

> A field guide to the contact-center software market as it is rebuilt around AI. Six platforms - the ticketing giant Zendesk, the veteran outbound specialist TCN, the Nordic omnichannel player Puzzel, the AI-native newcomer Regal, the mobile-first UJET, and the omnichannel builder Bright Pattern - each represent a different theory of what a call center becomes when the software can talk back. This story maps who they are, what you can actually do with them, and where the human agent fits once the AI picks up.

## Achievements

- Zendesk holds a dominant share of the IVR/customer-service software market, cited around 88% in some category trackers.
- TCN has operated cloud call-center technology continuously since 1999, one of the longest track records in the category.

- Regal has raised more than $80M total, including a $40M round in 2024 to scale enterprise AI phone agents.
- UJET pioneered a mobile-first, smartphone-native model for support, integrating device features like camera and biometrics into the call.
