KTis was established in 2001 when KT spun off its 114 directory assistance business, and it listed on the KOSPI in 2010 as KT group's customer service subsidiary.
Its operations consist of running the KT customer center for the parent's product and service inquiries, operating outsourced contact centers (BPO) for external clients across finance, healthcare, public sector and retail, plus a retail distribution business and the 114 directory assistance service.
Based on the most recent disclosed breakdown, the KT customer center accounts for 44.6% of revenue, general (third-party) contact center operations 32.4%, the retail business 18.7%, while directory assistance has fallen to just 3.1%.
KTis operates contact centers for more than 120 institutions and is combining its operational experience with KT group's AI technology to pursue a transition toward becoming an 'AX Contact Platform Company.' Notably, it has embedded KT's cloud-based AICC solution, the A'Cen Cloud consulting application, into its own contact center operations, commercializing AI call summarization and chatbot/voicebot features.
Its former digital advertising business (including elevator advertising) was spun off and sold during 2025 and is no longer part of current operations.
On the competitive front, Ubase Group, the country's largest BPO operator, along with fellow KT group affiliate KTcs and Hyosung ITX, compete in the domestic contact center and AICC market.
The KT customer center business provides a stable revenue base rooted in a captive contract structure with the parent, but this also comes with a structurally high degree of dependence on KT.
