Toss Bank is consolidating its data capabilities, creating a dedicated data analysis team and hiring an external expert to enhance its data-driven decision-making processes.


According to the financial sector on August 9, Toss Bank has recently established a dedicated data analysis organization within its data division. The new team will be led by Lee Jae-heon, who previously worked at Kakao.


Lee has extensive experience in data analysis, having worked at financial and fintech companies such as Samsung Card, K Bank, KB Kookmin Card, and Kakao Pay. He served as the head of the data analysis team at Kakao Pay and later managed corporate initiatives and new business at Kakao. He is recognized as an expert in building data-driven decision-making systems across various sectors, including finance, fintech, and big tech.


At Toss Bank, Lee will lead not only the new team but also the data analysis personnel scattered across various departments, aiming to enhance the bank's overall data analysis capabilities.


As an internet-only bank, Toss Bank relies heavily on data analysis for personalized financial services, credit assessments, risk management, and marketing efficiency, all of which impact the bank's profitability and stability. By analyzing customer financial transactions and service usage patterns, the bank can offer tailored products and utilize data for loan assessments and risk management.


Toss Bank is also strengthening its leadership in technology. It has appointed Song Tae-hwa, who previously led the server platform organization, as the Chief Operating Officer and the head of server development technology. This move aims to drive key initiatives such as technology internalization and system advancement at the executive level.


The bank is actively seeking talent as well. Toss Bank is conducting an internship program linked to server developer recruitment until August 17, planning to select a double-digit number of interns. These interns will participate in product, service, and platform development for six months, with opportunities for outstanding candidates to transition to full-time positions. The program aims to provide hands-on experience in core banking areas such as lending, deposits, cards, and asset management, ensuring that the bank secures talent with a solid understanding of the financial domain and development capabilities.


A Toss Bank representative stated, "We plan to enhance our overall data utilization capabilities and technological foundation by strengthening leadership in data analysis and server development. Based on this, we aim to improve our service competitiveness and reliability, providing customers with more convenient and trustworthy financial services."
