Kim Seung-yeon transitions to a sole CEO system… 'All in' on retail business
Next Securities has officially started expanding its retail business with the transition to a sole CEO system led by Kim Seung-yeon.
Having led the growth of Toss Securities after experiences at Google and TikTok, CEO Kim is focusing all efforts on launching a mobile trading system (MTS) in the first half of next year.

Next Securities recently changed its leadership structure from a dual CEO system of Kim Seung-yeon and Lee Byeong-joo to a sole CEO system with Kim Seung-yeon. The company explained, "We naturally restructured our leadership to focus more on new business areas."
Born in 1980, CEO Kim has served as the Asia Marketing Head at Google, head of Southeast Asia Business Solutions at TikTok, and was appointed as the CEO of Toss Securities in 2023, overseeing the retail division. After being appointed CEO of Next Securities last year, he announced the company's entry into B2C and changed the company name from SI Securities to Next Securities.
AI, Global, Platform… Three Core Strategies
In his New Year's address this year, CEO Kim presented AI, global reach, and platform development as core objectives. He stated, "We will leverage AI technology to deliver personalized investment experiences and support data-driven decision-making platforms," adding, "We will enhance cross-border stock trading services and offer financial products that align with global trends."
He also mentioned, "We will establish a foothold in key markets like the United States and position ourselves as a financial company that meets global standards."

Next Securities is expanding its office in the Three IFC in Yeouido and has established a new platform development organization in preparation for the launch of the MTS in the first half of next year. The MTS the company is preparing is characterized by combining content platforms with securities trading functions, processing market information and public data in real-time, and providing personalized insights in intuitive short-form videos.
Fierce Market Competition… Differentiation is Key
Next Securities has declared the launch of an 'AI and content-based' MTS, but the market is already dominated by Toss Securities and Kakao Pay Securities.
In this competitive landscape, Next Securities aims to provide a differentiated customer experience by designing a platform where all processes, from information search to stock trading, are conducted within a single platform. Reports suggest that, rather than prioritizing global expansion plans, the company is preparing for a domestic market launch.
Meanwhile, Toss Securities is accelerating its global expansion.

Toss Securities’ subsidiary TSAF (TSA Financial) received approval from the Financial Industry Regulatory Authority (FINRA) in June and is officially registered as a broker-dealer in the U.S., planning to provide direct overseas stock brokerage services in the U.S. market.
