"In the past, developing data-driven insights or technical proposals for clients often required support from multiple teams. Today, with AI, I can analyze a client’s situation more quickly and design customized solutions independently."
Sumin Jo, a Business Analytics MBA (BA MBA) student, works as an account manager in Toss's Cross Domain Sales Team. In her role, she brings together various toss services—including payments, loans, advertising, and commerce—to deliver integrated solutions. "Rather than selling a single product, I communicate directly with decision makers and solve their business challenges by combining different toss services," she explained.
Reflecting on her MBA experience, Sumin shared: "The program helped me realize that AI is not a specialized technology reserved for experts—it can become an everyday work partner. Whether I am analyzing data, preparing reports, or organizing client information, AI significantly improves both speed and efficiency."
Although she does not consider herself a data analytics specialist, the BA MBA program showed Sumin how AI can simplify complex processes. "Through the coursework, I experienced firsthand how AI can make complicated data much easier to organize and understand,” she said. “At a company like toss, which operates multiple business units, this is especially valuable. As an account manager representing a wide range of businesses, I can train AI on relevant business information, retrieve the information when needed, and use it to develop tailored proposals for individual clients."
She added, "My role requires me to absorb large amounts of information quickly and communicate it in a way that clients can easily understand. The AI applications I learned through the program make that process faster and more sophisticated."
Looking ahead, Sumin believes AI will continue to expand the scope of individual capability. "The biggest change AI brings is the expansion of what a single person can accomplish," she noted. "In the past, data analysts, client solution specialists, and technical managers each contributed their expertise as part of a team. Today, AI is creating an environment where one person can perform aspects of all those roles." She believes this shift will be particularly impactful for sales professionals.
At the same time, Sumin stressed that human relationships will become even more important as AI capabilities advance. "As AI takes on more technical and analytical work, the most important capability for account managers will be developing a deep understanding of clients," she explained. "Our role is to understand clients’ challenges and goals, build trusted partnerships, and grow together with them."
Sumin concluded: "That is what lies at the heart of being an account manager. Rather than replacing people, AI allows us to focus more on the human side of the role. It creates an environment where we can become even better partners to our clients."
