Viva Republica, the operator of the financial super app “Toss,” announced that it had been selected as an official partner for Harvard Business School’s (HBS) global immersion program, FIELD Global Capstone. As part of the program, a team of HBS MBA students visited the Toss headquarters in Yeoksam, Seoul, from May 12 to 19 to work on a real-world, hands-on research project.
The project focused on mobile usability among millennial and senior users. Over the course of two months, the students engaged in preliminary meetings with the Toss team to develop initial hypotheses and conduct early-stage user research. They refined their hypotheses based on interviews with users in the United States, and upon arriving in Seoul, expanded their insights through user testing with actual Toss customers and street interviews with local residents.
The students also deepened their understanding of Toss’s service design philosophy and business context through working sessions with product owners, UX designers, and strategy leads—particularly those involved in senior-targeted features. Drawing from global case studies of super apps such as Alipay, Nubank, and Revolut, the students proposed localized ideas that could be relevant for Toss and shared their final recommendations in a closing presentation.
“We are pleased to have worked with Harvard Business School to support students in gaining real-world insights into corporate environments,” a Toss spokesperson said. “We hope this experience gave them a kind of learning that can only be found on the ground.”
The FIELD Global Capstone is a required HBS course designed to strengthen students’ practical skills and teamwork in diverse business environments. Toss was one of the selected partner companies across 14 cities globally, among more than 900 MBA students participating in the project.
