About the founders/CEO:
Seung-Gun Lee is the founder and CEO of VivaRepublica, the company that launched the app called "Toss". A former dentist, he founded the company in 2013 because he was frustrated with how archaic web and mobile banking was in Korea and decided to change it himself.
He teamed up with Jooyang Jan, who is now the COO, and Hyungseok Lee, who is now the CTO; they both founded Tic Toc, a 10 million-user messaging app for Korea. The team is also formed by Younje Cho, the CFO, who is a former lead strategy consultant, and Youngseok Shin, who used to be part of the security team at the Blue House (Korea's White House) and who is now the head of security.
