Toss

Overview

Toss is a fintech super app founded in Seoul, South Korea in 2014 by Viva Republica. With over 28 million users covering more than half the South Korean population, it is one of Korea's most influential digital financial services entry points. Toss started with minimal money transfers and expanded into Toss Pay payments, securities trading, internet banking, insurance and credit management.

Toss's core value is "one app for all financial needs": personal transfers, bill payments, Toss Pay online and offline payments, Toss Securities trading, Toss Bank internet banking accounts and Toss Score credit assessment, all in one place. For merchants serving Korean consumers, Toss Pay offers online checkout and QR collection — an important channel into Korea's digital payment market.
