Toss is a South Korean financial technology platform that brings together banking, payments, investing, insurance, credit management, money transfers, and other financial services within a single digital ecosystem. Operated by Viva Republica, Toss began with a simple money-transfer service in 2015 and has since expanded into a broader financial super app, supported by businesses including Toss Bank, Toss Securities, Toss Payments, Toss Insurance, and Toss Place.

The platform allows users to connect and manage bank accounts, cards, loans, and insurance products, compare and apply for financial services, invest, make payments, and access a growing range of everyday services. Toss surpassed 30 million users in Korea in 2025 and has continued to broaden its platform beyond finance through products such as Mini Apps, while beginning its international expansion with the launch of Toss in Australia.
