Ten years ago, the idea of financial transactions without an account number was virtually unimaginable. People routinely paid remittance fees every time they sent money to another bank, and earning interest on savings accounts required waiting until maturity. Today, services like Toss have revolutionized this landscape. With just a phone number, users can make unlimited, fee-free remittances and start earning interest on savings instantly.
Lee Seung-gun, CEO of Toss, celebrated this transformation at the 10th anniversary of the Toss app launch. Held at Anderson in Seongsu-dong, Seoul, on February 26, Lee reflected on the app’s impact:
“The innovation created by Toss over the past decade has changed its own growth beyond its own growth and changed the market’s topography by attracting the participation of other industrial actors.”
From Humble Beginnings to Financial Revolution
Lee’s journey began after graduating from Seoul National University, where he dreamt of making the world better instead of becoming a dentist. His early ventures, such as the SNS Ulabla and the mobile voting app Davot, faced numerous challenges, but Lee persevered. Eventually, he pioneered simple remittance services using smartphones, despite initial skepticism from industry experts. Toss’s annual remittance volume skyrocketed from 80 billion in 2015 to 180 trillion in 2024, serving 12 million users.
Lee, emphasizing Toss’s evolution, argued that its simple remittance services have become the ‘New Normal’ in domestic financial markets. By offering frictionless transactions and passive income through interest, Toss has redefined what consumers expect from their financial services. Translated to a U.S audience, similar services could provide American consumers with an alternative to traditional banks and apps like PayPal and Venmo.

Innovation and Open Source Partnerships
Toss’s innovations extend beyond its core services. For example, the development of ‘1 won certification,’ which uses a one-won deposit and the resulting sequence of numbers or words for verification, was pioneered by Toss. This technology, patented and widely used by financial firms, has never been restricted by the company. When asked about large companies adopting Toss’s innovations, Lee showed a magnanimous attitude.
Lee Seung-gun emphasizes a vision of collaboration and open innovation. He stated:
“When you talk about innovation, it’s the key for Toss to give chances and opportunities to partners.”

Expanding Offline and Global Markets
Lee Seung-gun also showcased Toss’s venture into offline payment markets. The app introduced ‘Face Pay,’ allowing customers to pay using facial recognition, with over 100,000 merchants already equipped with terminals. This reflects the widespread acceptance and rapid adoption of biometric payment technologies, aligns with trends set by companies like Apple Pay and Amazon.
Toss plans international expansion with the goal of making its services accessible to a global audience. By 2024, their vision included further advancing not just domestically within South Korea but internationally through an arm of investments into international vendors. Localized challenges which will arise will require unique approaches to matters like region-specific regulations, currency issues, and marketplace integration, in regions apart from just South Korea. Strategic partnerships and tailored solutions, similar to how Paypal has expanded successfully worldwide, will they pursue to ensure seamless transitions. This expansion represents a pivotal milestone in Toss’s journey and mirrors the ambition of tech giants like WeChat Pay and Alipay, who dominate the mobile payment landscape in China and Southeast Asia, respectively.

Investing in the Next Generation of Innovators
Lee also revealed Toss’s commitment to supporting emerging startups with an investment of Won 1 trillion over the next five years. As anticipated surplus profits materialize, the core team aims to foster a supportive ecosystem for innovators, echoing the ethos of Silicon Valley’s venture capital culture. Adopting a Toss SDK Programming Toolkits Initiative,
the company offers a collaborative foundation. Tech giants like Google and Apple, who have achieved similar as well similar paths over the years, show us, similar foundations can indeed facilitate interdependence and strategic collaboration.
Lee concluded with an optimistic outlook on the future, calling the 10th anniversary a starting point of the next 100 years, expressing his ambition:
“I have nothing to say at the stage now.”
