Viva Republica, the operator of Toss, said on Monday its 2025 consolidated revenue totalled 2.7 trillion won. It was up 38 percent from a year earlier.

A filing on Monday showed Toss posted 2025 consolidated net profit of 201.8 billion won, up 846.7 percent from 21.3 billion won a year earlier. Operating profit came to 336.0 billion won, up 270.3 percent.

Toss cited stronger competitiveness in its platform business as the driver of the growth.

It said an expansion of customer participation services, together with stronger competitiveness in affiliate services, improved both new customer inflows and usage activity within the Toss app.

It said ad revenue rose as the efficiency of big data-based personalised advertising improved. It also said the volume of simple payments transactions increased, helped by an expansion of payment merchants and growth in in-app commerce.

It said usage frequency and conversion rates rose across advertising, payments and finance, supported by more than 30 million subscribers as of the end of last year, and that its monetisation structure also strengthened further.

A Toss official said, "2025 was the year Toss confirmed revenue growth based on a solid customer base and service competitiveness." The official said expanded use across services such as advertising, payments and finance, and synergy effects within the platform, translated into actual revenue.
