AI service platform company Wrtn Technologies has secured 100 billion won in Series C funding, elevating its valuation to over 1 trillion won, marking its emergence as a unicorn within just five years of its establishment. This growth reflects its success as a leading AI company in South Korea and its competitive service offerings in global markets, including Japan and the United States.
On August 26, Wrtn announced the completion of its 100 billion won Series C funding round. New investors Coreline Ventures and Eugene Asset Management participated, alongside existing investors such as Goodwater Capital, Antler Global, Woori Venture Partners, Suigenesis Partners, the Korea Development Bank, and Capstone Partners. With this investment, the total amount raised by Wrtn has reached approximately 230 billion won.
This funding round has recognized Wrtn's valuation at 1 trillion won. Notably, the company has increased its value by simultaneously growing its user base and revenue through services directly utilized by consumers.
Founded in April 2021, Wrtn began its journey by securing seed funding from Mashup Ventures in June of the same year. It followed up with a pre-Series A investment of 3.8 billion won in November 2022, a Series A investment of 15 billion won in June 2023, a pre-Series B investment of 29 billion won in June 2024, and a Series B investment of 83 billion won in March 2025.
As of March 2025, Wrtn had accumulated approximately 130 billion won in investments, becoming the first domestic AI service platform startup to surpass 100 billion won in total funding. With the addition of the Series C round, the total investment has now increased to about 230 billion won.
As investment has grown, so has the number of service users. Wrtn launched its AI service 'Wrtn' in 2022, which utilizes generative AI to assist users with inquiries, writing, searching, and various tasks. The company has since expanded its offerings with 'Crack,' an AI character that allows users to engage in conversations and enjoy content.
Recently, Wrtn has also achieved success in global markets. The AI entertainment content platform 'OOC,' launched in North America in May, surpassed 10 billion won in monthly sales within just three months of its release. Based on this growth in global business, Wrtn anticipates that its total revenue will exceed 200 billion won this year.
Wrtn is also expanding its business scope into AI entertainment and content. With Crack as its centerpiece, the company is targeting markets in Japan and North America, broadening its reach as a global consumer AI platform. Additionally, it is increasing its engagement with the gaming and content industries. Wrtn plans to participate as a main sponsor at G-Star 2026, set to take place in November at BEXCO in Busan, to promote its AI entertainment platform to the gaming audience.
Osuke Honda, co-founder and partner at Coreline Ventures, stated, “Wrtn is becoming a phenomenon in the global market. The platform is leading the entire consumer AI movement, which is fundamentally transforming how AI interacts with human creativity, communication, and online engagement.”
Wrtn CEO Lee Se-young remarked, “The Wrtn team started with the belief that a world-class consumer AI company could emerge from Korea. Although we began as a small startup, we have been able to continue innovating as a global leader in AI, thanks to the support of our dedicated colleagues and investors who shared that belief.”
