Wrtn Technologies closed a 100 billion won Series C on Wednesday, equivalent to roughly $72.2 million, valuing the Seoul-based AI services company at more than 1 trillion won, or $722 million. The round pushes Wrtn's total capital raised to approximately 230 billion won, about $166 million.
New investors joining include Coreline Ventures and Eugene Asset Management. Existing backers Goodwater Capital and Korea Development Bank also participated. The company said it will deploy the capital toward international expansion and product development.
The commercial engine behind this round is OOC, Wrtn's North America-facing AI entertainment platform. OOC crossed 10 billion won, or $7.22 million, in monthly revenue within three months of its May 2026 launch. At that run rate, OOC alone approaches $86 million in annualized revenue.
Wrtn's domestic and Japanese products operate under the brand names Crack and Kyarapu. The platforms are interactive AI storytelling services: users build characters, shape narratives and steer plots in real time.
The company's full-year revenue target is aggressive. Wrtn expects 2026 revenue to exceed 200 billion won, roughly $144 million. That compares with 47.1 billion won, or about $34 million, last year. If achieved, that is more than a 4x increase in a single year.
At 200 billion won in revenue and a 1 trillion won valuation, Wrtn is trading at approximately 5 times forward revenue. For a private AI software company growing at 4x year-over-year, that multiple is conservative relative to U.S. SaaS peers at similar growth rates, which have historically commanded 10 to 20 times forward revenue in public markets. Wrtn has publicly flagged a potential IPO as early as 2028, providing roughly two years to sustain growth before testing that gap.
Revenue concentration is a material risk. OOC is a consumer entertainment product driven by subscription and in-app spending. Consumer AI entertainment lacks the recurring nature of enterprise contracts; churn is faster, and revenue can shift with platform trends or regulatory pressure. Wrtn acknowledged this in a separate disclosure: the company is tightening safeguards on its Crack platform for teenage users, including time-use restrictions, stronger parental consent requirements and lower caps on in-app spending. Those changes signal regulators or the company's own compliance team flagged the teen user segment as a liability.
The Korea Development Bank's participation as a continuing investor carries strategic weight. KDB is a state-owned policy bank. Its backing provides implicit government validation for Wrtn's overseas expansion and potentially smooths regulatory conversations as OOC scales in North America. Korean government institutions have backed domestic AI champions aggressively since 2024 as competition with Chinese and U.S. AI firms intensified.
Goodwater Capital, a U.S.-based consumer technology fund, has backed Wrtn through at least two rounds. Its continued participation alongside KDB and Eugene Asset Management reflects a split investor base: U.S. consumer tech money betting on the entertainment platform, Korean institutions treating it as a national tech asset.
Wrtn's path to a 2028 IPO hinges on sustaining OOC's North American momentum. The platform reached $7.22 million in monthly revenue in its first quarter. If growth decelerates to normal consumer-app patterns—roughly 10 to 15 percent month-over-month after launch enthusiasm fades—the company needs Kyarapu and domestic Crack revenue to fill the gap toward its $144 million annual target. Wrtn has not disclosed user count or paying subscriber figures, which would clarify whether OOC's early revenue reflects genuine retention or launch-quarter novelty spending.
