**Wrtn Technologies raised $72.2 million in a Series C round at a valuation between $722 million and $870 million**, announced on August 25, 2026 and led by **Coreline Ventures** and **Eugene Asset Management**. It's the first Korean AI service startup to cross a 1 trillion won valuation.

Here's the full breakdown of the raise, the backers, and why it matters for Korea's AI industry.

## What is Wrtn Technologies?

Wrtn Technologies builds an **AI aggregation platform** that combines multiple large language models — including GPT-4, Claude and Gemini — into consumer-friendly interfaces. Its two primary products are **OOC**, an interactive storytelling anime platform, and **Crack**, an AI character chat app focused on the Korean market. Founded in **2021** by **Lee Se-young, Lee Dong-jae, Youngjoon Yoo and Sungwon Jae**, Wrtn built its business on packaging other companies' models rather than training its own foundation model.

## The raise: $72.2M Series C

The headline numbers:

- **Amount:** $72.2 million
- **Round:** Series C
- **Valuation:** $722 million to $870 million (roughly 1 trillion won)
- **Announced:** August 25, 2026
- **Lead investors:** Coreline Ventures, Eugene Asset Management

Wrtn's path here included a **seed round in November 2022**, a **₩25 billion ($18.3 million) pre-Series B** in June 2024, and a **₩108 billion ($73.5 million) Series B** in March 2025. Crossing the 1 trillion won mark with this Series C makes Wrtn the **first Korean AI service startup** to reach that milestone.

## Who invested in Wrtn Technologies?

The round was led by **Coreline Ventures** and **Eugene Asset Management**. Additional participants included:

- **Goodwater Capital**
- **Antler Global**
- **Korea Development Bank**

## What Wrtn Technologies will do with the money

Wrtn said the funding will support **international expansion across East Asia**, GPU infrastructure and compute scaling, hiring specialized NLP engineering talent, multi-modal application development, and building safety guardrails for teenage users.

## Why it matters

1. **It's a milestone for Korea's AI ecosystem.** Being the first Korean AI service startup to top a 1 trillion won valuation validates that consumer AI businesses built outside the US and China can still reach unicorn-plus scale — a trend also visible across the [biggest AI funding rounds of 2026](/blog/biggest-ai-funding-rounds-2026).
2. **The aggregation model is proving out commercially.** Wrtn's OOC platform generated roughly ₩10 billion ($7.2 million) in monthly revenue within three months of its North American launch, suggesting that packaging existing LLMs into character-driven consumer products can compete with proprietary model builders, a pattern also seen at [June AI](/blog/june-ai-funding).
3. **Consumer AI entertainment is showing real growth.** Wrtn is projecting revenue to roughly quadruple year over year, from ₩47.1 billion in 2025 to over ₩200 billion in 2026, adding to the broader momentum behind [AI agents funding in 2026](/blog/ai-agents-funding-2026).
