What Scatter Lab does
Scatter Lab is a Seoul-based AI entertainment company that operates Zeta (제타), an AI-native entertainment platform launched in April 2024 where users become protagonists and co-create real-time narratives with AI characters. The platform is powered by Spotwrite-1, a proprietary large language model the company developed and self-hosts, optimized for entertainment and engagement rather than factual accuracy; the model treats imagination, unpredictable plot twists, and even hallucinations as features rather than errors. Scatter Lab vertically integrates data collection, model training, GPU serving infrastructure (more than 100 GPUs), and app design to balance 'fun performance' with cost efficiency. Zeta competes against YouTube, Netflix, Roblox, and Naver Webtoon as a third-generation entertainment paradigm rather than against other AI chatbots.
The company monetizes Zeta through a YouTube Premium-style freemium model: free users see mid-roll advertisements, while paying subscribers upgrade to the ad-free zeta Pro tier. Through November 2025, Zeta generated 22.9 billion KRW (~$15.6M) in revenue with 2.6 billion KRW in operating profit, marking six consecutive months of profitability since Q4 2024. Engagement metrics are category-defining: 2 hours 40 minutes average daily usage globally, rising to 3 hours 40 minutes for Japanese users (surpassing Netflix Japan). As of February 2026, Zeta reported 6.15 million cumulative subscribers, 1.2 million WAU, and 900K DAU, with over 90% of MAU in their teens and 20s.
Zeta launched in Korea (April 2024), expanded to Japan where it ranks #1 in AI entertainment apps (with Japan contributing the majority of the 60%+ overseas revenue share), and entered the US via closed beta in January 2026. Cumulative funding of 41 billion KRW (~$30M) has been raised from strategic investors SK Telecom, SoftBank, NCSoft, and Krafton. Scatter Lab's earlier product, Iruda (이루다), was a conversational AI chatbot that interacted with over 2 million users and generated more than 1 billion conversations, establishing the technical foundation for Spotwrite-1 and Zeta's emotional AI capabilities.
