- Livetoon
Led · Seed · Jun 2024
Livetoon builds a proprietary speech-to-speech and text-to-speech (STS/TTS) engine optimized for Japanese, coupled with a 3D interface that enables lifelike conversations with AI characters. Its core offering includes the consumer-facing conversation app "kaiwa" and bespoke solutions for IP holders seeking to extend character engagement. By merging well-known Japanese characters with natural AI dialogue, the startup aims to create always-on "official conversation experiences" that deepen fan interaction and open new monetization channels. The company is enhancing its voice platform, adding richer conversational functions, and expanding the roster of IP partnerships. Future plans call for global distribution of Japan-origin intellectual property, turning beloved characters into interactive assets for audiences worldwide. Financially, Livetoon has raised ¥75 million in equity to date to accelerate product development and team expansion. The firm was founded in March 2024.

Universe Production uses digital channels such as social media and the metaverse to promote local culture, history, and specialties as entertainment and regional marketing. The firm is developing original content (anime, music), an original platform for shared VTuber services, metaverse events, virtual product fairs, and virtual tourism experiences. It is also exploring overseas collaborations and AI-powered multilingual content to increase global access. The company recently completed a seed funding round reported at ¥20 million to support these expansion plans.
