Letsvan is a Chinese designer toy and IP incubation company founded in 2020. The company focuses on original character development and collectible toy sales. Its breakout IP is WAKUKU, created in 2024 — a character depicted with round cheeks, oversized eyes, messy hair, small fangs, and a distinctive set of straight eyebrows, embodying a spirit of freedom and mischief. WAKUKU gained rapid market traction internationally. In 2025, Nasdaq-listed QuantaSing Group acquired a majority stake in Letsvan, significantly expanding its resources and distribution reach, while a joint venture with Yuehua Entertainment further accelerated WAKUKU's brand development.
