4Utech (世优科技), registered as Shiyou (Beijing) Technology Co., Ltd. (世优（北京）科技股份有限公司) (formerly 世优（北京）科技有限公司), is a Beijing digital-human company founded in 2015. It began with real-time motion capture, facial capture and rendering to produce virtual hosts and virtual content, and grew into a full-stack supplier of 2D, 2.5D and 3D digital humans for tourism, broadcasting, finance, education, exhibitions and livestreaming.

Its investors came with the virtual-human boom. In January 2022 it raised an A+ round in the tens of millions of yuan, and in August 2022 a second A+ tranche of over ¥100 million from the listed companies Tiandi Online (天地在线) and Beijing Jetsen Technology (捷成股份) (Securities Times). Its production tools include a “Digital Human Factory” (数字人工厂) for rapid 3D avatar customisation and a virtual studio for XR livestreams and online events.

Its flagship product is BOTA (世优波塔), an interactive AI digital-human agent combining a custom avatar, large-model dialogue and multimodal interaction. It runs on large screens, holographic pods, all-in-one kiosks and websites, and is also sold as an API and as private deployments. In August 2025 a BOTA kiosk with a 3D cartoon digital human, Xiaolu (小鹿), developed by its subsidiary Shiyou Universe (Chengdu) Technology Co., Ltd. (世优宇宙（成都）科技有限公司), guided visitors at the Chengdu Natural History Museum in the city’s real-world trials of robots and AI (Chengdu Daily). In October 2026 the company passed the national review of its Specialized and New “Little Giant” status.
