Nantong Haixin Intelligent Technology, a tech startup that launched in Rudong county, Nantong, Jiangsu province, in 2024, has surpassed 100 million yuan ($14 million) in sales within just two years, securing a top-three position in the crowded mobile smart screen market in China.

Its flagship product — a mobile smart screen known as the "Bestie Screen" — stands out not for gimmicks, but for real innovation.

The name came from a simple idea: the device accompanies users through fitness, cooking, binge-watching, and chatting, like a personal bestie, said Li Donghong, the company's general manager.  

The brand targets users of all ages and a range of family needs, from home companions and elderly care assistants to children's learning tools.

Behind the brand lies a high-standard dust-free workshop and proprietary research and development. Staff must wear dust-free suits and pass through air showers before entering the automated production line. Haixin has filed 16 patents, six of which have been granted, spanning lift brackets, battery protection, and anti-tilt structures. It has also introduced a high-capacity, low-power battery offering four hours of continuous use.

Since 2023, the mobile smart screen market has been expanding at an average annual rate of 200 percent, with giants like LG, Baidu, and Hisense piling in. Haixin has differentiated itself by diversifying into home, campus, outdoor, and commercial scenarios, operating e-commerce platforms for domestic consumers, customizing products for education and corporate events, and expanding globally via Amazon and Alibaba International.
