EngineerDaddy

Shanghai Tongrui Network Technology Co., Ltd., operating under the brand EngineerDaddy (idaddy.cn), is a multifaceted children's content operations platform in China. The company was established on August 18, 2011, with Li Wenhua serving as the legal representative. It focuses on delivering comprehensive growth services related to reading and language development for Chinese children and adolescents.

The company's core offering is a cloud-based platform named "Pocket Story," which provides licensed audio content for children up to 12 years old. The content library is extensive, featuring fairy tales, nursery rhymes, Chinese classical literature, international masterpieces, and children's music. This service was developed in response to the observation in 2012 that audio-visual apps, such as those with songs, stories, and audiobooks, consistently dominated app store rankings, indicating a strong market demand for audio-based children's content. In addition to content for children, EngineerDaddy also provides parenting lectures from experts to guide parents in their educational methods.

The business operates in the online education and digital content market, specifically targeting families with young children. Its revenue model is centered on the paid subscription and consumption of its digital products, a strategy it pursued even when the paid adoption rate for children's apps in China was extremely low. Beyond its direct-to-consumer offerings, the company engages in technology development, consulting, and services in the fields of network, computer, and electronic technology.
