About Afficient Academy

Afficient Academy was founded in 2014 in Silicon Valley, CA. We are devoted to developing a new generation of education programs based on modern technologies to empower students to excel.

Our AI-empowered programs help students efficiently fill in gaps of previous years to build solid foundations, enable students learn and progress at their own pace and advance ahead of the school curriculum with high learning efficiency and quality. With our highly efficient learning programs, students achieve better grades in school, have less stress and gain more time for other activities.


Dr. Jiayuan Fang, the Founder & CEO of Afficient Academy was a professor of Electrical Engineering for more than 12 years at the University of California and at the State University in New York. He was also an entrepreneur of a highly successful technology company which was acquired a few years ago. Being a father of three children, he was heavily involved in his children’s education and had the opportunity to evaluate many afterschool education programs. Having experienced serious deficiencies in many existing after-school programs, he decided to start a technology-based education company that would focus on creating better education programs that can significantly enhance learning effectiveness.
