About Langbo

Langbo, operating under Beijing Boxue Tianxia Information Technology Co., Ltd. through langlib.com, is an ed-tech company focused on English language education. Founded in June 2007 by Dr. Du Changxu, a Tsinghua University alumnus, the company provides online learning solutions for standardized English tests such as TOEFL, IELTS, GRE, and SAT. The platform is built on what the company terms an "English ability graph," behavior data analysis models, and adaptive learning technology to offer personalized study plans.

The core of Langbo's service is a blended learning model that combines online methodology courses and an adaptive learning system with offline supervision and tutoring services. This approach is designed to enhance a user's comprehensive English abilities, covering grammar, vocabulary, pronunciation, and test-taking strategies. The business serves students preparing for overseas study and individuals aiming to improve their overall English proficiency.

Dr. Du Changxu founded the company after his time as a part-time teacher at New Oriental and during his doctoral studies at Tsinghua University's computer science department. He is joined by co-founder and CTO Jin Jing, and Vice President Peng Wenyu, who brought over a decade of experience in mobile product design from companies like Motorola, Baidu, and Shengda. Langbo has secured $9.18 million in funding over three rounds, with its most recent Series B round in September 2017 led by GF Xinde Investment Management.
