Origin
While pursuing his master's degree at Tsinghua University, Ma Min noticed that students lacked real-time feedback during reading. In June 2020, he co-founded Duihuayuan in Beijing with two classmates. The initial team consisted of only 3 people, and the first version of the AI reading app focused on instant Q&A and error review. In September 2021, a reading comprehension module based on GPT-3.5 was launched, marking the first successful implementation of paid subscriptions and commercialization. This validation, rooted in campus needs, laid the product and data foundation for subsequent school partnerships and the shift to B2B services.
Milestones
2020
Founding Turning Point
Ma Min co-founded Duihuayuan in Beijing with two Tsinghua classmates. With an initial team of only 3, they launched the first AI reading app, reaching 20,000 daily active users in the first month, which validated the market demand for instant Q&A and laid the foundation for future product iterations.
2021
Product-PMF Growth
The reading comprehension module based on GPT-3.5 was officially launched. In the first month, paid users exceeded 10,000, monthly paid revenue reached 300,000 RMB, and user retention hit 65%, marking the first commercial revenue.
2022
Series A Financing Growth
Secured $50 million (approx. 350 million RMB) in Series A funding led by Sequoia China, valuing the company at $200 million. Funds were used for model customization, content copyright, and team expansion, growing the team from 15 to 30 people.
2022
Product Failure Failure
Attempted to launch an AI writing assistant. Due to the lack of a precise writing evaluation model, the user complaint rate reached 12%, and the paid conversion rate plummeted to 3%. The company withdrew the feature within two weeks and refocused on reading scenarios, learning the lesson that 'more features do not necessarily mean better'.
2023
Series B Financing & Large-scale Deployment Growth
Completed a 200 million RMB Series B round led by Hillhouse Capital, with a valuation of $1.5 billion. The product partnered with education bureaus, integrating into 300 primary and secondary schools, with cumulative registered users exceeding 2 million and annual paid revenue breaking 100 million RMB for the first time.
2024
Policy Impact Response Turning Point
The 'Double Reduction' policy caused a sharp decline in demand for K12 online courses. Duihuayuan quickly pivoted to B2B corporate training and school-supporting services, launching an 'AI Teacher Assistant'. Quarterly revenue grew by 30% year-on-year, ensuring continued business growth.
Turning Points
- Technical breakthrough from zero-model implementation of ChatGPT to self-developed reading comprehension models
- The failure of the AI writing assistant led the company to return to its core reading business
- The 'Double Reduction' policy forced the business to shift from pure B2C to B2B and partnerships with educational institutions
Failures & Pitfalls
- In 2020, the MVP version suffered a 15% user churn due to server instability
- In 2022, the AI writing assistant feature was forced offline after user complaints skyrocketed
- Initial attempt at overseas market expansion was halted by local regulators due to compliance issues
关键成功要素
- Real-time AI reading Q&A
- Personalized learning path recommendations
- Bulk licensing model with deep integration into school systems
- Precise error analysis based on large models
- Closed-loop learning data synchronized across multiple platforms
Lessons
- Core features must be deepened before being broadened; blind expansion easily leads to user churn
- Technology selection must be combined with educational scenarios; simply applying general models has limited effect
- Policy changes are risks that education SaaS must reserve buffers for
- Financing pace must match product maturity; excessive early funding increases operational pressure
- Partnering with public educational institutions is key to opening scalable channels

Competitors / Peers
In the Chinese AI tutoring sector, major competitors include Yuanfudao, Zuoyebang, NetEase Youdao, and the emerging Take Education. Yuanfudao leads the K12 market with its powerful live teaching system; Zuoyebang relies on its massive question bank and AI grading technology; NetEase Youdao has deep layouts in language learning and AI writing; while Take Education focuses on AI speaking evaluation. Duihuayuan forms a differentiated competitive advantage by focusing on real-time reading Q&A, deep integration with school systems, and high-precision error analysis.
