Failure Analysis
17zuoye's death was a regulatory execution, not a market failure. On July 24, 2021, China's State Council issued the 'Double Reduction' policy, banning for-profit...
17zuoye \China
17zuoye (literally '17 Homework') was China's largest K-12 online homework and adaptive learning platform, serving over 50 million students, 4 million teachers, and 40 million parents at its peak. Founded in 2011 by Liu Chang (former Sina executive), the platform digitized homework submission, automated grading, and provided AI-powered personalized learning paths. The value proposition was compelling: reduce teacher workload through automated grading, give students instant feedback with gamified learning, and provide parents real-time visibility into academic progress. The 'Why Now' was perfect timing with China's mobile internet explosion (2011-2015), rising middle-class anxiety about education, and government push for education technology. With $585M from tier-1 investors like DST Global and Temasek, 17zuoye became the poster child for Chinese EdTech, achieving unicorn status by 2018. The platform combined homework management, adaptive question banks, live tutoring, and a freemium-to-premium conversion funnel. However, the business model was fundamentally vulnerable: it relied on converting free school users to paid after-school tutoring services, creating a regulatory time bomb in a sector where the Chinese government maintains tight ideological control.

Rebuild & monetization strategy: Resurrect the company
Execution Plan
Phase 2
Step 2 - Validation and Feedback Loop (Months 4-6): Add essay grading (English, history) using Claude 3.5 with custom rubrics. Launch a freemium web app (free for individual teachers, $15/month for advanced features like custom question banks and parent reports). Conduct 50+ teacher interviews to identify the killer feature for school-wide adoption. Metric: 5,000 teachers, 100 paying subscribers, NPS > 50.
Phase 3
Step 3 - School Sales and LMS Integration (Months 7-12): Build deep integrations with Canvas and Schoology (not just Google Classroom). Launch school-wide licenses ($5,000-$20,000/year based on school size). Hire 2 inside sales reps to close deals with district administrators. Create ROI calculator showing time savings (teachers save 10 hours/week = $15,000/year in labor costs per teacher). Metric: 50 school contracts, $500K ARR.
Phase 4
Step 4 - Moat and Expansion (Year 2+): Become the system of record for homework data by adding features schools can't live without: predictive analytics (identify at-risk students before they fail), curriculum alignment (map homework to state standards), and parent portals (read-only access to student progress). Expand to India and Southeast Asia with localized content. Build a marketplace for teacher-created question banks (take 20% commission). Metric: $5M ARR, 500 schools, 50,000 teachers, path to $50M ARR within 5 years.
Monetization Strategy
Three-tier model: (1) Free Tier - Individual teachers get basic auto-grading for up to 100 students, limited to multiple-choice and short-answer questions. This is the viral wedge. (2) Teacher Pro ($15/month or $150/year) - Unlimited students, essay grading, custom rubrics, parent reports, priority support. Target: 10-20% conversion from free tier. (3) School/District Enterprise ($5,000-$50,000/year) - School-wide licenses with SSO, LMS integration, admin dashboards, dedicated onboarding, and SLA guarantees. Pricing scales with school size (small schools $5K, large districts $50K+). Additional revenue streams: (a) Marketplace - Teachers sell question banks, we take 20% commission (similar to Teachers Pay Teachers model). (b) API Access - Sell grading API to other EdTech companies at $0.10 per graded response. (c) Data Licensing - Aggregate anonymized homework data to sell insights to curriculum publishers (with strict privacy controls and opt-in consent). Target unit economics: CAC $500 (bottom-up viral + inside sales), LTV $3,000 (3-year average retention for schools), LTV:CAC ratio of 6:1. Gross margins of 80%+ (pure software, LLM costs are $0.01-$0.05 per graded response). Path to $50M ARR within 5 years with 500-1,000 schools.
