Gaotu Techedu is a China-based online education company offering tutoring and learning services to K-12 students, college students, and adults. Gaotu's core product is live-streamed tutoring using a "dual-teacher" or "tri-teacher" model, where a lead instructor delivers lectures to large groups while a separate team of tutors provides smaller-group support. AI tools handle routine tasks like grading and answering repetitive questions, freeing teachers for higher-value instruction. Gaotu sells directly to students and parents through its website and mobile apps, using a funnel model: social media content generates leads, which Gaotu converts through free or discounted trial classes before upselling to full-price courses. Learning services account for over 95% of revenue, with non-academic tutoring and traditional academic subjects (math, Chinese, English, sciences) for K-12 students making up over 80% of total revenue. College and adult education — covering exam prep, civil service coaching, and career English — contributes over 15%. Gaotu is also expanding into offline learning centers, launched in 2023, which recently exceeded 10% of revenue and are expected to reach school-level profitability in 2026. Gaotu collects tuition upfront and recognizes revenue as courses are delivered, creating a deferred revenue balance that provides near-term revenue visibility. Gross margins run in the mid-to-high 60% range, with selling expenses (roughly 50-60% of revenue) as the primary cost. Longer-term, Gaotu aims to be a "lifelong learning platform" spanning primary school through adult professional development.
