Teach

What Teach does

Teach Inc. (株式会社Teach), founded in January 2023 and headquartered in Osaka, Japan, operates a mobile-first online tutoring matching marketplace that connects parents and students with individual tutors. The platform covers elementary through high school students and is oriented around Japan's competitive entrance exam cycles — 中学受験 (junior high entrance), 高校受験 (high school entrance), and 大学受験 (university entrance) — as well as general academic support and occasional on-demand tutoring. Users discover, evaluate, and book tutors via native iOS and Android apps plus a web portal, with teacher profiles displaying university background, ratings, hourly rates, and availability; sessions are delivered through a proprietary browser-based video classroom that supports screen sharing and PDF exchange without external tools like Zoom.

The underlying technology stack combines a teacher-matching algorithm, a built-in video lesson system, in-app messaging, a post-lesson structured review feature, and integrated credit-card payment processing. The product is augmented by Teach Concierge, an AI-powered customer support chat that delegates answer generation to an external Anthropic LLM, and by a Repro MA-powered email automation integration for behavioral-triggered engagement.

Teach monetizes via transaction fees on each tutoring session: teachers set hourly rates within a ¥1,500-¥3,000 band, the platform takes a 30% system commission on the teacher reward plus a 20% system usage fee, and the consumer-facing price per 60-minute session starts at ¥1,995 with an average around ¥2,700. There are no subscriptions, enrollment fees, or cancellation fees. Go-to-market is product-led growth: the app handles the full customer journey from discovery through payment, acquisition relies on SEO-driven content marketing (a Japanese-language blog and exam-prep articles), app store presence, testimonials, and word of mouth, and there is no field sales or institutional channel. As of May 2026 the company had raised ¥50 million in a Pre-Series A round led by Team Make C, reported 3,500+ active teachers, 10,000+ cumulative matches since launch, and a 90%+ repeat customer rate.

Revenue model

1. Tutoring Session Fees: Platform takes a commission on each tutoring session. Parents pay the teacher's hourly rate plus a 30% system commission (on the teacher's reward). Teachers set their own rates between ¥1,500-¥3,000 per hour. The platform also retains a 20% system usage fee from the teacher's earnings. This is a transaction-based model where revenue scales directly with lesson volume.
2. Marketing Services: Teach uses third-party email marketing automation (Repro) for customer engagement and onboarding communications.

Core offering

Teach operates an online tutoring matching platform that connects Japanese K-12 students (elementary through high school) with a network of 3,500+ tutors for one-on-one video lessons. Parents and students browse tutor profiles by subject, grade level, university background, and price, then book single 60-minute sessions starting at ¥1,995 with no enrollment, monthly, or cancellation fees. Lessons are delivered via a built-in browser-based video system with PDF and screen sharing, and are primarily used for entrance exam preparation including junior high school (中学受験), high school (高校受験), and university (大学受験) admissions.

Product overview

Teach operates as a unified online tutoring marketplace with two primary interfaces: a mobile app (iOS/Android) for students and parents to search and book tutors, and a web platform (t-ch.co.jp) serving as both marketing site and teacher management portal. The ecosystem includes a built-in video lesson system for real-time instruction, an AI-powered customer support chat (Teach Concierge), and internal marketing automation via Repro MA. Tutors manage profiles, schedules, and communications via the web platform, while students book sessions and attend lessons through the mobile app. Coverage spans elementary, junior high, and high school students across all subjects, including specialized entrance exam preparation (中学受験, 高校受験, 大学受験).

Direct peers

• Preply: Global online tutor marketplace with a similar commission-based matching model, transparent teacher profiles, and per-session pricing. Comparable business model to Teach though operating globally and more focused on language learning.
• Megastudy Online (メガススタディオンライン): Megastudy's online one-on-one tutoring service targets high-achieving students preparing for top Japanese universities. It directly competes with Teach in the high-school exam-prep segment with elite tutor branding.
• ManaLink: ManaLink is a Japanese online one-on-one tutor matching platform targeting K-12 exam preparation. It is the closest direct competitor to Teach, with a similar marketplace model, teacher profile browsing, and online video lessons.

Broad incumbents

• Toshin (東進ハイスクール): A major Japanese university-entrance prep school with an extensive online lecture platform. Overlaps with Teach on university exam preparation but delivers primarily recorded content rather than live tutors.
• Kawaijuku (河合塾): One of Japan's largest and most established university entrance exam prep schools with nationwide digital and in-person offerings. Overlaps with Teach on university exam prep and represents a potential partnership or competitive threat.
• Try Group (トライグループ): One of Japan's largest private tutoring and cram school operators, with online tutoring services under Try IT and Try Online. Competes with Teach across K-12 segments but via a hybrid in-person/online agency model rather than a pure marketplace.
• Studysapuri (Recruit): Operated by Recruit, Studysapuri is Japan's largest online K-12 and entrance-exam video course subscription service. It overlaps with Teach on target customers (junior high/high school exam prep) and online delivery, but uses a low-cost video library model rather than live tutor matching.
• Shinken Zem (進研ゼミ) - Benesse: Benesse's long-running K-12 correspondence and digital learning service. Competes with Teach for parent wallets on K-12 supplemental learning but via subscription workbooks/videos rather than live tutors.

Emerging players

• Surala (すらら): Surala offers adaptive AI-driven online learning for K-12 in Japan. It is an emerging alternative to live tutoring but targets similar K-12 exam-prep use cases with a non-tutor, content-led approach.

Others

• Wantedly (for tutor recruitment): While not a tutoring competitor, Wantedly is a key channel/ecosystem participant Teach relies on for hiring cross-functional team members and could leverage for teacher supply acquisition.
