ZETTAi

What ZETTAi does

ZETTAi (株式会社ZETTAi) is a Tokyo-headquartered private company incorporated on July 22, 2025, that delivers corporate AI reskilling programs built around Anthropic's Claude Code coding agent. The company's core offering, the Claude Code研修 (Claude Code Training) platform, teaches non-engineering business professionals to design, build, and deploy production-ready internal business tools in 10 days without writing code manually. The program is delivered in three primary formats — a self-paced E-Learning course priced at 50,000 JPY per participant, an in-person Offline Bootcamp at 100,000 JPY per participant (2-10 days plus 4 weeks of post-training accompaniment), and a customized Enterprise plan sold by individual quotation (covering 30+ participants across cohorts, with SSO, closed network, NDA, and dedicated CS support). A small-group 塾 (juku) format targets absolute beginners.

The underlying technical stack standardized across the curriculum comprises Claude Code as the primary AI agent, Supabase for database and authentication (Tokyo region, SOC 2 Type II), Vercel for hosting (SOC 2 Type II, ISO 27001), GitHub for artifact management, and Render for deployment. A proprietary LMS with a 3-screen interface (Dashboard, 39-stage Stage Map, GitHub pane) supports live instructor accompaniment via Zoom. ZETTAi complements training with recurring post-sale maintenance contracts in three tiers (Light 100,000 JPY/month, Standard 200,000 JPY/month, Pro 300,000 JPY/month, minimum 3-month terms) and a talent-matching service that introduces corporate customers to a database of 100+ Claude Code practitioners for hire, dispatch, or contract engagements.

ZETTAi sells through a sales-led, event-driven go-to-market motion anchored on weekly free Google Meet seminars, with a free 30-minute consultation as the primary conversion mechanism into training contracts. The customer base of 127 corporate clients spans advertising (Fines Co., Ltd.), IT trading (WIZ), and marketing/IS (XiM); the company reports an 88% non-engineer participant mix, a 99% e-learning completion rate, a 4.8/5.0 satisfaction score, and an 85% rate of clients continuing into paid maintenance after the 30-day free post-training chat period. The company is bootstrapped and founder-owned, with no disclosed external funding; it operates from Azabujuban, Minato-ku, Tokyo, with 29 employees as of the latest company profile.

Revenue model

1. Training Program Fees: ZETTAi generates revenue primarily through paid training programs. Three core training formats exist: E-Learning (online, self-paced, 10-day program, 50,000 JPY per person), Offline/In-Person Bootcamp (2–10 days face-to-face + 4-week post-training accompaniment, 100,000 JPY per person), and Enterprise (custom multi-department, multi-cohort programs, quoted individually). Additional revenue comes from monthly maintenance/support plans (Light 100,000 JPY/month, Standard 200,000 JPY/month, Pro 300,000 JPY/month, minimum 3-month contracts). A talent database subscription for matching Claude Code engineers with enterprises (introduction, dispatch, outsourcing) also generates fees. Payment is primarily invoice-based (bank transfer) with credit card options for E-Learning.

Scale indicators6 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Udemy Business: Udemy Business is a global enterprise learning platform offering thousands of on-demand courses including rapidly expanding AI and Claude Code content. It is a broad incumbent competitor for corporate AI training budgets, particularly in self-paced learning categories, and benefits from global scale and content breadth that ZETTAi cannot match.
• Skillsoft: Skillsoft is a long-established enterprise learning platform offering AI, tech, and leadership training through subscription. It competes with ZETTAi for corporate training budget allocation, with particular strength in large-enterprise procurement relationships, though its content delivery model differs significantly from ZETTAi's intensive in-person bootcamp.
• Coursera for Business: Coursera for Business partners with top universities and AI labs (including DeepLearning.AI and Anthropic-published content) to deliver enterprise AI training. It competes for the same corporate AI upskilling budgets as ZETTAi, with a much larger content catalog, enterprise SSO, and global brand recognition.
• General Assembly: General Assembly (now part of Adecco) is a global leader in corporate tech reskilling, with bootcamps and enterprise training across data, software engineering, and AI. Its immersive bootcamp format and corporate reskilling focus are directly comparable to ZETTAi's value proposition, though its scope is much broader than Claude Code specialization.

Emerging players

• DataCamp: DataCamp is a leading data and AI skills platform serving both individuals and enterprise customers, with structured curricula on Python, data science, and increasingly AI tooling. It is comparable as a corporate AI training subscription product and represents a partial overlap with ZETTAi's enterprise audience, though less focused on AI coding agents.
• DeepLearning.AI: DeepLearning.AI (Andrew Ng) produces short-form AI courses that enterprises increasingly adopt for AI upskilling. While it currently focuses on conceptual AI/ML training rather than Claude Code-specific deployment, it represents an emerging AI-first competitor for corporate AI literacy budgets and could expand into AI coding agent training.

Regional players

• ABEJA: ABEJA is a Japan-based AI platform and consulting company that also operates corporate AI training and DX support programs for Japanese enterprises. It is comparable as a Japan-focused regional player combining AI services with training, though its primary business is platform/consulting rather than dedicated AI coding training.

Direct peers

• Code Chrysalis: Code Chrysalis is a Japan-based (Tokyo) immersive coding bootcamp that trains non-engineers and career changers to become software developers in a short, intensive format. While its curriculum centers on traditional programming rather than AI coding agents, its target persona (non-engineers) and intensive bootcamp delivery model closely mirror ZETTAi's 10-day approach.
• TechAcademy (by Diverta): TechAcademy is one of Japan's largest online programming bootcamps, offering mentor-supported courses for beginners and corporate training plans for Japanese enterprises. It competes with ZETTAi on the non-engineer corporate training persona, course format, and Japan market, though its curriculum is broader and not AI-coding-agent-focused.
• AVILEN: AVILEN is a Tokyo-based AI solutions and education company offering corporate AI training programs and DX support. It is the closest Japan-market direct competitor to ZETTAi, with overlapping target customers (enterprise HR/DX departments), similar bootcamp-style delivery, and comparable focus on practical AI implementation rather than theoretical instruction.
