Two pillars for your AI transformation

AI Training Program

A hands-on, 10-hour training program spread over 2 months. Participants with zero programming experience master Claude Code through a 7-hour group training session plus three 1-on-1 follow-ups, building lasting skills they can apply on their own. The group session can be delivered in a single day or split across multiple days, based on your team's availability. Optional post-training continuous support (not subsidy-covered) helps them apply Claude Code to your own business challenges.

  • Non-engineers as the target audience
  • 100% hands-on Claude Code practice
  • Up to 75% government subsidy available (not guaranteed)
  • Optional post-training continuous support (separate from subsidized scope)

Custom AI System Development

We build AI-powered business tools tailored to your specific needs. From internal workflow automation to customer-facing applications, all delivered with full source code ownership -- no vendor lock-in.

  • Full source code ownership (buy-out model)
  • No vendor lock-in
  • Ongoing maintenance available
  • Eligible for government subsidies (up to 50%)

Pricing

Up to 75% government subsidy

Japan's Human Resource Development Subsidy covers up to 75% of AI training costs for SMEs. Extery handles the application process for you.

Standard price (5 participants)

~¥2.0M

After subsidy

~¥675k

Estimated cost for 5 participants assuming the maximum subsidy (¥300k per person cap × 5 = ¥1.5M expense subsidy + ¥50k wage subsidy, less ¥225k labor consultant fee). Approximately ¥135k per person (about 66% off). The subsidy is not guaranteed — actual amount depends on your company's eligibility and the Labor Bureau review. We provide a detailed estimate during the free consultation.

About

Founded by an AI practitioner

Yuki Sugimoto, CEO & Founder

After 8 years at a major Japanese IT firm (NTT Data, J.P. Morgan) as a systems engineer and project manager, Yuki founded Extery in February 2026 with a mission: making AI accessible to every small business in Japan.

Having witnessed firsthand how non-engineers struggle with digital transformation, Yuki developed a training methodology that enables anyone to build functional AI-powered tools -- regardless of technical background. The key insight: modern AI coding tools like Claude Code have eliminated the traditional barrier between "idea" and "implementation."
