T-THREE

What T-THREE does

T-THREE (ティースリー株式会社) is a Japan-based IT services and generative AI training company founded in 2012, headquartered in Saitama with a Tokyo branch. The company operates two interlinked business lines: long-running IT support services (help desk, technical support, IT asset management, and DX consulting) delivered to SMEs without dedicated IT departments, and a newer generative AI training practice launched in September 2025 under the AI SMART brand. The AI practice has expanded rapidly into a three-product series — AI SMART training (covering ChatGPT, Gemini, Copilot, and Claude), AI Coaching (a 3-month executive program launched February 2026), and AI BANSOU (a 88,000 JPY/month subscription retention service launched July 2026) — supported by a CAIO-led curriculum and a YouTube content channel with 28,000+ subscribers.

The company is privately held, founder/management-owned, and bootstrapped since inception with no external investment. It monetizes through a mix of recurring IT support contracts, per-participant AI training fees (275,000-330,000 JPY/person for flagship programs), subscription retention services, and engineer dispatching (SES). Customer acquisition relies on direct sales for IT support, consulting-led sales for AI training, and bi-monthly community IT exchange events. As of 2025-2026, T-THREE has supported 100+ companies and 1,000+ trainees across manufacturing, legal, medical, childcare, and public-sector segments, and has positioned itself as a regional SME flagship in Saitama, recognized by the Shibusawa Eiichi Spirit certification and Gold Diverse Work Style certification. The April 2026 establishment of the HR AI Lab Promotion Council with seven partner companies signals an intent to scale vertically into HR/labor/legal AI deployment advisory.

Emerging players

• ZERO Plus: Japanese AI training and DX support company targeting SMEs. Emerging competitor in the same niche segment as T-THREE's AI SMART, with similar Japanese SME focus.

Direct peers

• SkillUp AI: Japanese generative AI and data science training company offering corporate courses. Direct competitor to AI SMART in practical, application-focused AI training for working professionals.
• DataMix: Japanese data science and AI training provider serving corporate clients. Competes with T-THREE in the SME and mid-market AI upskilling segment with similar instructor-led program structures.
• AVILEN: Japanese AI/DX training and consulting firm offering corporate generative AI and machine learning education. Directly competes with T-THREE's AI SMART in the enterprise AI literacy segment with similar curriculum and instructor-led delivery models.
• Fixer Holdings: Japanese IT support and managed services company targeting SMEs without in-house IT teams. Closely mirrors T-THREE's IT Support division in defensive services (helpdesk, technical support) and offensive services (DX promotion).

Broad incumbents

• AI inside: Japanese AI platform company providing OCR, NLP, and generative AI products to enterprises. Adjacent rather than direct: competes with T-THREE's DX consulting on AI deployment, but as a product vendor rather than trainer.
• SAKURA Internet: Established Japanese cloud and IT infrastructure provider serving SMEs and developers. Overlaps with T-THREE's IT Support and SES offerings but operates at much larger scale and broader portfolio.
• BayCurrent Consulting: Major Japanese strategy and DX consulting firm. Overlaps with T-THREE's DX consulting and AI Coaching offerings but serves enterprise clients with broader transformation mandates.
• PKSHA Technology: Japanese AI platform company offering natural language processing and machine learning solutions to enterprises. Overlaps with T-THREE's DX consulting and AI coaching but as a much larger, product-led incumbent.
