Nezuku

What Nezuku does

株式会社ネヅク (Nezuku Co., Ltd.) is a Tokyo-based AI services company founded in October 2025 by representative Ikeuchi Kengo (池内 健悟), targeting Japanese small and medium enterprises (SMEs) under the stated mission of embedding AI as organizational culture rather than merely deploying tools. The company operates from Akihabara UDX in Chiyoda ward, Tokyo, and serves clients exclusively in Japan with no disclosed international footprint.

Nezuku runs two integrated business lines. The first is the AI Culture Program™ (AIカルチャー・プログラム™), a 12-hour online live lecture and workshop curriculum priced at 330,000 JPY per company, covering AI fundamentals, business efficiency applications, AI-driven data analysis, and company-specific challenge workshops built around each client's actual data. The second is a custom AI Solution Development service spanning no-code AI business automation tools (claimed to reduce development time by 60-70%), AI chatbots and internal assistants built on ChatGPT and Gemini against internal knowledge bases, AI-integrated web applications for customer management and inventory, and prototype/PoC support. The technology stack integrates with LINE and Slack for communication workflows and leverages Google's Gemini for predictive analytics such as churn correlation analysis. Multimodal AI is applied to advertising creative production, combining generated copy with design templates via Canva integration.

Revenue is generated entirely through professional services fees: the publicly listed 330,000 JPY per-company one-time training fee and quote-based custom development engagements with no disclosed pricing. Go-to-market is sales-led and direct, conducted online via the company website inquiry form and direct enterprise engagement, supported by content marketing through published case studies, corporate news updates, and event sponsorships. No revenue, headcount, funding, or named customer figures are disclosed in any source, and the company has been operating for only a short window since its October 2025 founding.
