Spike Studio

What Spike Studio does

Spike Studio Co., Ltd. (株式会社スパイクスタジオ) is a Tokyo-headquartered generative AI services and product company founded in 2023 by CEO Shigeru Kuroyanagi (formerly of Microsoft Japan and Facebook Japan) and COO Hirohide Sano. The company serves Japanese enterprises across manufacturing, finance, retail, and adjacent verticals, helping them move generative AI from pilots into production through a portfolio of four service modules — Generative AI Utilization Support (literacy training, ideation workshops, PoC, advisory), AI Integration (custom generative AI and ML/DL system development), AI Quality Monitoring/Management (governance, filtering, testing, real-time surveillance), and Generative AI Outsourcing (prompt engineering and data annotation) — and two verticalized software products: Densapo, a real-time telephone support AI for call centers, and Flowbase, an AI-powered manual auto-generation platform. The business model is primarily professional services and managed services, quote-based and tailored per engagement, with the growing software product line introducing a recurring component.

Under the hood, Spike Studio operates as a multi-agent AI integrator rather than a model builder. Its technology stack combines third-party large language models with proprietary orchestration, prompt engineering, and AI safety middleware that handles data masking, encryption, access control, audit logs, input filtering, sanitization, and real-time monitoring. Densapo combines real-time conversation transcription with knowledge retrieval over internal manuals and databases, while Flowbase applies multimodal AI to screen recordings to auto-generate step-by-step procedures. The go-to-motion is enterprise field sales supported by event-driven demand generation at Japan's major DX exhibitions (DXPO Tokyo, DXPO Nagoya, もの fabrica World) plus content marketing through case studies and white papers. Marquee customers include Toyota Motor Corporation, NTT DX Partner, and Sumitomo Mitsui DS Asset Management, and the company reports having trained over 2,000 employees at major corporations.
