What GSI does

GSI Co., Ltd. (株式会社GSI, Sapporo Securities Exchange ticker 5579) is a Japanese systems development company headquartered in Sapporo, founded in 2006. The firm operates across five Japanese offices (Sapporo HQ, Tokyo, Fukuoka, Osaka, Sendai) and a wholly-owned Philippine offshore development subsidiary, Be UNIQUE Inc., with consolidated headcount of 578 employees as of April 2025. GSI's revenue is generated across four primary streams: (1) resident and entrusted custom systems development delivered by engineers deployed on-site at client sites or via commissioned project work; (2) packaged software product sales comprising four proprietary or licensed solutions — CAP (an internal AI chat platform integrating ChatGPT, Gemini, and Claude with OCR and document features), UM SaaS Cloud (a Salesforce-built cloud ERP for manufacturing distributed in partnership with Synapse Innovation), Uレジ (a tablet POS system for food service), and GRANDIT (a web-ERP for medium/large enterprises); (3) digital design services for web/SEO and graphic production; and (4) the DX PARTNER fixed-fee digital transformation consulting service.

The business model blends professional-services revenue (personnel-based billing for resident/entrusted development) with recurring software revenue (UM SaaS Cloud, CAP, Uレジ subscriptions and licensing) plus resale margin on Google Workspace, which GSI distributes as an authorized reseller. Customers are predominantly Japanese enterprises in IT, manufacturing, healthcare/pharmacy, and food service, sold via direct sales engagement complemented by partner referrals through CTC and Hitachi Solutions channels. The company maintains full triple-stack compliance (ISO 9001 QMS, ISO 14001 EMS, ISO 27001 ISMS) plus PrivacyMark certification, and is recognized as a 1st-term Sapporo SDGs Advanced Company.

Capital structure consists of JPY 292M registered capital, listed equity on the regional Sapporo Securities Exchange, two outstanding series of unsecured corporate bonds (JPY 30M in 2014, JPY 50M in 2016), and a JPY 400M three-year commitment line facility with Hokuyo Bank established in March 2024. The company is majority controlled by founding leadership, with Masayuki Kudo (工藤 雅之) as Representative Director Chairman and Takanori Ozawa (小沢 隆徳) as Representative Director President since June 2022. GSI is operationally independent with no external private equity or parent holding company involvement.
