What SAILING does

SAILING Inc. (株式会社セイリング) is a Tokyo-based Japanese IT infrastructure services company founded in 1997 and operating as a wholly-owned subsidiary of Human Creation Holdings (HCH), a TSE Growth-listed group that consolidates approximately 938 employees as of September 30, 2024. The company delivers five core service lines — Training Services, Digital Engineering (FPGA/ASIC + embedded C), Platform Business (cloud, monitoring, security operations), Infrastructure Management (server/network monitoring and operations), and Network Security — to enterprise clients across financial services, energy/utilities, manufacturing, and telecommunications. SAILING employs approximately 70 engineers and operates a dual-support model in which sales representatives concurrently manage client/project development and engineers' career development.

The underlying technology stack spans network and switch infrastructure design, server design/construction/maintenance, cloud environments on AWS and Azure, digital engineering combining FPGA/ASIC circuit design with embedded C programming, and modern application development using Vue.js front-ends backed by AWS serverless components such as Lambda, API Gateway, and DynamoDB. Documented client outcomes include a roughly 50% reduction in master-data-update work hours at an electric-power retailer following a centralized business-application rollout, and a phased migration of approximately 300 branch offices from on-premises PBX to cloud PBX at a life insurance company. The company has held Privacy Mark certification since 2014 under JIS Q 15001.

SAILING's business model is professional services–based and sales-led, monetizing through (1) engineer dispatch and staffing to enterprise client sites for system construction, operation, and maintenance; (2) bespoke project work including cloud migration and DX initiatives, often led by group company ACF; and (3) customized training programs for embedded software and IT infrastructure charged on a contract basis. Pricing is not publicly disclosed and is negotiated per project; engineer compensation is salary-based at a minimum of ¥197,800 base plus ¥31,000–¥46,800 fixed overtime allowance per month. Distribution is domestic-only within Japan's Kanto region, delivered through direct B2B sales engagement with no disclosed international footprint. Marketing is anchored on the corporate website (sailing.ne.jp), employer branding content, and group-level communications rather than outbound demand generation.
