MC3

What MC3 does

MC3 (Magna Computer Consulting & Communications Co., Ltd. / 株式会社エムシーキューブ) is a small Japanese IT services company founded in 1998, headquartered in Izunokuni, Shizuoka Prefecture, and operating as the core engineering entity of the MC3 Group under holding company MC3 HD. The company provides custom software development services to enterprise clients in finance (securities, life and non-life insurance, defined-contribution pensions), public sector (postal services, government bodies), manufacturing (electrical equipment), and education, using a full-lifecycle delivery model with client-resident engineers (常駐) handling requirements, design, development, testing, and ongoing maintenance without external vendor handoffs. Its technology stack spans legacy (COBOL, VB.NET) through modern web/cloud systems (Java, C#, Vue.js, AWS Aurora/PostgreSQL).

The company operates three revenue streams: (1) commissioned custom software development contracted per project; (2) labor dispatching of IT engineers under Ministry of Health, Labour and Welfare permit 派22-300600, currently dispatching 5 workers to 2 clients at an average daily rate of ¥36,477 with a 50.70% margin; and (3) security consulting supporting SMEs in obtaining and maintaining PMS (Privacy Mark) and ISMS (ISO 27001) certifications. The group's proprietary cloud product solper.org, launched in 2020, packages PMS/ISMS compliance documentation management as a subscription or one-time offering. The Tokyo-based subsidiary RayJourney (renamed November 2019) extends the group into Tokyo enterprise engagements.

Go-to-market is sales-led and inbound-driven through the corporate website and parent company inquiry forms, with thorough requirements discovery (ヒアリング) before bespoke contracting. The company holds PMS No. 21000022 (since 2007), ISMS IS537078 under ISO/IEC 27001:2022 (since 2008), and the worker dispatch permit (since 2016). Revenue and detailed financials are not publicly disclosed; the firm reports approximately 20% revenue growth and 66% headcount growth over the past five years, alongside a 97% three-year retention rate for new graduate hires.
