What Airstage does

Airstage (AIR STAGE CO.LTD.) is a privately held Japanese IT services company founded in February 2004 and headquartered in Takadanobaba, Shinjuku-ku, Tokyo. The firm operates a four-domain service portfolio—Infrastructure Services, Software Development, AI Integration, and SOC (Security Operations Center) Operations—delivered through direct enterprise sales to mid-market and large Japanese enterprises. It differentiates by providing end-to-end responsibility across infrastructure, application development, AI implementation, and security monitoring under a single vendor, eliminating the multi-vendor fragmentation common in Japanese enterprise IT. The company reports a 100% repeat customer rate, partnerships exceeding 20 years with major enterprise clients, and a stated 80%+ technical certification rate across its 45-person team. Representative Director and CEO Kishi Mutsumi (岸 睦) leads the firm, which appears to be founder-controlled with no disclosed external institutional investment.

The company's technical footprint spans multi-cloud infrastructure (AWS, Azure, GCP) with Microsoft 365 / modern workplace capabilities, custom application development using Java, Python, Go, React, Vue.js, and TypeScript on Docker/Kubernetes with CI/CD, and a Security Operations Center built on Microsoft Sentinel SIEM plus UEBA, SOAR, EDR/XDR, and global threat intelligence. AI Integration is built on a multi-LLM architecture (OpenAI GPT, Anthropic Claude, Google Gemini) orchestrated via LangChain for autonomous multi-agent workflows, with RAG-based secure knowledge retrieval from internal documents. Delivery leverages a Japan-Vietnam hybrid model in which Japanese teams handle requirements definition and project management while the Vietnam engineering center provides AI engineers and developers at a more competitive cost base. The company holds no patents, discloses no funding history, and reports no revenue figures; pricing is consultation-based with multi-year enterprise contracts.

Revenue mechanics derive primarily from professional services engagements (Infrastructure, Development, AI Integration) and a managed SOC services recurring stream. GTM is consultative and relationship-led, initiated through website contact forms and direct consultation rather than open marketing channels. The company's marketing presence is minimal—website, an official LINE account launched July 2025, and a recruitment site launched May 2025—indicating reliance on long-tenured client relationships and enterprise reputation over performance marketing. Operating geographies are Japan and Vietnam, with no claim of broader global footprint.

Core offering

AIR STAGE CO.LTD. (Airstage) is a Japanese enterprise IT services company providing four integrated service lines: Infrastructure Services (cloud, network, server, and client environment design and operations across AWS, Azure, GCP), Software Development (web, mobile, and business application development), AI Integration (multi-LLM enterprise AI with RAG and autonomous agents built on OpenAI, Claude, and Gemini), and Security Operations Center (SOC) services (24/7 log monitoring, SIEM correlation, UEBA behavior detection, and SOAR-driven incident response). The company delivers end-to-end IT responsibility for mid-market and large enterprises under a single-vendor model, supported by a Japan-Vietnam hybrid development structure.

Product overview

Airstage operates as a unified IT services company offering four interconnected core services: Infrastructure Services, Software Development, AI Integration, and SOC Operation. The portfolio is designed as an integrated system—AI Integration and SOC Operation are built upon the Infrastructure and Development foundations. The AI Integration service leverages multi-LLM architecture (OpenAI, Claude, Gemini), RAG knowledge retrieval, and autonomous agents to automate business processes, while the SOC service uses SIEM, UEBA, and SOAR tools for cybersecurity operations. Infrastructure and Development services provide the cloud-native and application development foundations that enable the AI and security capabilities. Together, these four domains allow Airstage to deliver end-to-end IT solutions from infrastructure design through AI-powered automation and security monitoring, eliminating vendor fragmentation through a single-source responsibility model.
