What 株式会社エクス does
株式会社エクス (EXS Co., Ltd.) is a private Japanese embedded software development specialist headquartered in Chiyoda-ku, Tokyo. Founded in 2005, the company employs 53 people as of April 2026 and provides custom embedded software, driver/firmware, and hardware design services spanning the full lifecycle from specification design through testing and mass production. Its customer base is concentrated in Japanese manufacturers across five verticals — mobility/automotive, medical/healthcare, AV equipment/cameras, social infrastructure, and IoT & AI — with automotive-quality development processes a stated point of differentiation.
The company operates three core service lines: embedded software/hardware development, application development (Windows/Linux PC and Android/iOS smartphone), and cloud software development on AWS and Azure. On top of the professional services base, EXS has begun productizing two proprietary assets: PitDX, a subscription vehicle-inspection DX platform for car dealers launched in January 2022, and Comm Crow, a CAN communication tool for automotive and embedded testing released in 2025. Process maturity is documented through CMMI-DEV Level 2 (2016), ISO 9001:2015 (2021), and ISO 27001:2013 (2021) certifications.
Revenue is generated primarily through custom-quoted professional services engagements sold via direct sales to enterprise customers in Japan, with no public pricing and no disclosed revenue figures. Distribution is single-country (domestic Japan, Tokyo metropolitan area), and go-to-market relies on the corporate website, direct inquiries, and partner referrals rather than channel partners. The business model is overwhelmingly project-based services with two nascent productized recurring-revenue streams (PitDX subscription, Comm Crow licensing) that are immaterial to current scale relative to services revenue.
