eSOL Acquires Kyoto Microcomputer as Subsidiary
— Helping Realize Cyber-Physical Society and Enhancing Corporate Value by Leveraging Powerful Synergies to Strengthen eSOL’s Full Stack Engineering Strategy —
Tokyo, Japan, 8 August 2025 – The Board of Directors of eSOL Co., Ltd., a global leader in embedded software and edge computing solutions, today resolved to acquire KMC Holdings Co., Ltd. (Headquarters: Nishikyo-ku, Kyoto-shi, Kyoto-fu, President & CEO: Daisuke Sato) as part of the eSOL Group through a simplified share transfer. KMC Holdings and its subsidiaries (Kyoto Microcomputer Co., Ltd. and KMG Co., Ltd.) will formally become part of the eSOL Group as of Wednesday October 1, 2025, the date of the share transfer. (Hereafter, the three companies are collectively referred to as Kyoto Microcomputer (KMC).)
With particular expertise in debugger and compiler technologies, KMC is engaged in the development and sale of hardware and software for development environments, including debugging with Joint Test Action Group in-circuit emulators (JTAG-ICEs), analysis tools, open-source software (OSS) based compiler products, and SDKs based on an OSS real-time operating system (RTOS).
KMC will now become part of the eSOL Group, where the incorporation of KMC products and technologies that are expected to deliver powerful synergies should further strengthen the group’s pursuit of full-stack engineering. Integration of the two vendors’ respective OS SDKs should also enhance corporate value by delivering cost optimization and by expanding both our business infrastructure and scope of operations.
The three KMC companies will continue to operate as separate entities after the acquisition and there are no current plans to discontinue any KMC products or services.
“I am sincerely delighted to be welcoming KMC into the eSOL Group just as it is marking the 40th anniversary of its founding. This year is eSOL’s own 50th anniversary and I am confident that, as two organizations that have long participated in the growth of the embedded software industry, our respective technologies and expertise will prove a great advantage as we enter a new era of manufacturing, further strengthening our full stack engineering strategy and making a major contribution to realizing a cyber-physical society,” said Masaki Gondo, CEO, CTO, President, and Representative Director of eSOL.
As the IoT becomes ever more ubiquitous, with data collected in cyberspace being exchanged across a wide range of sectors, it is both enriching our lives and helping us overcome the societal challenges we face. The eSOL Reborn 2030 - Strategic Business Plan announced on April 30, 2025 lays out eSOL Group’s medium-term plans based on a vision of becoming a world-class full-stack engineering company engaged in realizing a cyber-physical society for the people of the world. This involves offering world-class full-stack engineering that leverages our expertise in functional safety and high-performance computing technologies. We combine high efficiency and low power consumption with our extensive experience in embedded software development. This allows us to operate as a total provider with capabilities that cover every system layer (platform, OS, and application) while also encompassing tool chains and processes. By doing so, we are helping to put the “software-defined everything” (SDx) approach to manufacturing into practice as we work toward realizing a cyber-physical society for the people of the world.
