Proassist, Ltd.

Proassist, Ltd. is an Osaka, Japan-based software and engineering company founded on April 25, 1994. With 180 employees as of 2026 and a subsidiary in Suzhou, China (Proassist Suzhou, Ltd.), the company provides custom software and engineering services across three main business segments: embedded system development, control system development, and business system development.

In the control and embedded systems domain, Proassist develops real-time device control software for industrial equipment, medical devices, and IoT systems. The company holds patents in ultrasonic sensor signal processing (2007, 2020), sickbed departure alarm prediction (2012), flow-line measurement systems (2013), sleep-state determination and dozing prevention devices (2017), delivery condition monitoring systems (2019), and ultrasonic array sensor systems — demonstrating sustained R&D activity across sensor-driven healthcare and industrial applications.

Proassist's healthcare segment includes manufacturing and marketing of specially-controlled medical devices and second-class medical devices under licenses issued by Osaka and Tokyo business offices. Their medical device portfolio includes wearable and monitoring systems for senior care and rehabilitation settings, where embedded sensor solutions support patient safety and mobility tracking.

Engineering services include dispatching skilled engineers to client sites for hardware development, control software programming, and mobile application development. The company also offers cloud services for education and training and AI application development, the latter built on its long track record in embedded software.

Proassist has received recognition including the Osaka City Excellence Company Award (2012), METI's Top 300 Most Aggressive SMEs (2013), and the FY 2014 Diversity Management 100 Award. The company works with clients in manufacturing, healthcare, and logistics sectors. Its Technology Collaboration Agreement with Tata Elxsi (2008) facilitated cross-border engineering support.

While Proassist does not manufacture physical robots, it is a software and algorithm supplier relevant to the robotics ecosystem — providing embedded control software and healthcare device development services used in automation and assisted-living systems.
