## About

Founded in 2016 by CEO Tomo Ishikawa and based in Tokyo, Japan, Spiral Inc. engaged in the design, development, and provision of drones and drone services to assist in checking tunnels and dams. In August 2024, Spiral Inc. raised JPY 300 million in pre-series A funding from investors Mitsubishi UFJ Capital and NIPPON EXPRESS HOLDINGS.


Spiral Inc.'s primary product is the MarkFlexAir system, an automated patrol solution designed for indoor environments. This system enables drones to recognise markers placed within a facility, allowing for precise autonomous navigation. The system supports various applications, including inspection, monitoring, and data collection in complex indoor infrastructures such as tunnels, dams, and construction sites. The company provides comprehensive solutions, from flight design to image analysis, tailored to the specific needs of different environments.


The August 2024 investment aims to accelerate the global expansion and mass production of Spiral's non-SLAM indoor drone systems for autonomous flight.
