At Ark System, our mission is to aim for coexistence and mutual prosperity as "the best partner for our customers." We have been involved in solutions across various industries such as construction, finance, public services, and distribution, engaging in system development and system consulting. We continue to provide proposals and support tailored to our customers' needs, building trust between people and growing together with our customers. Utilizing the technology and know-how cultivated through our business, we developed the "Rakuou" series of estimation software for construction operations. This software supports various industries, including architecture, electrical, and mechanical equipment construction, significantly streamlining the process from takeoff to estimate creation. Currently, it has been adopted by over 2,100 companies, including major general contractors. In addition to our flagship model "Rakuou 3," we also offer subscription versions that are easy to start and continue, such as "Rakuou Link" and "Rakuou Crew." For takeoff tasks, we provide "Hiroi-kun III," which allows for easy extraction of lengths, areas, and quantities with just a mouse click from drawings. We have also launched a subscription service that can be started casually from ¥3,800 (tax included) per month. We aim to improve our customers' operational efficiency and productivity, creating a comfortable work environment.
