Since its establishment in 1952, Yusei has accumulated a great deal of know-how through its extensive business operations including facilities management, cleaning, security and construction for office buildings and commercial facilities, while at the same time engaging in research into new technologies. For further growth in the future, the company is also considering promoting the digitization of its work and digital transformation efforts.

Yusei has set its eye on Platio, which enables users to build apps befitting specific in-house tasks without coding for a monthly fee of 20,000 yen, with no initial fees required, and decided to introduce the product in November 2021.

As the first project using Platio, Yusei built an app to keep tabs on the physical condition of workers during COVID-19 pandemic as an alternative to email- or phone-based daily reporting of the workers’ health status by e-mail or telephone. Yusei’s managing director, who had no programming experience, created its unique “health management app” in just three days without coding by himself, and deployed it for 40 employees at the Tsukuba office and the head office.

With the health management app, almost all reports can be made by selecting from a dropdown list; this process can be completed by anyone in just 10 seconds from a smartphone. The app combines a mental health check function in addition to body temperatures and other health conditions, providing more detailed information than the conventional reporting method. This has contributed to the maintenance and management of employee physical and mental health. Furthermore, those in charge of managing the app can now efficiently monitor the status of all employees remotely, leading to early detection of mental health problems.

Yusei also created an “employee safety confirmation app” as part of its Business Continuity Plan. At the request of an employee working on the frontline, the company also built a “business improvement proposal app” in about an hour; it has been put into operation. The company plans to continue to create original business apps that meet the needs of frontline workers, thereby promoting the digitalization of operations and DX.

A Message from Yusei

  • We expected Platio to serve as an “ignition” tool. First, I took the initiative in developing an app to raise employees’ awareness of the use of digital technology. I started the project with this in mind, and soon after an “app for business improvement proposals” was created based on an employee’s idea. This app allows employees to quickly notice problems in buildings and facilities they are entrusted to manage, make suggestions for improvement, and quickly share and address them.
    I developed the app in just one hour and deployed it on the same day. We believe Platio’s strength lies in its ability to bring ideas into shape.
    We intend to expand the use of Platio to other operations and locations in the future.
    Susumu Nemoto, executive director at Yusei Co.

Business Plan

Platio has been highly evaluated for its ability to create and deploy business apps unique to individual companies without coding in just three days, and adopted by companies and organizations in diverse industries.

As a result, sales almost tripled in FY2020, compared with the previous year, and this trend continues into the current fiscal year. The aim is to achieve 500 downloads by the end of FY2022.

*A mechanism which allows creation of software and apps without writing a single line of code. Platio users can deploy necessary functions and modify app’s specifications to make it more serviceable at worksites, even if they do not have expertise in a programming language.
