The desire to create a platform that enables anyone to have access to the cutting-edge technology

In 2015, I witnessed remarkable advances in technologies such as image processing, and foresaw that new software technologies would produce a variety of innovative products and services. We founded Idein with the desire to create a platform that makes it easy for anyone to use such latest technology.

I think the scope of software and the Internet that have changed our lives in the last 30 years will continue to expand. Advances in AI / IoT technology have made it possible for software to access information in various physical worlds such as people, things, and the environment. Idein is challenging to accelerate and support this transformation. As the first step, we have developed Actcast, a platform service that makes it easy for anyone to acquire various real-world information, and started providing it in January 2020.

In order for new technologies such as AI / IoT to become widespread and actually used, first of all, technical breakthroughs for important issues such as cost and privacy are required. Since its inception, Idein has been working on edge computing technology that enables us to reduce unnecessary communications and protect privacy. These include the distribution and remote management of software to a large number of edge devices, the integration of edge devices with cloud services, and the technology to perform advanced information analysis with the least expensive devices possible. In particular, we have the world's leading technology for accelerating AI (deep learning) on inexpensive edge devices.

Actcast is a combined service both with innovative concepts and the latest technology.

Secondly, we need a platform service that allows easy access to AI/IoT technologies from various vendors and Idein technologies. Currently, AI/IoT solutions for various issues are emerging from various companies, but user companies are exhausted by the situation where they have to somehow integrate and use multiple services consisting of different UI/UX, fee structures, devices and infrastructure to achieve their goals. The current concept of Actcast was born out of the need to have a marketplace and easy access to real-world information gathering applications from various vendors, to have a unified UI/UX, and to reduce costs by unifying devices and infrastructure to enable the use of high-level technology.

Unlike software that works according to specifications, it is difficult to evaluate the value of software that uses technologies such as AI/IoT, especially image analysis and voice analysis, until it is introduced into the field. The value of the data that can be obtained is often not known until it is actually taken. As with most Internet businesses, you need to be able to start small and grow through a process of repeated hypothesis testing. The concept of using the Raspberry Pi, an inexpensive and easy-to-use general-purpose computer, as the first supporting device, as well as the concept of remotely updating applications and charging per device per day, is based on such thinking.

We are proud to say that Actcast is a service that combines innovative concepts with cutting-edge technology. Although we just officially launched in January 2020, we have received interest from a variety of companies, including over 100 partners. We are constantly working to improve our services to make them easier to use and safer to meet your expectations. It is my dream that the ideas of users and vendors around the world will be tested on Actcast, and that these ideas will blossom to launch the next generation of various software industries. I would like to make efforts with my colleagues to realize this goal.
