ISID-AO was strategically established in 2009 as a part of the ISID group, a joint venture between the worlds largest advertisement company, Dentsu, and one of America’s leading companies, General Electric Company (GE).

Our mission is to contribute to the development of our clients’ businesses and society through creating platforms for industrial and technological innovation by bringing together experts from the fields of digital infrastructure, system support, and user support.

We believe in “X (Cross) Innovation”; we aim to go beyond the limits of ideas such as technology, industry, a company, an organization, or location, and use synergy to innovate new products that bring value to the world.

Dentsu and ISID’s Group DNA

ISID-AO was established in 2009 as a part of the ISID group that provides IT solutions for the Dentsu group. We are unique even to the Dentsu group in that we are the perfect mix of robust experience, something only large corporations bring to the table, combined with the kind of diversity and youth associated with start-ups.

A Group of Professionals Well-Versed in Their Fields

The engineering process is key to bringing innovation to manufacturing. Platforms for organizing human resources and administration are at the heart of business activities. It wouldn’t be possible to create a system for a specialized business operation without insight from a specialist in its field. We offer experts who know your business and will work with you. This is where we excel.

Creating Long-Term Partnerships With Our Clients

We work with many large corporations, including leading domestic manufacturers, and provide them with comprehensive support for the entire life cycle of their IT systems. This creates a long-term, tight-nit partnership, which allows us to really grasp the challenges our clients face and provide them with real solutions.
