Tokyo, June 23, 2021 ---D.A.Consortium Inc. (DAC) will work together with MediaMath, the global leader in programmatic ad technology, to establish a new company in Japan.

In recent years, there is an urgent need for programmatic advertising to respond to next-generation demands through the development of optimal services that comply with global standards, the promotion of common IDs and other initiatives. Against this backdrop, MediaMath, which leads the global programmatic advertising market, and DAC, a digital marketing company with online advertising and ad technology businesses in Japan and APAC countries, have agreed to develop a service infrastructure in Japan and collaborate further through the new company.

The new company, MediaMath Japan KK, will leverage the strengths of both DAC and MediaMath to introduce the latest technologies, such as Connected TV (CTV) and Digital Outdoor Advertising (DOOH), in Japan. In addition, the company will provide safe and secure advertising services to consumers and advertisers by improving the transparency of programmatic advertising, by strengthening privacy regulations and by popularizing and expanding a global, cookie-less standard in Japan.
