Both companies aim to revitalize the programmatic advertising market through more comprehensive collaboration.
Comment from Sho Yamada, CEO of UNICORN Inc.
Until now, UNICORN has been promoting RTB connections with various SSPs in Japan and overseas. The collaboration with YieldOne® is extremely important in realizing the ideal world of programmatic advertising in the future. We will deepen our collaboration so that both parties can create solutions that will become commonplace in the future from a variety of perspectives, not just cookieless.
Comment from Takeshi Kobayashi, CEO of PLATFORM ONE Inc.
We are very happy that the RTB connection between Adways Group’s DSP “UNICORN” and YieldOne® has been completed, and that we can work together to invigorate the programmatic advertising market as a new partner on the supply side. UNICORN is a DSP that is also focusing on efforts to prepare for the post-cookie era. By collaborating with YieldOne®, which is also working in this area with Japanese media, we will be able to achieve high synergy in the post cookie era starting this year.
UNICORN will create an environment to concentrate on “Work that only humans can do” by reducing the time advertiser and advertising agencies spend on “detailed human operations and numerical analysis” that have traditionally been done, and continue to develop services with the mission of fundamentals of marketing to increase sales of products and services.
In addition, Adways Group will respond flexibly to market needs, strive to further expand its services, and realize the development of efficient and practical advertising marketing services around the world.
