CyberAgent

One of Japan's largest domestic digital advertising and internet media companies with a full-stack AdTech offering

CyberAgent, Inc. is a Tokyo-based internet conglomerate founded in 1998, best known in Japan for operating Ameba (a blogging and social platform), the AbemaTV streaming service, and a comprehensive suite of digital advertising and marketing technology products. The company has grown into one of Japan's most significant digital media and AdTech companies, with its Internet Advertising segment being a core revenue driver alongside its media and game businesses. In the AdTech space, CyberAgent operates AI Lab-powered advertising solutions, a demand-side platform (DSP), and a full-stack digital marketing services division. Its subsidiary CyberAgent, Inc. (through brands like Dynalyst and AI Ads) provides programmatic advertising, retargeting, and performance marketing solutions to brands and agencies across Japan and increasingly in Asia. The company is known for integrating AI and machine learning into its ad products, particularly for creative optimization and audience targeting. CyberAgent is publicly traded on the Tokyo Stock Exchange and commands a significant share of Japan's digital advertising market. Its media properties — including AbemaTV, which has grown into a major streaming platform — provide first-party data and inventory that strengthen its advertising ecosystem. The company competes with global players like Google and Meta in Japan while also partnering with them, and it remains one of the few domestic Japanese companies with a full-stack advertising technology offering.
