Magicemi, a B2B Webinar Business, Joins ITmedia Group

Magicemi Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Yuichi Terada), which operates a B2B webinar business, announced on April 1st that it has transferred 100% of its shares to ITmedia Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and CEO: Norichika Kobayashi), a company listed on the Tokyo Stock Exchange Prime, and has become a member of the ITmedia Group.

As corporate information gathering and marketing methods change due to the spread of generative AI, Magicemi will leverage ITmedia's media member base to expand its B2B webinar business not only in the IT domain but also in the manufacturing and back-office sectors.

■B2B Webinars Become Crucial in the Era of Generative AI

The spread of generative AI is significantly changing how companies gather information. In addition to information gathering via search engines, there is an increasing trend of acquiring information through generative AI, and the structure of traffic to corporate websites is also changing.

Furthermore, the digital advertising market is seeing rising click-through rates, and in corporate marketing activities, there is growing interest in new lead acquisition methods that do not rely on search traffic or advertising.

In this context, webinars (online seminars) are attracting attention as a marketing method for companies to directly connect with potential customers and build relationships.

In particular, webinars that attract audiences by utilizing media and member bases are gaining widespread use as a method that does not rely on search traffic or advertising, and can be expected to stably acquire leads even in the era of generative AI.

Webinars, which allow companies to communicate directly with potential customers and build relationships, are one of the marketing methods whose importance is increasing in B2B marketing in the generative AI era.

■Approximately 2 Million Media Member Base × Over 1,000 Webinars Annually

Magicemi has a track record of operating over 1,000 webinars annually and has provided services that comprehensively support corporate webinars, including planning, audience acquisition, and operation, primarily assisting B2B marketing activities for IT companies. It also has a member base of over 200,000, supporting companies in lead acquisition through webinars focused on technology.

On the other hand, ITmedia operates numerous specialized media in IT, manufacturing, IT administration, and back-office domains, and has a member base of approximately 2 million.

By joining the group, Magicemi will further strengthen its webinar audience acquisition capabilities by utilizing ITmedia's media member base. By providing marketing support that combines media and webinars, the company will assist in corporate lead acquisition and business negotiation acquisition.

Furthermore, in addition to the IT domain, which has been its strength, Magicemi will expand its webinar business into the manufacturing and back-office sectors, thereby expanding the scope of its B2B marketing support offerings.

■Absorbing and Merging Open Source Utilization Research Institute, Integrating Structure

Magicemi's brand and services will continue as before, with Yuichi Terada remaining as Representative Director.

Furthermore, to further integrate the business operation structure after joining the group, accelerate decision-making, and improve value provision, an absorption-type merger was carried out on April 1, 2026, with Magicemi Co., Ltd. as the surviving company and Open Source Utilization Research Institute Co., Ltd. as the absorbed company.

Even after joining the ITmedia Group, there will be no changes to existing customer contracts or services provided.
