ITmedia Strengthens B2B Marketing Support by Welcoming Majisemi Co., Ltd. to its Group

ITmedia Inc. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Noriyoshi Kobayashi; hereinafter referred to as "our company") announced today, April 1, 2026, that it has completed the acquisition of all shares of Majisemi Co., Ltd. (hereinafter referred to as "Majisemi"), as announced on January 29, 2026, in "ITmedia Acquires All Shares of Majisemi Co., Ltd. and Makes it a Subsidiary." Through the subsidiary integration of Majisemi, we will link the membership bases and services of both companies to more powerfully support customers in acquiring leads (potential customers) for their marketing activities.

Background

Majisemi is a B2B marketing support company that provides leads to companies through over 1,000 webinars annually. With over 200,000 members, it offers "serious problem-solving seminars that provide truly useful information for participants," primarily in the technology domain. Furthermore, under the keyword "Webinar as a Service," it provides a subscription-based service that offers one-stop support from customer acquisition to planning and day-of operations for companies holding webinars, serving over 200 client companies annually, mainly IT firms. On the other hand, our company, as one of Japan's largest specialized technology media outlets, has a membership base of approximately 2 million individuals and has hosted a variety of digital events, from large-scale virtual exhibitions to webinars. Both companies share a common philosophy: "To contribute to society by disseminating the correct utilization methods of technology through highly specialized information provision." Based on this philosophy, we determined that by combining our respective strengths, we could further contribute to our customers' business growth, leading to this subsidiary integration.

Objective

The greatest objective of this matter is to strengthen lead provision capabilities to customers by fusing the media and event infrastructure, personnel, and service know-how held by both companies. By combining our company's strength in "premium, large-scale, and multi-faceted digital events" with Majisemi's expertise in "easy and high-frequency webinar operation agency services," we will be able to offer optimal solutions tailored to any budget or marketing challenge, from startups and small to medium-sized enterprises to large corporations.

Future Outlook

Going forward, we will create the following synergistic effects and provide new value to our corporate clients:

・ Realization of "Overwhelming Customer Acquisition Power" by utilizing membership bases with different acquisition channels

Majisemi's over 200,000 members, acquired through channels distinct from ours, such as exhibition participation, will be added to our approximately 2 million member base. By linking these resources, we will significantly enhance the customer acquisition power and reach for client webinars and events.

・ Response to Diverse Marketing Needs through Mutual Collaboration

We will create an environment where both companies can sell each other's offerings, such as proposing Majisemi's services to our clients and our media products to Majisemi's clients, thereby expanding the scope of proposals to customers. We also plan to promote the development of proprietary services leveraging the advanced data of both companies.

ITmedia and Majisemi will work together as a group to expand the share of lead provision services through digital events and further contribute to solving challenges in B2B marketing.

Comment from Noriyoshi Kobayashi, President and CEO, ITmedia Inc.

"ITmedia's mission is to 'Achieve an information revolution and contribute to society through media innovation.' We are extremely pleased to welcome Majisemi to our group, a company that hosts over 1,000 webinars annually and supports customer lead acquisition through 'Webinar as a Service.' Under our shared philosophy of spreading the correct utilization methods of technology and contributing to society, ITmedia's approximately 2 million member base and track record in operating large-scale digital events will merge with Majisemi's agile webinar operation know-how. This will establish a system capable of responding to all customer marketing needs and overwhelmingly supporting lead acquisition activities.

Furthermore, going forward, we plan to combine both companies' know-how and data to develop new value through AI utilization, and to deploy unique joint products that meet more advanced needs. Please look forward to the new value that the ITmedia group will provide to solve customer challenges and drive business growth in B2B marketing."

Comment from Yuichi Terada, Representative Director, Majisemi Co., Ltd.

"I am very pleased to be able to start a new chapter as a member of the ITmedia group.

Majisemi has supported corporate lead acquisition through over 1,000 webinars annually. With the addition of ITmedia's approximately 2 million member base and media operation capabilities, we believe we can support corporate B2B marketing activities more powerfully than ever before.

Amidst the significant changes in corporate information gathering and marketing due to the spread of generative AI, webinars have become an important communication channel for direct connection between companies and customers. Going forward, we will collaborate with the ITmedia group to provide services that can contribute to the business growth of more companies."
