Blue Ocean X Holdings Co., Ltd. (Headquarters: 2-2-15 Hamamatsucho, Minato-ku, Tokyo, Representative: Satoshi Tanaka, hereinafter "our company") announces that our representative Satoshi Tanaka has assumed the position of Representative Director of Social Score Co., Ltd. (Headquarters: 5F EX Ebisu Nishi Bldg, 2-8-4 Ebisu Nishi, Shibuya-ku, Tokyo, hereinafter "Social Score") on March 1, 2026. This follows the successful sale of the company by Gentosha editor Kosuke Minowa at a corporate value of 100 million yen.
Mr. Minowa launched "Social Reach" as an experimental project to verify whether "a business can be polished from an initial investment of 10 million yen to achieve a market value of 100 million yen," and successfully achieved that goal. With this full sale of shares, Social Score has entered a new phase, transitioning from a "project" to a "continuously scaling business." Additionally, Ryotaro Ejima will continue to participate as an advisor, and Masahisa Saishiki has acquired 70% of the company's shares, supporting its growth strategy as the principal shareholder.
Through this transaction, our company will promote the business expansion of the sales and recruitment support platform "Social Reach" utilizing X (formerly Twitter) and strengthen collaboration with partner companies and agencies.
1. Background: Kosuke Minowa achieves sale going from "10 million yen to 100 million yen"
The "Social Reach" project started with a plan by Gentosha editor Kosuke Minowa. Mr. Minowa launched the service with an initial investment of 10 million yen, rapidly driving product development and market validation. As a result, he achieved the initial project goal of selling the business at a corporate value of 100 million yen.
With this complete sale of shares, Social Score has completed its validation phase and moves to a new stage as a continuously scaling business entity.
2. New Structure: Our representative Satoshi Tanaka appointed as Representative Director, Ryotaro Ejima supporting as advisor
To expand its business, Social Score welcomed our representative Satoshi Tanaka as Representative Director. Tanaka has experience in management and organizational operations across multiple businesses, with particular strength in expansion design through partner collaboration (agency design). In the past, he grew a business partnership with a TSE-listed company into the No. 1 group in agency sales performance, establishing multiple agency organizations of around 100 companies.
Furthermore, Ryotaro Ejima, who has led the ideology and product development of "Social Reach" since the project stage, participates as an advisor to support product strategy and business growth.
Moving forward, Social Score aims to increase its corporate value from 100 million yen to a market capitalization of 1 billion yen within three years, jointly promoting the strengthening of product value and the establishment of a sales structure.
3. Value Provided: A new model for corporate sales and recruitment, "reaching decision-makers directly" on X
While traditional corporate sales tend to center around phone calls, inquiry forms, and DMs, recent issues include declining response rates and difficulty in differentiation due to information overload and advancements in automation.
On the other hand, there is a growing trend of executives and decision-makers, including those at listed companies, using X to gather and disseminate information.
Given these changes, "Social Reach," provided by Social Score, supports a mechanism that starts from "building relationships" rather than "selling," allowing natural connections with decision-makers that lead to business meetings and recruitment.
