Blue Ocean X Holdings Inc. (Headquarters: 2-2-15 Hamamatsucho, Minato-ku, Tokyo; Representative: Tomokazu Tanaka; hereinafter 'Our Company') is pleased to announce that Tomokazu Tanaka, our representative, has been appointed Representative Director of the company **Social Score Inc.** (Headquarters: EX Ebisu-Nishi Building 5F, 2-8-4 Ebisu-Nishi, Shibuya-ku, Tokyo; hereinafter 'Social Score'), which was sold by Gentosha editor Kousuke Minowa for a corporate value of 100 million yen (Appointment Date: 【March 1, 2026】).

Mr. Minowa launched "Social Reach" as a verification project to answer the question, 'Can a business be refined with an initial investment of 10 million yen and sold for a market price of 100 million yen?' and achieved its goal. With the complete sale of shares this time, Social Score Inc. has entered a new phase, transitioning from a 'project' to a 'continuously scalable business.' Additionally, Ryotaro Ejima will continue to participate as an advisor, and Sachihisa Saishiki has acquired 70% of the company's shares to become the principal shareholder, supporting its growth strategy.

Through this initiative, Our Company will promote the business expansion of "Social Reach," a platform for sales and recruitment support utilizing X (formerly Twitter), and strengthen cooperation with partner companies and agencies.

**1. Background: Kousuke Minowa Achieves Sale from '10 Million Yen to 100 Million Yen'**

The "Social Reach" project was launched based on a plan by Gentosha editor Kousuke Minowa. Mr. Minowa launched the service with an initial investment of 10 million yen, rapidly advancing product development and market verification. As a result, he achieved the project's initial goal of selling for a corporate value of 100 million yen.

With the sale of all shares, Social Score Inc. has completed its verification phase and is moving into a new stage as a continuously scalable business entity.

**2. New Structure: Our Representative Tomokazu Tanaka Appointed Representative Director, Ryotaro Ejima to Support as Advisor**

To expand its business, Social Score Inc. has welcomed Our Company's representative, Tomokazu Tanaka, as its Representative Director. Mr. Tanaka possesses extensive experience in management and organizational operations across multiple businesses, with particular strengths in expansion design through partner collaboration (agency design). In the past, he grew business alliances with publicly traded companies on the Tokyo Stock Exchange into the No. 1 group in agency sales performance and has built multiple agency organizations of the '100-company class.'

Furthermore, Ryotaro Ejima, who has led the ideology and product development of "Social Reach" since the project stage, will participate as an advisor to support product strategy and business growth.

Social Score Inc. will now drive product value enhancement and sales system construction in an integrated manner, aiming to increase its corporate value from 100 million yen to a market capitalization scale of 1 billion yen within three years.

**3. Value Proposition: A New Paradigm for Corporate Sales and Recruitment – 'Direct Reach to Decision-Makers' via X**

While traditional corporate sales often center around phone calls, forms, and direct mail, recent years have seen challenges such as declining response rates and difficulty in differentiation due to information overload and advancements in automation.

Meanwhile, an increasing number of executives and decision-makers, including those from listed companies, are utilizing X for information gathering and dissemination.

"Social Reach," provided by Social Score Inc., is built on this changing landscape. It supports mechanisms for naturally connecting with decision-makers and leading to business meetings and hiring, starting from 'relationship building' rather than 'sales pitches.'

**4. Key Features of 'Social Reach'**

**(1) AI Assists Engagement, Significantly Reducing Operational Load**
AI supports daily engagement activities (likes, reposts, quotes, etc.), reducing operational burden (e.g., estimated operational time: '1 hour/day → 10 minutes').

**(2) AI Proposes 'Appropriate Contacts' and 'Appropriate Approaches'**
Based on company information and objectives (sales/recruitment), it suggests priority contacts and action plans, enhancing the precision of relationship building.

**(3) Realizes Team Operation with Authority Management, Safely Making SNS an 'Organizational Asset'**
Enables operation by multiple people by granting permissions while avoiding ID/password sharing (e.g., HR handles contact building, executives respond to important DMs).

**5. Partner Collaboration: Fully Launching an Expansion Model Starting with Referrals**
Social Score Inc. will strengthen cooperation with partner companies and agencies to expand implementation and operational support nationwide.

To facilitate partner engagement, we emphasize a 'design that can be completed solely through referrals,' and will establish a system where the headquarters handles closing and after-sales follow-up.

**Tomokazu Tanaka, Representative of Blue Ocean X Holdings Inc. / Representative Director of Social Score Inc.**
'The era where 'relationship building,' not 'sales pitches,' determines success in corporate sales and recruitment is here.

We will fully utilize the agency design know-how and AI expertise cultivated by our group, advancing both product evolution and partner collaboration to aim for a market capitalization of 1 billion yen within three years.'
