Fullerene Inc. Appoints Yuki Mukasa as CTO

Fullerene Inc. (Headquarters: Minato-ku, Tokyo; Representatives: Takumi Yura, Takuma Sakamoto; hereinafter "the Company") is pleased to announce that Yuki Mukasa (Mukasa Yuki) has been appointed as Chief Technology Officer (CTO).

The Company's mission is to "structure top-tier professional services through the power of technology, thereby realizing corporate value enhancement where business, capital, and organization are interconnected." To this end, we support critical business decisions and execution by providing services that span strategic consulting, M&A advisory, recruitment, and AI enablement.

In recent years, with the evolution of technologies such as generative AI, the landscape of high-level professional services including corporate planning, M&A, and human capital/organizational transformation has reached a major turning point. Since its inception, the Company has viewed AI not merely as a tool for operational efficiency, but as a foundation for enhancing the accuracy of judgments and execution that should be handled by human intellect, and has been working to build an AI-native business infrastructure.

Background of CTO Appointment

Currently, the Company is focused on reflecting the knowledge gained from high-difficulty projects by professionals and the actions of highly-rated advisors into an AI-native operational infrastructure, with the generative AI platform "FULLERENE HUB" at its core. In the M&A domain, we are achieving automation of matching and sophistication of deal management through AI-powered market/competitor analysis, long list creation, extraction of past similar deals, synergy verification, approach automation, and DD automation. Furthermore, by connecting M&A Hub (CRM/SFA), Data Foundation, and Output Factory, we aim to realize an "AI Deal Workforce" in the future, where AI agents will support deal progression, suggest next actions, and assist with document generation and updates.

In the human capital domain, we are also advancing the use of AI by creating databases of candidate pools, primarily in the finance and consulting sectors, and information on both client companies and candidates. This enables us to enhance customer management, accurately match candidates with job openings, improve the precision of process design, and increase the efficiency of agent operations.

It is a fundamental prerequisite that valuable information entrusted to us by clients is handled appropriately in accordance with laws and regulations.

Mukasa has led system development in the SaaS, data infrastructure, and payment domains for over 10 years as a software engineer. As a freelancer, he spearheaded the launch of multiple SaaS products, consistently handling everything from requirements definition to design, implementation, operation, and the establishment of development organizations. Subsequently, at Mercari/Merpay, he served as a software engineer and tech lead, driving the company-wide deployment of the corporate account infrastructure and the design and operation of payment and account infrastructure for tens of millions of users. He joined our company in November 2025 and has been leading the development of AI products and internal/external AI utilization platforms.

Moving forward, as CTO, Mukasa will drive the development of a technological foundation that structures the knowledge and operational processes accumulated in strategic consulting, M&A, and human capital domains through AI and software, contributing not only to internal productivity improvements but also to strengthening the corporate planning, M&A, human capital, and organizational functions of client companies.

With this CTO appointment, the Company will further accelerate the implementation of technology towards the democratization of professional services.

Comment from CTO Yuki Mukasa

At our company, professionals engage in high-level decision-making and execution daily across multiple business areas: strategic consulting, M&A, and recruitment. On the other hand, there remains significant room for improvement in these fields through AI and software, enabling us to tackle various challenges faster, deeper, and with greater reproducibility.

What I aim to achieve as CTO is not mere operational efficiency. It is to implement the techniques and expertise of each professional, and the knowledge cultivated in the field, as the company's infrastructure, and to enhance the value provided through the collaboration of humans and AI.

In the M&A domain, we will establish a platform that can centrally manage information such as deal details, buyer needs, seller information, contact and activity history, dialogue logs, and matching candidates, allowing advisors to focus more on essential issue design, negotiation, and decision support. In the human capital domain, by structuring candidate, client, job opening, and contact history, we aim to achieve both advanced customer management and efficient agent operations, thereby realizing accurate matching without omissions and higher quality career support.

AI is an extremely powerful technology, but I believe it can only lead to intrinsic value when provided with correct domain knowledge and contextual understanding of the field, and when humans maintain control. We will embody our company's philosophy of "Work diligently, refine with intellect" as a technological foundation and contribute to the realization of top-tier management support infrastructure accessible to everyone.

Comment from CEO Takumi Yura

Since our founding, our company has been leveraging technology, including AI, to enhance the value of judgments and execution performed by humans in the fields of M&A and management support.

Mukasa possesses not only high technical skills as a software engineer but also the ability to deeply understand business-side operations and field context. He is an extremely important figure in overcoming the typical disconnect between technology and professional services and creating new added value as One Team.

With this CTO appointment, our company will further accelerate the development of AI products and our AI enablement business. We will advance the automation of matching and sophistication of deal management in the M&A domain, and the enhancement of customer management and efficiency of agent operations in the human capital domain, thereby supporting client companies' decision-making and execution at a higher level.
