PathosLogos Inc. (Headquarters: Shinagawa-ku, Tokyo; Representative Director and CEO: Masayuki Makino; hereinafter referred to as "the Company") completed a third-party allocation of new shares totaling approximately 1.6 billion yen at the end of March 2026, with funds managed by SBI Investment Co., Ltd. and Rheos Capital Partners Co., Ltd., as lead investors in its Series B funding round. Including the conversion of J-KISS (approximately 1.5 billion yen) from existing shareholders implemented in May 2025, the total amount raised in Series B reaches 3.1 billion yen. This brings the Company's cumulative total funding to 6.8 billion yen.
The Company has been selling its HR co-creation platform "PathosLogos," a SaaS for integrated HR databases that allows for flexible combination of optimally specialized HR SaaS, along with "Combosite HR Payroll," an HR and payroll SaaS tailored for large enterprises, since April 2023. It has already been adopted by over 100 groups and 300 companies.
The funds raised in this round will primarily be invested in the following key areas:
* **Expansion of AI products for the HR co-creation platform "PathosLogos"**
* A beta version of the AI product "PathosLogos Chatbot," which utilizes data accumulated in the integrated HR database to provide personalized answers to employee inquiries, was released in February 2026 (*1). The Company plans to develop other AI agents for various HR domains, aiming to free HR personnel from routine tasks and support their shift to more strategic work.
* **Further functional enhancement of "Combosite HR Payroll"**
* Continued investment in development will enable more flexible and efficient operation of HR systems for large enterprises, which tend to become complex and unwieldy.
**Comments from Investors and Our Representative**
* **Mr. Kyota Suzuki, Deputy General Manager, Investment Department, SBI Investment Co., Ltd., and Mr. Hikaru Hagiwara, Investment Department**
"We are deeply honored to have participated as lead investors in this round.
Mr. Makino, who leads PathosLogos, is a pioneer who spearheaded the proliferation of the first domestic ERP for large enterprises in Japan. This new venture is also based on a high aspiration to 'catch up on the digital shift in Japan's HR domain.' The HR co-creation platform 'PathosLogos' offered by the Company is not just an efficiency tool; it possesses the potential to become an indispensable social infrastructure in the age of AI.
As lead investors, we will fully support the Company's growth and social implementation, including its utilization within the SBI Group, and expect it to leap forward as an entity that rewrites Japan's HR infrastructure."
* **Mr. Hidetoshi Fujino, President and CEO, Rheos Capital Partners Co., Ltd.**
"My relationship with President Makino spans over 20 years, and what I realize anew is that an excellent business leader is not merely someone who creates products, but someone who evolves the very structure of an industry. His journey of developing a domestic HR ERP for large enterprises and nurturing it into a de facto standard in the Japanese market was truly an endeavor that transcended the success of a single company, bringing new order to the HR domain in Japan. The current initiative by PathosLogos, undertaken by Mr. Makino, strongly conveys an intention for structural transformation on a higher dimension, not just an extension of previous efforts.
This time, we decided to invest through 'Hifumi Crossover Pro,' which provides long-term support to companies before and after listing. This investment is not a gamble on a short-term growth story. Rather, it is a decision based on our belief that PathosLogos will pass through its IPO as a milestone and continue to provide value to society for 10, 20 years as a foundation supporting Japan's HR infrastructure. We have high expectations and are fully committed to providing support."
* **Masayuki Makino, Representative Director and CEO, PathosLogos Inc.**
"We would like to express our sincere gratitude to everyone who supported us in this funding round. Through our HR co-creation platform 'PathosLogos' and 'Combosite HR Payroll,' we provide a foundation that standardizes and links HR data held individually by each SaaS for collaborative utilization. As AI utilization becomes a prerequisite for productivity improvement, the importance of standardizing and centralizing HR data is growing ever higher. Leveraging this fundraising, we will further strengthen our development system, customer support system, and collaborations with co-creation partners, accelerating initiatives to support HR transformation in Japanese companies."
