S.S.B., a leading developer of receipt computer systems for chiropractic and orthopedic clinics with the largest market share in Japan, has joined the industry-specialized software group SIVA Group. This integration will accelerate business optimization and AI-driven service innovation.

SIVA Co., Ltd. (Headquarters: Minato-ku, Tokyo; CEO: Toshiyuki Sugiura; hereinafter "SIVA Group"), an industry-specialized software group, announces that S.S.B. Co., Ltd. (Headquarters: Tsukuba, Ibaraki; President: Keisho Oshiro; hereinafter "S.S.B."), a leading developer and provider of receipt computers ("rececons") for chiropractic and orthopedic clinics, has joined the SIVA Group.

This marks the fifth M&A transaction for SIVA Group, following acquisitions of Squad Co., Ltd., VERTICE Co., Ltd., Business Brain Co., Ltd., and Media Link-i Co., Ltd., and represents the group’s first capital alliance with a healthcare software company.

◆ Background of S.S.B.'s Integration into the Group

Since its founding in 1977, S.S.B. has been a leading company in the rececon market for chiropractic and orthopedic clinics, securing the top domestic market share. In addition to developing and selling rececon software, S.S.B. provides host computer systems for judo orthopedic associations and sells medical devices such as ultrasound diagnostic equipment, demonstrating deep domain expertise and high customer retention in the healthcare sector.

While S.S.B. boasts strong market share and a stable customer base, there remains significant potential for growth through advanced management practices, enhanced digital marketing, and AI-powered new service development. SIVA Group, leveraging its investment experience in the IT/software sector through JGIA and advanced management practices cultivated across its portfolio companies, is confident that it can support S.S.B.’s current management team in maintaining operations while strongly accelerating future growth—leading to this strategic integration.

◆ Value Proposition to Customers (Clinics and Judo Orthopedic Associations)

Through this integration, SIVA Group will leverage its managerial and technological assets to accelerate the following value propositions:

Advanced Management Practices: Implementation of SIVA Group’s PMI methodologies and advanced management case studies to improve productivity and profitability.

Enhanced Digital Marketing: Strengthening customer acquisition and engagement through online channels, expanding the business foundation.

AI-Powered New Service Development: Developing new AI-driven services to automate and streamline clinic operations, starting with rececon workflows.

◆ Company Overview: SIVA Co., Ltd.

SIVA Group is a vertical software holding company where outstanding vertical software firms come together, mutually enhancing each other to achieve non-linear growth. While preserving the strengths of acquired companies, SIVA conducts equitable post-merger integration (PMI), strengthening management foundations, new business development, and talent cultivation. The group amplifies growth opportunities and reinvests generated cash flows into further expansion.

Recognizing that many high-quality Japanese software companies in niche markets, despite strong market share and profitability, face growth plateaus due to succession issues and slow digitalization, SIVA Group officially launched in October 2024 and has since secured over 10 billion JPY in funding. Currently, five companies are part of the group: Squad Co., Ltd., VERTICE Co., Ltd., Business Brain Co., Ltd., Media Link-i Co., Ltd., and S.S.B. Co., Ltd. Through its proprietary PMI methodology, SIVA enables digital transformation and improved profitability across all group companies, offering operational and technological empowerment beyond mere capital investment.

SIVA Group aims to build this unprecedented growth model into a globally recognized success story.
