Business

Prime Strategy Co., Ltd. originated in 2002 as a WordPress-specialized system integrator and, since 2015, has built its business around its proprietary ultra-high-speed CMS execution environment "KUSANAGI." The company provides "KUSANAGI Stack," composed of "KUSANAGI," "WEXAL® Page Speed Technology®," and "ONIMARU® David," on public cloud platforms, offering corporate clients end-to-end support for website acceleration, maintenance, and operation. Its main customers are corporations operating medium- to large-scale websites, including major companies such as Sumitomo Realty & Development. In December 2025, the company became a subsidiary of GMO Internet Group, Inc., entering a new growth phase.

Business Model

The free version of "KUSANAGI" has achieved broad recognition (cumulative operational units exceeding 100,000, spanning 218 regions across 39 countries), and revenue is generated through three paid services: KUSANAGI Managed Service byGMO (monthly subscription), Cloud Integration Service (spot-type SI), and license sales (via cloud marketplaces). In the sales composition for FY2025 (ending November 2025), Managed Service accounted for ¥599 million (67.5%), license sales for ¥160 million (18.1%), and Cloud Integration for ¥128 million (14.4%).

Company Strengths

As of end-June 2025, KUSANAGI's cumulative number of active instances exceeded 100,000, with direct partnerships established with 26 domestic and overseas cloud providers. It is available in 218 regions across 39 countries, and its widespread adoption through the freemium model serves as a powerful funnel toward paid services.

KUSANAGI accelerates not only the application layer but also server-side processing such as PHP and databases, achieving approximately 260x faster performance compared to a standard environment when page caching is used, and approximately 1.8x faster even without caching. Its technical approach is fundamentally different from that of competing WordPress acceleration plugins.

At the end of FY2025 (ending November 2025), the equity ratio stood at 88.5% (up from 86.3% in the previous period), with cash and cash equivalents of ¥1,284 million. Following the full repayment of long-term borrowings, interest-bearing debt has fallen to effectively zero, maintaining a level of financial soundness close to a debt-free management structure.

ENVALITH's Perspective

In the interim period of FY2026 (ending December 2026), revenue increased to ¥470 million (up 8.7% year on year), but profits declined across all stages compared to the same period last year: operating profit was ¥63 million (down 8.1%), ordinary profit was ¥64 million (down 6.7%), and interim net profit was ¥47 million (down 2.5%). Cost of sales increased simultaneously (from ¥189 million to ¥216 million) alongside expansion in SG&A expenses (from ¥174 million to ¥190 million), and the trend of deteriorating annual profits seen over the past four fiscal years has continued into this interim period, remaining a structural concern.

Joining the GMO Internet Group and launching the AI business (AI Automated Grading Solution / GMO AI RAG) could serve as a turning point for mid- to long-term business expansion. There is also a favorable external environment, with growing corporate investment in digitalization and generative AI adoption. However, in this interim period, the AI business was judged to lack materiality, and segment disclosure was omitted, meaning its contribution to short-term performance is limited. Continued monitoring of concrete progress in realizing synergies will be necessary.

The full-year forecast for FY2026 (ending December 2026, a 13-month fiscal period) remains unchanged, with revenue of ¥1,124 million, operating profit of ¥70 million, ordinary profit of ¥72 million, and net profit of ¥51 million. Given that interim operating profit was ¥63 million against a full-year forecast of ¥70 million, this implies a plan for only ¥7 million in additional profit accumulation during the second half (the seven months from June to December), reflecting a conservative structure premised on increased costs and continued investment in the second half. It should also be noted that comparison with the previous period is difficult due to the 13-month fiscal period resulting from the change in fiscal year-end.

Growth Strategy

Aiming for growth along three axes: leveraging GMO Group synergies, developing new AI businesses, and expanding managed services

The company is implementing a combination of personnel expansion, sales capability strengthening, and marketing initiatives to drive new customer acquisition for its end-to-end website maintenance and operation service. Revenue from managed service operations was noted as strong in the current interim period, making it a key driver of revenue growth.

Group joining was completed on December 26, 2025. By leveraging GMO Group's customer base, technology, and brand, the company aims to simultaneously strengthen clients' digital infrastructure and improve operational efficiency through AI utilization, thereby enhancing medium- to long-term corporate value. Reflecting concrete synergy effects in financial results remains a future challenge.

Starting in the current interim period, the company began providing the AI Automated Grading Solution and released GMO AI RAG. A new "AI Business" segment was established, but as it currently lacks materiality, segment disclosure is being omitted for now. The company aims to nurture this business, riding the tailwind of expanding market investment in generative AI utilization.

The company is pursuing marketing and product capability enhancements in parallel, aiming to expand sales of the paid license. Since improving the conversion rate from the freemium model to paid subscriptions is directly linked to profitability improvement, continued efforts are required.
