For businesses, it provides the no-code cloud database "JUST.DB," the sales support tool "JUST.SFA," the BI solution "Actionista!," and the learning cloud service for the education market "Just Smile," among others.

With natural language processing, knowledge processing, and search technology as its core technologies, the company centers its value proposition on improving individuals' lives and enhancing corporate productivity and competitiveness.
Business Model
Subscription-based stock business accounts for 71.4% of net sales (¥36,776 million), forming a stable revenue base through reduced churn rates. For individuals, this centers on monthly-billed correspondence education and cloud services, while for corporate clients it centers on SaaS-type cloud solutions. Leveraging a financial foundation of zero interest-bearing debt and an equity ratio of 87.0%, the company maintains a high-profitability, high-cash-generation model that funds software development investment (¥2,954 million in intangible fixed asset acquisitions) from internal funds.
Company Strengths
In FY2026 (ending March 2026), subscription-type stock business net sales were ¥36,776 million (up 10.4% year on year), accounting for 71.4% of total company net sales. The recurring revenue model enhances revenue stability and predictability, achieving an earnings structure that is less susceptible to economic fluctuations.
As of the end of FY2026 (ending March 2026), interest-bearing debt was zero, cash and cash equivalents stood at ¥64,901 million, and the equity ratio was 87.0%. Operating cash flow generated ¥19,626 million, giving the company the financial flexibility to actively pursue development investment and M&A without relying on external fundraising.
The company offers products for both individual customers (Smile Zemi, ATOK Passport, Ichitaro, etc.) and corporate customers (JUST.DB, JUST.SFA, Actionista!, JUST Smile, etc.), diversifying reliance on any specific customer segment. In FY2026 (ending March 2026), the company achieved growth on both fronts, with net sales of ¥33,173 million from individual customers and ¥18,342 million from corporate customers.
ENVALITH's Perspective
Performance Trend
Net sales over the past five fiscal years progressed as follows: FY2022 ¥41,676 million → FY2023 ¥41,950 million → FY2024 ¥40,985 million (a temporary dip) → FY2025 ¥44,551 million → FY2026 ¥51,515 million, entering a clearly accelerating phase following the adjustment in FY2024. Operating profit also expanded from ¥17,166 million in FY2022 to ¥22,492 million in FY2026, with the operating profit margin reaching 43.7%. In FY2026 (ending March 2026), the key drivers were strong growth in the corporate business (up 34.8% year on year) and the accumulation of stock-type business revenue (¥36,776 million). As an external tailwind, growing corporate demand for DX investment provided support. Operating cash flow improved substantially to ¥19,626 million (from ¥15,022 million in the previous period), and cash and cash equivalents at period-end stood at ¥64,901 million.
Growth Strategy
Continued increases in revenue and profit driven by AI integration, capture of corporate DX demand, and expansion of the stock (subscription) business
Introducing the AI feature "Coachez" into the individual-focused correspondence education service "Smile Zemi" to enhance learning outcomes and improve customer satisfaction. The company is also expanding the range of grade levels offered in its U.S. service to broaden its customer base in overseas markets. This initiative is positioned as a measure to sustain and accelerate the 7.2% year-on-year growth achieved in the individual-focused business.
Integrating generative AI into the no-code DX tool "JUST.DB" to capture corporate demand for DX promotion. The corporate business achieved ¥18,342 million in FY2026 (ending March 2026), up 34.8% year on year, and the company aims to further accelerate growth by enhancing added value through AI integration.
Expanding subscription-based stock business revenue and maintaining/improving its share of total company revenue (71.4% in FY2026, ending March 2026). Stock business revenue reached ¥36,776 million in FY2026 (ending March 2026), up 10.4% year on year, and the company will continue to strengthen its stable revenue base.
Placing emphasis on the continuous growth of "operating profit per employee" as a key management indicator, balancing improved customer satisfaction through enhanced functionality of existing products with expansion of the customer base through development of new products and services. The operating profit margin of 43.7% in FY2026 (ending March 2026) (up from 40.5% in the previous fiscal year) reflects the results of this policy.
