KleanNara Partners with Rimini Street to Accelerate Digital Transformation

South Korea’s leading paper manufacturer cuts SAP ECC and Oracle Database maintenance costs with Rimini Support™, freeing up funds and team focus for AI-driven innovation and growth

LAS VEGAS – February 25, 2026 –Rimini Street, Inc. (Nasdaq: RMNI), the Software Support and Agentic AI ERP Company™, and the leading third-party support provider for Oracle, SAP and VMware software, today announced KleanNara has selected Rimini Street to provide support for its SAP ECC 6 and Oracle Database systems.

Founded in 1966, KleanNara is one of South Korea’s leading manufacturers of paper and hygiene products. Holding a 25% share of the white cardboard market, the company is known for its commitment to quality, sustainability and innovation, and continues to expand globally with a focus on ESG-driven, eco-friendly products.

Breaking Free from Traditional ERP Support Constraints

For years, KleanNara relied on a traditional ERP support model for its SAP ECC 6 and Oracle Database, systems which are critical for the company’s finance, accounting, sales and customer data management. As the company expanded, IT operations faced high support costs, unresponsive and low-value support services and forced software upgrades just to maintain vendor support.

“To accelerate digital transformation and to remain competitive in a rapidly changing market environment, it was imperative to increase the flexibility and efficiency of our IT systems,” said Hongjun Jang, digital experience manager at KleanNara. “We needed to keep current systems stable while adopting new technologies and establishing a business-driven roadmap.”

Rimini Support™ Brings Stability, Flexibility and Significant Cost Savings

KleanNara needed an ERP support model that could dramatically cut costs, deliver faster, more reliable service and free up people, time and money for growth projects such as AI, cloud strategy and leveraging Internet of Things (IoT) to optimize operations. The company chose Rimini Street for its strong reputation in the industry and ability to provide expert, responsive service with transparent, structured SLAs and a client-focused service model.

KleanNara achieved immediate financial benefits with Rimini Support™ for SAP and Rimini Support™ for Oracle. By consolidating support under one trusted partner, KleanNara reduced annual vendor support fees by 50% and achieved major improvements in support responsiveness.

“Rimini Street is quick and accurate, especially when working with customized code and complex systems,” Jang said. “Issues that would have taken days to resolve with a traditional vendor are often resolved within hours with Rimini Street.”

Investing in AI-Driven Innovation to Support Growth

With the savings and time KleanNara regained by switching from vendor support to Rimini Street, the company accelerated several key initiatives, including building an AI-powered analytics platform, expanding cloud footprint and implementing IoT in production. These efforts enable the company to forecast and respond to market demand, reduce production costs and maximize inventory efficiency. The savings also support talent recruitment and development to further KleanNara’s digital transformation vision.

“Reducing fixed costs and optimizing IT operating expenses has paved the way to reinvest resources in core business objectives, including digital transformation, developing eco-friendly products and streamlining production processes, which have been instrumental in strengthening the company’s competitiveness and supporting sustainable growth,” Jang said. “Stabilizing our core systems created space to innovate. Rimini Street has become a key partner in helping us modernize while maintaining the reliability we need.”

“Mandatory migrations and frequent upgrade cycles often expose organizations to unnecessary risks, unexpected costs and operational disruptions — threatening business continuity and slowing innovation,” said Hyungwook Kim, GVP and Regional GM, Rimini Street Korea. “We’re proud to be KleanNara’s partner and help them break free from these constraints, empowering their IT teams to focus on priority initiatives and drive measurable business outcomes. Rimini Street delivers the stability, flexibility and expert guidance needed to support and accelerate KleanNara’s ambitious growth and digital transformation goals.”
