Overview
Rimini Street is the largest independent provider of third-party software support, founded in 2005 by Seth Ravin, who remains CEO and chairman. The firm is publicly listed on Nasdaq under the ticker RMNI and reported US$422 million in revenue for full-year 2025, with approximately 2,100 employees across 22 countries. Worldwide headquarters are in Las Vegas, Nevada, with regional delivery hubs in the United States, Europe, India, Israel, and Asia-Pacific. The core commercial proposition is replacing Oracle and SAP vendor support contracts at typically half the licence-fee maintenance cost while preserving service levels and removing the requirement to upgrade.
Rimini Street covers Oracle Database, Oracle E-Business Suite, PeopleSoft, JD Edwards EnterpriseOne and World, Siebel, Hyperion, and Oracle Retail, plus SAP ECC 6.0, S/4HANA, Business Suite 7, BusinessObjects, and SAP databases. The firm also supports Salesforce, IBM Db2 and middleware, Microsoft SQL Server and Windows Server, VMware, and a growing list of open-source databases under the Rimini Custodian umbrella. Additional services include Rimini Manage application managed services, Rimini Consult professional services, and Rimini Watch enterprise security monitoring. Rimini Street has a long-running legal history with Oracle, with several decided cases that have shaped the third-party support market.
Rimini Street is a fit for organisations running stable Oracle or SAP estates with limited need for new feature releases, where the buyer wants to reclaim maintenance budget and extend the life of the existing system rather than fund a forced upgrade. The firm is rarely the right choice for buyers planning an aggressive move to SAP S/4HANA Cloud or Oracle Fusion Cloud, because cutting OEM support typically severs upgrade rights and new-product entitlements. Buyers should pair a Rimini Street engagement with an independent licence advisor to validate the exit position.

Strengths
- Largest independent third-party support provider with a 20-year operating history and public-company disclosure
- Documented ~50% reduction versus OEM maintenance across Oracle and SAP support contracts
- 15-year support guarantee from contract inception, with no forced upgrade requirement
- Tax, legal, and regulatory update coverage delivered by in-house tax engineers across 200+ countries
- Strong global delivery footprint with named primary engineers per account and 10-minute response SLA on Priority 1 issues
Limitations
- Switching to Rimini Street terminates OEM support, which usually cuts access to new releases, patches, and upgrade rights — incompatible with active S/4HANA or Fusion Cloud migration plans
- Ongoing legal complexity with Oracle has created episodic uncertainty around scope, particularly for PeopleSoft and Siebel customers
- Not a fit for customers wanting OEM-aligned new feature deployment or net-new module purchases
- Reinstating OEM support after a Rimini Street period typically triggers back-maintenance fees and penalty charges
- Premium-priced versus smaller specialist third-party support firms such as Spinnaker Support on like-for-like scope
