Oracle, co-founded in 1977 by Ellison, Bob Miner, and Ed Oates, first rose to prominence with its database software, originally inspired by a CIA project.
By 1987, it had become the global leader in database management systems.
Over the years, Oracle expanded aggressively through acquisitions, including PeopleSoft, Sun Microsystems, and NetSuite.
More recently, the company pivoted toward cloud computing and AI infrastructure, running massive data centers that supply computing power and storage to leading firms.
This transformation has paid off in the AI era. Companies such as OpenAI, the creator of ChatGPT, depend on Oracle’s cloud systems to train and deploy advanced AI models.

Although Ellison stepped down as CEO in 2014, he continues to shape Oracle’s future as executive chairman and chief technology officer.
In 2025, he spearheaded the $500 billion “Stargate” project, an ambitious initiative to build AI-focused data centers, strengthening Oracle’s place in the global tech ecosystem.
