Part I — The story
The story
Larry Ellison built Oracle into a software giant by dominating something most consumers never see but every large organisation depends on: the relational database that stores their critical data. Once a company's operations run on your database, ripping it out is enormously risky and expensive — a switching cost Ellison understood and exploited for decades.
Brash, competitive, and famously combative, Ellison co-founded Oracle in 1977 after reading a paper on relational databases that IBM had underestimated commercially. He moved faster than incumbents to market, then expanded through relentless sales and a long series of acquisitions that widened Oracle's grip on enterprise IT.
Ellison's later years saw Oracle pivot toward cloud computing, competing with younger rivals, and Ellison himself become one of the world's wealthiest people. His edge was never elegance; it was understanding that mission-critical infrastructure, once installed, is extraordinarily sticky.
Part II — The playbook
The playbook
Own the mission-critical layer
Ellison built on the database — unglamorous but indispensable — because losing it would cripple a customer's operations.
Exploit switching costs
Migrating a company's core data off Oracle is risky and costly, giving enormous pricing power.
Grow by acquisition
Oracle bought its way into new markets and absorbed rivals, widening the moat.
In their words
When you innovate, you've got to be prepared for everyone telling you you're nuts.
The only way to get ahead is to find errors in conventional wisdom.

Frequently asked questions
Why is Oracle so entrenched in big companies?
Because its databases store mission-critical data, and migrating off them is risky and expensive — a powerful switching cost that gives Oracle durable pricing power.
What is Larry Ellison's role now?
He stepped down as CEO in 2014 and serves as Oracle's chairman and chief technology officer.
