The five biggest companies in the US by revenue or profit are not data-driven tech companies.

None of the top ten US companies, by revenue, fit that description.

Ranked by profit, only Alphabet squeaks into the top ten at number five.

I’m not seeing much correlation here between rank of CEO compensation and company performance.

The fame of the high salaries at tech companies relates primarily to technical staff, not executive pay. These companies are also located in some of the most expensive areas to live.
