It's no secret tech leaders wield a large influence when ranking the world's richest people.
Eight of the top 20 billionaires in the world earned their wealth through the tech sector, according to Bloomberg's billionaires index.
Of those tech billionaires, seven are among the top 10 richest overall.
The tech billionaires on the list earned their fortunes through industries including automotive, online retail, software and social media. The top seven tech entrepreneurs have a combined net worth topping $936 billion.
But they've also lost plenty of cash compared to this time a year ago.
According to Bloomberg, the combined net worth of the eight tech billionaires in the top 20 plunged by $256 billion, roughly equal to the gross domestic product of New Zealand, based on World Bank data.
