The female tech executives have worked to gain net worths reaching the hundreds of millions - and even billions.
Some of the most powerful people in Silicon Valley are industry veterans who have been steadily wading through the rankings since first coming to the scene in the early days of tech powerhouses like Google and Facebook - women like YouTube CEO

Wojcicki and Mayer are just two of the 23 women in tech who made
Forbes' 2019 list of richest self-made women in the US
