These eleven women who are holding the bull by the horn and making their mark in the tech business, are someone to look up to. They have also entered in the Forbes’ third annual Richest Self-Made Women list. All these women have one thing in common: the tact, grit, perseverance and the passion to attain such great heights in the Tech sector. Amongst the group: three are billionaires, five founded their own companies and seven are CEOs.

HP Enterprise CEO Meg Whitman, who is the proud owner of a fortune of $2.5 billion is the first in our list of successful women in the world of Tech. In August 2016, Whitman, endorsed Hillary Clinton and called Donald Trump a “demagogue.” She also went ahead and told an audience at the World Economic Forum in Davos that America needed to give Trump the benefit of doubt.

The mass amount of Whitman’s fortune came from her term at eBay as a CEO. The revenue of the company grew from $5.7 million to $8 billion, under her compelling decade long leadership. Before being a CEO in eBay, Whitman was an executive at Walt Disney and Hasbro. She is thus, the richest self-made woman in USA.

Facebook Chief Operating office Sheryl Sandberg and SHI International CEO Thai Lee, each have a $1.6 billion of fortune. Lee, lives in New Jersey and also runs IT provider SHI International which had $7.6 billion in 2016 sales record. These passionate and uber rich women in tech are the epitome of overriding passion, red-hot ambitions and straightly structured visions which made them hit the golden pot. Sandberg, this woman became the Silicon Valley poster child of the fight for gender equality in a workplace atmosphere after her 2013 book ‘Lean In’. Sandberg has been the COO of Facebook since 2008 and has given in her best efforts in increasing the revenue of the tech giant.

In April, Sandberg published her second book, Option B, which was written after the untimely death of her husband, Dave Goldberg, in 2015. This book brings the points about resilience and grief forward.

YouTube CEO Susan Wojcicki, who has an approx of $410 million fortune, published a Vanity Fair op-ed called “How to Break Up the Silicon Valley Boy’s Club,” whereby she discussed sexism in Tech business and also the needful steps which the companies should take to support women. Since Wojcicki became the CEO, the ratio of women in business has increased from 24% to 30%.

Wojcicki, Sandberg and Yahoo CEO Marissa Mayer all worked in unison at Google, early in their careers. Mayer left Google to join Yahoo in 2012. Unfortunately, Mayer will be leaving the CEO position at Yahoo, after Yahoo is sold to Verizon for $4.48 billion. She has made a fortune of $540 million, the major portion of which she had made at her term in Google.

Oracle co-CEO Safra Catz, Facebook’s Sandberg and other women leaders met with President Trump in December. Catz happened to join Trump’s transition team, making one Oracle exec to resign. Catz, who is an 18-year old Oracle veteran, became the co-CEO when Larry Ellison resigned in 2014. Catz has an estimate of $670 million of fortune. According to the data, Lee is the only billionaire female founder in tech business. Another thing common amongst these tech women, is that their average age is 53.
