The World’s 10 Most Powerful Women In Technology

Here are the world’s 10 most powerful women in technology as profiled by Forbes:

#8 Sheryl Sandberg, 45, COO, Facebook

This former Google executive joined Facebook in 2008 and became the first woman on its board four years later. Sandberg helped the social network scale globally,

go public and expand digital revenue. Earlier, the Harvard MBA was a World Bank economist and chief of staff to then-Treasury Secretary Larry Summers.

#9 Susan Wojcicki, 46, CEO, YouTube

In February 2014, Wojcicki moved from her post as consigliere for Google’s ads and commerce (some 90% of revenue) to become CEO of Google-owned YouTube, the world’s largest video platform. In 2006, Wojcicki championed the $1.65 billion acquisition of the video site. YouTube, with more than 1 billion unique visitors a month, is now valued at some $20 billion, with 2014 revenues hitting $4 billion, up 33% from the prior year.

#13 Virginia Rometty, 57, CEO, IBM

More than three years have passed since Rometty took the helm at IBM and it’s been anything but smooth sailing. With 11 consecutive quarters of revenue declines, IBM is sticking to its focus on boosting profit margins and cultivating growth. Under Rometty the technology giant has been shifting its portfolio of businesses. She has led spending programs for data-analysis software and skills, cloud computing and Watson artificial intelligence technology. At the same time IBM has sold businesses that generated billions in sales but lost money or broke even, including its chip-manufacturing operation and a division that made low-end server computers. Rometty joined IBM at age 24 as a systems engineer in 1981 and became the company’s first female CEO in 2012.

#14 Meg Whitman, 58, CEO, HP

The Hewlett-Packard CEO Meg Whitman has helmed the $112 billion (revenues) tech company since 2011 and became chairman in 2014. Nearly all of her fortune, though, comes from her decade-long stint as CEO of online auction house eBay, which she helped expand from 30 employees and $5 million in sales to more than 15,000 employees and $8 billion in revenue. A Princeton graduate with a Harvard MBA, Whitman did stints at Hasbro, the Walt Disney Co. and Bain & Co and today sits on the Procter & Gamble board.

#22 Marissa Mayer, 39, CEO, Yahoo, Inc.

Since taking the helm three years ago, Marissa Mayer has upgraded content — including hiring journalists Katie Couric and Matt Bai — and pursued an aggressive acquisition strategy aimed at boosting mobile revenues. But sales growth has remained sluggish, and Mayer has faced pressure from activist investors to cut costs and improve financial performance. In January 2014, Mayer announced plans to spin off Yahoo’s stake in Chinese e-commerce behemoth Alibaba. The move will put the focus back on Yahoo’s core business and Mayer’s ability to turn it around. Much of Mayer’s personal fortune comes from what she accumulated during her 13 years at Google, where she was among its earliest employees. The Yahoo chief’s pay package jumped 69% to $42 million in 2014, making her one of the country’s highest-paid CEOs.

#24 Safra Catz, 53, Co-CEO, Oracle Corporation

One of Larry Ellison’s closest confidants, Safra Catz became co-CEO of his software giant Oracle in September 2014. A 16-year vet of the company, she’s been richly rewarded with stock options and is one of world’s highest-paid female executives, earning nearly $38 million in 2014. The Israeli-born, Boston-raised executive is credited with spearheading its aggressive acquisition strategy. She played a role in closing over 85 acquisitions over the past five years helping to cement Oracle’s dominant position in the world of enterprise technology.

#25 Angela Ahrendts, 54, Senior Vice President, Apple, Inc.

The first woman on Apple CEO Tim Cook’s executive team, Ahrendts started as SVP of retail and online stores at Apple this spring. The gadget giant created the role for her after the former Burberry CEO, credited with turning around the ailing fashion house, grew revenues to more than $3 billion and stocks returned 300%. She’s also the first person responsible for 400+ brick-and-mortar stores as well as online retail efforts. Before Burberry, Ahrendts held leadership positions at Liz Clairborne, Henri Bendel, and Donna Karan International.

#29 Ursula Burns, 56, Chair-CEO, Xerox Corporation

In her five years as CEO, Ursula Burns has managed to make Xerox–once only known for its carbon copies–a viable and profitable company. This past year, Burns helped Xerox generate adjusted earnings per share of $1.09, up from $1.02 in 2012, and post $21.4 billion in full-year revenue. She recently told shareholders that she would continue to sharpen the company’s technology-driven, services-led portfolio. Services represents 57% of the company’s total revenue and is expected to grow to two-thirds by 2017. Burns is a Xerox lifer, beginning her career in 1980 as a summer intern.

#32 Ruth Porat, 57, Chief Financial Officer, Google, Inc.

Longtime power woman on Wall Street, Ruth Porat is moving coasts and taking her talents to Google. After joining Morgan Stanley in 1987, Porat survived the stock market crash untouched. She worked closely with fellow Power Woman Mary Meeker, and moved on to become Morgan Stanley’s vice chair of Investment Banking, global head of the Financial Institutions Group and in 2010, its CFO. During crisis bailouts in 2008, Porat kept a cool head: She helped advise the U.S. Treasury and NY Fed on Fannie Mae, Freddie Mac and AIG. Porat leaves the bank after one of its strongest quarters in recent years — trading and wealth management profits swelled 60% in 2015’s Q1 — and is expected to earn at least $70 million during her first two years at Google.

#33 Lucy Peng, 42, CEO, Ant Financial Services, Alibaba Group 

Alibaba’s most powerful woman executive heads the group’s fast expanding stand-alone financial services unit, which serves about 615 million users. Ant Financial, formerly known as Small and Micro Financial Services Company, serves mostly small borrowers and depositors who, like most things online, possess extraordinary strength when combined. It is made up of Alipay, China’s version of PayPal and the engine powering the entire Alibaba e-commerce world; Alipay Wallet, a mobile payment service provider, among others. It recently added MYbank, commercial banking for small clients. An IPO for Ant Financial is in the cards, and its value has been estimated between $35 to $40 billion. Peng was a cofounder of Alibaba and continues to serve as its chief people officer.
