Women are (relatively) few and far between in the tech industry.
They make up less than 10% of venture capitalists, and they leave the industry at twice the rate of men, according to a recent study by the Kauffman Foundation.
There’s also a shortage of women pursuing engineering, particularly software engineering.
But the women who do choose to enter the tech industry in one way or another are doing incredibly important work.
Over the last couple of weeks, Business Insider accepted nominations for the most important women 30 years old or under in tech. We combined those nominations with our own research to give our readers a definitive list and ranking.
We were truly blown away by the number of young, successful women in the tech industry. These women hold a variety of roles in the industry: founder, CEO, engineer, venture capitalist — you name it.

She spoke at WNYC's recent Women in Tech panel at the Greene Space - she always makes me look at things in a new light. That day she pointed out that we are leaving out a huge number of poor women who could be hugely helped by technology, if only developers would design something for them.'
