Just a decade ago, mentioning “women” along with “Silicon Valley” would more likely conjure a crude joke, rather than an image of successful women in the technology sector. But the world is finally recognising that the electronic kingdom is no longer ruled exclusively by men. It’s still a cliff-like climb for gender equality, but there has been some headway. Reddit CEO Ellen Pao is doing away with salary negotiation at her company, while Rachel Haot, deputy secretary for technology at the state of New York, was the first woman to be named the 2014 Chief Digital Officer (CDO) of the Year by the CDO Club. As shown in the list on the right, wealth intelligence firm Wealth-X has finally compiled a ranking of the most affluent women in tech.

These are some hopeful sums for women looking to make a mark in the industry, but they are unfortunately still glaringly lower than what tech’s most successful men earn (see sidebar). But events like Women In Tech and crowdfunding competitions like Women Startup Challenge are doing their bit for a fairer world for the fairer sex.
