It’s no secret that there’s a gender disparity in the tech sector. According to Bloomberg Businessweek, only 3% of tech entrepreneurs are female, and only 6% of CEO positions at the top 100 tech companies are held by women. Yet stats also reveal that woman-owned tech companies get a 35% higher investment return than male.

Although gender equality remains a global challenge, glass ceilings are beginning to break. The tech industry is becoming much more self-conscious about its diversity issues and have begun to make positive strides toward fixing them.

As our world continues to be driven by innovations in technology, we need more women driving tech. Closing the gender gap will improve creativity, productivity and performance. Listed below are a few of the women leaders we admire.
