In 2009, only 9.5 percent of venture-backed startups had a female founder, according to a research by CrunchBase. By 2014, that figure had almost doubled, reaching 18 percent. During that period, the absolute number of companies with a female founder quadrupled. More women are also seeking early stage funds. The University of New Hampshire's Center for Venture Research (CVR) reports that more than a third of entrepreneurs seeking angel capital in 2014 were women. Despite this progress, women entrepreneurs remain underrepresented in high-tech entrepreneurship. A recent academic article found that women often have to rely on their technical resumes and personal referrals to overcome the biases of investors.
