80% of Silicon Valley 150 companies had only one woman director or none at all.
And we’re not just talking about four-person startups; the average number of employees in these 150 companies is 8,500. Comparatively, 98% of companies in the S&P 100 — which average 170,000 employees each — had at least one female director, and almost 70% had between two and three.
… and recent data suggesting that despite the prevalence of coding programs aimed at girls and women, only 12.9% of Silicon Valley engineers are women.
