There is newfound cognizance within venture capital firms that their all-male habit is a problem. VCs acknowledge that diversity within a firm leads to better financial returns, and some founders have even made rumblings in recent months that they would look down on firms — and perhaps walk away from deals — that have a team that does not reflect some sort of diversity. Nothing motivates change like the bottom line.

Within the first two years of working in a tech job, women in the U.S. ask for and receive 98 percent of what their male counterparts make in the same job at the same company, according to the report. Over time, that disparity grows. On average, women with seven to 10 years of experience, for example, ask for about 90 cents on the dollar and are offered slightly more — 93 cents for every dollar a man is offered. Women with 13 to 14 years of experience ask for 94 cents for every dollar and receive just 92 cents.
