Here's what women in tech actually think about their employers

We know the stats: women hold about 21 percent of technical jobs at Silicon Valley's top companies.

Many of the women who make up that 21 percent have some feedback about their employers. According to a new report from the jobs site Comparably, the biggest tech companies—and their CEOs—don't make it to the top of the heap when women in the tech industry rate their employers.

The jobs site used its database of salaries, job titles, and employee ratings shared between April 2016 and April 2017 to determine the companies and leaders that women employees rate the highest.

According to the site's analysis, the top eight companies as rated by women who work there are mostly smaller players in tech—not the major names. Nope, Uber didn't make the list.

Here are the top companies, as rated anonymously by their employees:

1. Cornerstone On Demand (a cloud-computing company)

2. Slack

3. Indeed

4. Hubspot

5. Zenefits

6. Zillow

7. Salesforce

8. Chegg

Many of these companies are based outside of Silicon Valley, with Santa Monica, Austin, Boston, and Seattle represented. Of the San Francsico-based names, No. 2 Slack has earned a reputation as a great place to work for women and people of color.

Besides the top companies, women employees rated their own CEOs. The CEOs who earned the top ratings, starting at 98 percent approval and down to 82 percent approval, were:

1. Spencer Rascoff, Zillow

2. Stewart Butterfield, Slack

3. Brian Halligan, Hubspot

4. Brad Smith, Intuit

5. Marc Benioff, Salesforce

6. Adam Miller, Cornerstone On Demand

7. Dan Rosenweig, Chegg

8. Jay Fulcher, Zenefits

9. Hisayuki Idekoba, Indeed

10. Tim Cook, Apple

11. Satya Nadella, Microsoft

12. Jeff Weiner, LinkedIn

Even though these CEOs come out looking good in Comparably's results, they're still all men. But the women working in tech weren't ranking the leaders they wished they had—just the ones they do have.

Anonymous rankings on a jobs site: still not great for Silicon Valley.
