For those investors looking to beat the , Glassdoor could have the answer.
Glassdoor is the rapidly growing privately held online job and recruiting marketplace. Its goal is to help people find jobs they love, while creating transparency surrounding topics like salaries.
On National Equal Pay day Tuesday, Jim Cramer spoke with Glassdoor's co-founder and CEO Robert Hohman.
"I think where you go to work is probably one of the most important decisions that you will make. When people make a bad decision, it is bad for them. When companies make a bad decision, it is really expensive for companies," Hohman said, "People make bad decisions all the time because there is not enough information and data to help make better decisions."
According to Hohman, many investors turn to Glassdoor to find out what is going on with management teams. They may also search for potential issues within a company that may not be available yet, but are being shared by employees.

Glassdoor tested the theory by reviewing the companies with the highest employee reviews. Companies did not apply to participate, employees merely engaged with the service.
"It turns out that no matter how you put together these portfolios, you can build various portfolios from these best places to work companies, every single one of them beats the S&P by a large margin," Hohman said.
Hohman added that according to Glassdoor's research, six out of 10 people do not want to work for a company that does not pay equally. Thus, the company's brand and ability to attract younger talent is directly linked to equal pay.
"Human capital is typically half to two-thirds of a company's cost … and it matters a lot whether those people are highly engaged," Hohman said.
