The ability to rent computers and software over the internet, aka cloud computing, has forever changed the computer industry. 

But that doesn’t mean that every cloud startup is a good bet for a prospective employee.

So, at the behest of venture capitalist firm Battery Ventures, job hunting site Glassdoor has come up with a list of the best cloud companies to work for, based on employees’ overall ratings shared with Glassdoor.

All of the companies on this list are growth stage startups that employ at least 200 people.

Glassdoor included the top 50 companies on its full list. We further whittled that down to companies that received a high overall rating, had 90% or higher approval of the CEO and where 90% or more employees say they think the company is going in the right direction.

Based on that criteria, here’s the skinny on the 18 best cloud startups to work for.
