To say that the market for cloud startups is hot right now would be an understatement. Some of the biggest exits of the past few years have been cloud companies, and the market seems to be getting stronger.

Startup accelerators are a great place to look for the next big cloud companies or trends. On Thursday, April 9, Techstars hosted its Techstars Cloud Demo Day at the Aztec Theatre in San Antonio, Texas.

“Cloud is a general enough vertical that we can get companies that are working on a variety of different things that fall within that vertical,” said Blake Yeager, managing director for the cloud program at Techstars. “And, it allows us to attract from a much larger geography.”

The companies represent six different countries and run the gamut on what aspect of business they are engaging with cloud technology.

Cloud startups often prove a great asset for enterprises looking to innovate. Here’s what you need to know about the 10 companies that presented at Techstars’ demo day.
