Get ready for the 2013 Fierce 15!

After months of combing through hundreds of companies, FierceWireless will name its annual "Fierce 15" winners tomorrow. To qualify, a company must be privately held, well-funded, emerging (founded in the past decade or so) and have the potential to be a major player in the industry. We prefer the firm to be based in the United States, but if it is not, we expect it to conduct a significant amount of business in the U.S. since that is where the majority of our readers are located. Check back with FierceWireless tomorrow to see 2013's winners! In the meantime, here is a look at the winners from 2012. And here are all of FierceWireless' previous winners.
