Meet Birmingham's Fastest Growing Companies for 2015

Remember a few years ago, when many were saying "flat is the new up" and decrying the "new normal" in the business world?

Those days are gone in Birmingham, at least for many companies. The Birmingham Business Journal recently compiled its annual FastTrack 30 List of the Magic City's fastest growing businesses, and the companies on the 2015 edition are shattering any notions that big growth is gone.

You can meet the 30 companies in the gallery above, learn about their business models and see some of their advice for growing businesses.

From franchises to tech startups and car washes to burgeoning biotech firms, this year's FastTrack is one of our most impressive classes. The average revenue growth for companies on the List was 100 percent. Nearly half of the companies doubled their revenue from the previous year, while some tripled it.
