The Inc. 500/5000 was recently released and it ranked the top fastest growing Maryland companies, based on their three-year revenue growth rate.

This is a GREAT list that offers insight into the revenues of dozens of privately held companies. (Admit it: you're nosy like me and want to know what all these small companies are all making around us!)

There are numerous technology companies on this list, some of which I've written about, such as Millennial Media and Aegis Mobile (Maryland's high-tech firm of the year).

The list also is an indicator of the types of businesses that are strong in Maryland: innovative energy and technology companies, systems integrators, cybersecurity and software and project management firms. Firms that deal in government contracting are, of course, well represented.
