If 2007 to 2009 was "The Great Recession," then the following years have been "The Great Uncertainty" as the economy has grown in fits and starts. Throw in a few seismic changes reshaping the IT industry, such as cloud computing and mobility, and it adds up to what have been some of the most challenging years to manage, let alone grow, a solution provider business. And yet some solution providers have managed to grow quite well in these turbulent times.

The solution providers on this year's Fast Growth list have just short of $24 billion in combined annual revenue, up from $21.1 billion last year, $10.4 billion in 2011 and $5.3 billion in 2010.

Here we present the top 25 on the Fast Growth 2013. The list in its entirety is available exclusively on the CRN Tech News App starting on September 23.
