The companies ranked in the annual SD&I Fast50 are recognized and ranked based on percentage growth and revenue growth – with their overall ranking balancing those two considerations using a simple but effective algorithm. 

If we ranked companies purely on revenue growth, it would tend to favor larger companies – this way, the playing field is level for all entrants. 

We also balance the equation by studying three years of financial change to ensure that high-growth companies aren’t just “flash in the pan” types of businesses, but are able to sustain themselves. It also balances ups and downs. For example, a company on our list could have had negative growth in its first year but then achieved such strong growth in year two that the average was powerfully in the positive.

To enter, companies confidentially report to us their three most recent fiscal years worth of gross revenues. Using those numbers, we compute the revenue growth and percentage growth for each of their three most recent fiscal years. We average the growth numbers to generate an average revenue growth for the company, and we do the same for the company to create an average percentage growth.

Companies may enter as long as one of their key business efforts is the installation of security solutions (e.g., video, intrusion, access control, perimeter detection, biometrics, etc.). It doesn’t have to be a company’s sole business effort, but it does need to be a definitive part of the firm.
