Endsight has made this list every single year since 2008. The MSPmentor 100 is an annual survey conducted October through December by MSPmentor and its owner, Nine Lives Media, a division of Penton Media. Instead of ranking MSPs merely by total revenue, we calculate an index measurement using such metrics as overall managed services revenue, overall managed services revenue growth, percentage managed services revenue growth, managed services revenue per employee, number of devices managed, and other data points comparing year-over-year results. This index approach ensures small, midsize and large MSPs from around the world are recognized on the MSPmentor 100. 

*The MSPmentor 100 changed it's name to MSPmentor 501 in 2013. your social media marketing partner
