Revenue per Customer for 4 CDNs

Below are some interesting numbers. I decided to calculate the annual revenue per customer, and compare them across 4 different CDNs. The numbers are guesstimates at best, with the exception of Limelight. Limelight provides the actual number of customers in its 10-Q. I won’t draw any conclusions from the numbers below, but I will say that startup CDNs must figure out what tier they want to compete in.

According to a Fortune article, Akamai had 881 customers in 2008, and 1,000 in 2010. I took 5% growth from 2008 to 2013, and came up with 1,235. It might be right on the money, or it might be way off. My guess is that Akamai had $1.5B in revenues in 2013.

According to Rayburn, EdgeCast generated $100M in revenue in 2013, and had 6,000 customers.

CloudFlare has 1.5M customers. I will guesstimate that revenue is $100M, and use that for my calculations.
