It's isn't often you see one of the companies that we write about make it to the top of Inc. Magazine's list of fastest growing private companies (note 1). But this year, Timonium, MD-based Bill Me Later landed at number six.  

To make it to the top, it takes an amazing amount of growth over a three-year period; in Bill Me Later's case, 87-fold, usually combined with a very small number in the base year ($600,000 in 2003) to top the chart (note 2). 

The self-reported revenue figures for the company are:

2003: $610,000
2006: $53.6 million
3-Year growth: 8,650%
Number of employees: 100

The company's been on a fabulous run and it will be interesting to see how long they stay private. Depending on the credit quality of the company's receivables, it could be an attractive acquisition target for a traditional financial institution or for a certain Web-based payment giant. 

Two other companies we follow made the top 500:

#205: CreditCards.com (Austin, TX) with an amazing $43 million revenues, up 10-fold from its $3.7 million in 2003. With 16 employees, the company does almost $3 million per.

#382: CashEdge (New York, NY) up 7.5 fold from $2.4 million in 2003, to $20.4 million last year, 315 employees. 

Congratulations to this year's high fliers.

Notes:

1. The Inc. list was expanded 10-fold this year to 5,000 companies 

2. The percent-growth rankings are far more dependent on the denominator than the numerator. If Bill Me Later would have had $400,000 less revenue in 2003 they would have grown 268-fold and topped this year's list. However, even $10 million more in 2006 revenues would only push them up one spot.
