Aodhan Cullen Founder of StatCounter.com

Aodhan Cullen calls himself a born entrepreneur. He has been running businesses since the age of 12, when he set up his own résumé-typing business. As a young teen, he dabbled in Web site design, and it was this experience that gave him the idea to launch StatCounter, the company he founded in 1999 when he was 16.

When Cullen started designing Web pages, his clients repeatedly asked him whether anyone was visiting their Web sites. So, Cullen formed StatCounter and came up with a way to measure the number of hits on Web sites, the geographical location of visitors to sites, the various pages a visitor views on a site, and the keywords they use to find a site. StatCounter currently has more than 1.5 million members and tracks more than 9 billion page views per month across its network of more than 2.2 million Web sites.
The company, which is profitable, claims to be signing up 1,500 new members per day.

Cullen is 24 and from Dublin, Ireland.
