Hagan Major

President & Chief Operating Officer

Hagan quite literally grew up with the online advertising industry. In 1999, while still in high school, he started ClickHype, an ad network that eventually served over 100 million ad impressions per day. After ClickHype was sold, Hagan co-founded, an advertising service for users of social networks. As CEO, he grew the site from a mere 500 visitors per day to the top of the Alexa Internet Traffic Rankings with as many as 30 million unique visitors daily. In 2009, he co-founded YellowHammer, an online advertising company funded by a personal credit card. Over the past 5 years it has grown rapidly, landing at #37 on the Inc. 500 list of fastest growing private companies as well as opening offices in the United Kingdom and Brazil.
