Business at Cyberspeed
“When the Web’s first search engines were created, there were few users on the Internet. It wasn’t until the Web popularized the network, and millions of people began adding documents and searching them, that anyone thought much about how computers could collect and analyze data on searching habits.”

Is Xfire the next MySpace?
“Xfire, which only launched in January 2004, has three million passionate customers who use its PC software an astonishing average of 88 hours a month, according to Cassidy. More amazing facts: almost 300,000 new users join each month, and for two years the service has sustained a 2 percent-plus growth rate — weekly. Its users — in 100 countries (a slight majority are in the United States) — are online for 200 million minutes every day. The reason for the growth can probably be found in a core philosophy that puts users first.”

USA Today - 'Start-up King' Mike Cassidy strikes Silicon Valley gold

By Jon Swartz, USA TODAY

SAN FRANCISCO — Entrepreneurs rarely succeed in Silicon Valley— much less repeat success. … Consider him the Start-up King of Silicon Valley. In short order, he co-founded and was CEO of four [ed. now five] companies — [ed. Apollo Fusion,] Ruba, Xfire, Direct Hit, and Stylus Innovation — that have been sold for more than $600 million. [ed. now $750 million] In a recession-tinged era of few high-tech initial public offerings, where many start-ups fruitlessly seek buyers, the forty-something Cassidy has been able to quickly create and sell companies.

And he's probably not done.

"He's not lucky. He's skilled in finding opportunities and coming up with a solution," says Warren Packard, an investor in Cassidy's second, third, and fourth companies.

Packard has known Cassidy since 1987, when they both worked on a solar race car. They reconnected in 1998, when Cassidy started Direct Hit and Packard was a partner at influential Silicon Valley venture firm Draper Fisher Jurvetson. Cassidy approached the firm for funding.

"He had to convince more than me," says Packard, who is still at Draper. "But he was concise, convincing and informal. He moves fast."

Cassidy landed a $3.5 million investment the same day.
