Andrew: Hey there, freedom fighters. My name is Andrew Warner. I’m the founder of Mixergy.com, home 
of the ambitious upstart. The place where over a thousand of entrepreneurs have come to tell the 
stories of how they built their businesses, had challenges along the way, overcame them, or not, 
and mostly told you what they learned from it. And thousands and thousands and thousands of other 
entrepreneurs have listened and learned, and used what they’ve learned from these interviews.

Today’s guest is David Baggett. He co-founded ITA software, a company that Google bought for a 
reported $700 million. ITA makes software that’s the search engine behind sites like Kayak. It 
actually figures out prices, time and other data like flights.
