Giorgos Zacharia Biography

Giorgos Zacharia has been appointed Chief Technology Officer (CTO), replacing KAYAK Co-Founder Paul English, who left the company at the end of 2013 to focus full-time on his newly formed incubator, Blade.

As Chief Product Officer, Giorgos oversaw the company’s global technology strategy and product development for KAYAK’s websites and mobile applications. He joined the company in 2008 as Chief Scientist. Prior to joining KAYAK, he was co-founder and CTO of Open Ratings, Inc., a leading supply risk management provider. Giorgos also co-founded two machine-learning driven hedge funds, Stocknomics and Emporics Capital Management. He holds four math and computer science degrees from MIT, including a PhD, won five medals in the International Mathematical and Physics Olympiads and was a Fulbright Scholar.

“It’s been ten years since Paul and I founded KAYAK. His passion, creativity and leadership are incomparable. To say he’ll be missed is an understatement,” said KAYAK CEO and Co-Founder Steve Hafner. “Paul’s greatest contribution though has always been his ability to build a world-class technology team, and Giorgos will continue creating the best place to plan and book travel.”

“This has been the best job of my life, and I’m incredibly lucky to have worked with everyone on the KAYAK team,” says Paul English, co-founder of KAYAK. “I’m proud of what the team has created in terms of culture, product and value. I’m looking forward to what the team will accomplish under Giorgos’ leadership.”
