, but CatN began working with the company over a year ago and has gradually increased the scope of its operations, which led to the travel giant deciding to move its websites away from Accenture.

Computerworld UK spoke to CatN's head of products, Joe Gardiner, who confirmed that the deal is worth more than £1 million.

Gardiner explained that CatN started working with Thomas Cook as a "skunkworks" operation and has ended up consolidating the company's fragmented online systems that were scattered across seven data centres.

He said: "We completed the .com migration to us just before Christmas last year and we had been working with Thomas Cook for about a year at that point. A lot of the reason why they like us is because of our responsiveness, we handle their requests very rapidly.

"I think that they saw that when you work with a lot of these large SIs it becomes about relationship management. Whereas, we give them the mobile numbers of our senior engineers, that's the approach we like to take."
