Glad to hear Skyscanner are on the list, they've been one of the best things to happen to the Scottish tech scene, both in terms of raising its profile and sponsoring (and hosting) many of the meetups in both Glasgow and Edinburgh.
I'm a founder of a spin-out called Scoop Analytics [1] from the School of Computing Science at University of Glasgow. Skyscanner has been incredibly generous and have recently given us and a number of other student-led startups from the School access to space in their Glasgow office to work from. If that doesn't demonstrate their commitment to improving the Scottish tech scene, then I don't know what does.
(We're at the bank of desks next to the Chill Zone if anyone from Skyscanner wants to come and say Hello!).
