I've read that many times here, but it's weird because I don't know any. None of my neighbours, clients or partners have had any significant problems with GDPR, in a kinda large tech complex in France (with about 300 startups, though of course I don't interact with all of them). Maybe you mostly have relations with startups that work in the ad industry?
