No, just the early statements from Cambridge Analytica and Leave.EU.
Was rather odd that Cambridge Analytica and Leave.EU both claimed to be working together until it started to look bad - https://www.reuters.com/article/us-facebook-cambridge-analyt...

I am not really sure we were good at anything. The company had no direction coming from upper management, so we weren't really able to become experts at anything. The salespeople used the psychographic nonsense to sell to clients, which everyone internal knew was nonsense, so we were sometimes forced to use nonsense to solve problems. We were also forced to tackle impossible challenges because of salespeople's promises. There was very high turnover.
The technical teams were nice and had a lot of smart people. Most were fresh out of uni; first job.

I don't think we were particularly good at marketing, unless you mean marketing ourselves as evil geniuses. In which case we were too good for our own good.
