"One problem with the Vote Leave / AIQ / Cambridge Analytica theory floated by Wylie was that while AIQ did the actual ad-buying – the company’s speciality – its actual 'data science' was done by a different firm, ASI Data Science (now rebranded as Faculty), a low-profile company that had previously worked with the Home Office on tracking online extremism on Facebook, among other clients.

The other was that no-one could produce any evidence to suggest Cambridge Analytica and Aggregate IQ were anything other than separate companies who had seen some personnel overlap, and who had worked together."
