One of the earliest connections between Cambridge Analytica and Aggregate IQ is the fact, reflected in the code and the commentary from the employees, that they got the original software for the Ripon platform from a server owned under the name of Alexander Nix, who was the recently departed CEO over there at Cambridge Analytica SCL Group. So there is that direct tie-in.
One of the apps that was developed by AggregateIQ is a phone, community outreach, and voter-influencing messaging platform. It operated on a domain known as dclisten.com, which is also registered under the name of Alexander Nix. There are plenty of examples of resources and assets flowing between these two groups.
