Just to make us all feel better, he's taking along Ben Warner, whose brother Marc runs an AI company called Faculty.
Faculty, along with Peter Thiel's company Palantir, and NHSX, are sucking in NHS patient data and potentially phone location data.
This is being permitted with a view to creating a database for tracking people potentially to allow contact-tracing.
However this model of having a centralised database tracking the movements of every member of the population with a smartphone is highly controversial. Apple and Google are developing a much less intrusive model, which doesn't involve either a government or a private company having a full database of all this information about the population.

To make things even more fun, some of the people and companies involved are better known for less benign uses of data. Cummings is still in contempt of Parliament for refusing to appear in front of the committee on Fake News, and he (and reportedly Ben Warner) worked for the Vote Leave campaign which employed Cambridge Analytica. (Cambridge Analytica processed illicitly harvested Facebook data, and used bankruptcy to attempt to escape investigation into this.)
Palantir is using Foundry for the database, the same platform that it uses to do intelligence work for governments. So presumably there's the potential to do fairly easy cross-referencing after Covid is over, should the tracking database come in useful for... anything else.
