I was part of a UK company that did sovereign data work on NHS data. They would give NHS trusts equity in the company in return for the data, and the data wouldn't leave the company; only results of paid research studies. The idea was to lower the increasing cost of pharma studies through early data-driven work.

The company bid for this contract, and lost to Palantir. I still can't believe that a company trying to do this in exactly the right way lost to a US intelligence company.
