Privacy-preserving data aggregator

We at Fortress have been developing privacy-preserving data infrastructure for enterprises and have recently been considering rolling out an application that allows individuals to aggregate sensitive personal data (financial, healthcare, maybe even browsing data) and store it within a secure enclave that they control and can grant/sell privacy-preserving access to the data to third party service providers.

Wondering: Would privacy-conscious Brave users be interested in such a platform? (If so, why? If not, why not?)

Any and all thoughts/feedback welcome!
