Data privacy and owning our personal data

The last startup I worked on had a mission to enable individuals to take ownership of their personal data. As it stands today, our personal data belongs to businesses.

They have customers, employees and partners that read it. So all you end of getting is fluff and none of the really painful stories that make entrepreneurs who they are.
