The internet is broken.

Our data is collected to addict us to content.
It's used to maximise the chance that we'll watch another puppy video, or click a gambling advert.
It can be used to infer if you're part of underrepresented groups and treat you differently because of it.
Our data should be used to create value for us, not for advertisers. It's part of our mission!
Join us to build a future where personal data benefits the humans who created it.
