About RIVER

RIVER is a new social platform that redefines how personal data is owned, controlled, and monetized.

On RIVER you can do all the things you love – Chat, Share, Search & Shop – but only on RIVER, can you see ALL your data. You decide what to sell, to who, and for how long….and what to keep private.

The more you play, the more RIVER will pay! It’s $$ for data, on your terms.

In the digital world, your data is your identity. Take back control of your digital life. Own your identity.

It’s Your Data, Your Life.
