Pool Data is a Web3 data infrastructure that builds a data marketplace and associated payment rails for new data-sharing entities called data unions. It has sectioned its product into a messaging and payments infrastructure, a query-to-data analytics engine, a personal data vault for members, a marketplace, and a wallet for data union members. This makes it streamlined and achievable to set up a data union, facilitating a new layer of relationships between data sellers and buyers. Pool Data's revenue model involves returning the majority of profits to data union members, creating a fair return for those creating the value.
