Vana, a Web3 startup that aims to build networks of user-owned data pools, announced Wednesday that it raised an additional $5 million, bringing its total funding to $25 million, led by Coinbase Ventures. Vana also previously raised funding from crypto venture capital firm Paradigm, which led the company's $18 million Series A round. The startup's goal is to build a decentralized autonomous organization (DAO) network that uses its blockchain technology to address the lack of training data for artificial intelligence models, while providing internet users with a way to earn revenue. Vana is one of many companies trying to do business around the intersection between blockchain and artificial intelligence.
