Is anyone involved in Web3 business? What do you do?

Some people say Web3 is the internet of the future, but others think it is just a buzzword. I'm personally interested in DAO since it seems like a new way of managing organizations and funding interesting projects that usually get overlooked. Is anyone involved in Web3 or do you know any successful web3 businesses that your friends are running? What kind of business is it? Please share your experience and thoughts:)
