The best example I can think of is Dash DAO. The Decentralized Autonomous Organization has multiple centralized groups such as Dash Core, DashForceNews and also film makers and Sports teams and also individuals who are not a part of any centralized group.
A person may work individually and later decide to join a centralized group or vice versa.
You could also take the crypto projects as examples.There is Cobinhood DEX which run on Ethereum and there is BTS which doesn't run on some other platform.
