Aragon is a project oriented around Distributed Autonomous Organizations, or DAOs. Here is an excerpt from the Aragon whitepaper:

• Aragon is a DApp that lets anyone create and manage any kind of organization (companies, open source projects, NGOs, foundations, hedge funds...) on the Ethereum blockchain.
• Aragon implements basic features of an organization such as a cap table, token transfers, voting, role assignments, fundraising, and accounting. The behavior of an Aragon organization is easily customized by changing the bylaws. In addition, Aragon organizations are extensible through third-party modules that interact with the organizations' contracts.
• Aragon Core is a set of smart contracts written in Solidity that allow a distributed team to self-organize and handle activities that are part of a typical centralized organization, easily, for instance, handling payroll, internal arbitration, and so on.
• The smart contracts in Aragon Core have been used by other projects, such as districtOx, as a foundation for more advanced functionality. If your project involves any sort of distributed governance, it would make sense to look into Aragon Core.
