The Enterprise Ethereum Alliance is an organization comprised of thought leaders from around the globe working together to promote and support best practices and standards around Ethereum -based blockchain technology. 
In March of 2017, the Enterprise Ethereum Alliance launched with a group of 30 companies that included heavy hitters like BP, The Bank of New York Mellon, CME Group, ConsenSys, Credit Suisse, ING, Intel, J.P. Morgan, Microsoft, and more. As of May 2019 that number has grown well beyond 500 members. The EEA has created an effective network of Fortune 500 companies, startups, academics, and blockchain enthusiasts to align interests within the blockchain industry and facilitate growth and expansion of Ethereum-based blockchain technology. One of the ways the EEA accomplishes this is by splitting into various groups that support each other such as a communications protocol working group, a healthcare working group, an insurance working group, a legal industry working group, and many more. 
The official EEA website defines four visions: 
- Be an open-source standard, not a product: The EEA will define open-source standards for the development and operation of Ethereum’s blockchain across its member companies.
- Address enterprise deployment requirements: The EEA will facilitate and govern cross-deployment across its members for various business needs and use cases wherever applicable. For example, if one bank implements a blockchain-based KYC platform on Ethereum, then the EEA can help another member company to implement the same when and where required. This will save a lot of money in development cost.
- Evolve in tandem with advances in public Ethereum: EEA members will be making their private blockchains using Ethereum technology, but they can always get subject matter experts and best practices from the existing public blockchain of Ethereum. Hence, both the public and private versions will advance together.
- Leverage existing standards: Ethereum’s public blockchain started in July 2015, making it already 3 years old. The standards and experience of the old blockchain can be leveraged by the new blockchains which the EEA members will form in the future.
The Enterprise Ethereum Alliance holds several events throughout the year. The events generally touch on topics like KYC and AML regulations, creating Dapp's for the Ethereum blockchain, and other developments in the Ethereum landscape. 
Only people who are promoting and facilitating Ethereum-based projects are eligible to join the Enterprise Ethereum Alliance. Membership for individual, groups, or companies with less than 50 people is $3,000 per year. For companies with between 51 to 500 employees, this fee is $10,000 per year. For companies with 501-5,000 employees, the fee is $15,000. Finally, for companies with more than 5,000 employees, the fee is $25,000.
