Founded in 2014 by Ethereum co-founder Joseph Lubin, ConsenSys is a Brooklyn, New York based blockchain company that develops infrastructure and decentralized applications (dApps) for the Ethereum blockchain

There are five major branches of ConsenSys, each aimed at building the infrastructure of dapps. ConsenSys Labs is an accelerator and venture arm of the company aimed at supporting entrepreneurs and developers in early-stage blockchain projects. ConsenSys Academy is an online end-to-end developer course that helps people start coding on the blockchain. The job kit provides a variety of resources about the skills needed to become a developer as well as provide resources as to where to get started. 

ConsenSys Solutions works with businesses around the world to build, test, and launch blockchain-based solutions for their companies. ConsenSys Diligence is designed to protect the ethereum ecosystem through security, legal and technical guidance. Finally, ConsenSys organizes a global conference series, Ethereal Summit.

ConsenSys Labs, a $50 million blockchain venture fund, was launched in 2017. Its aim is to help founders in the space by giving them capital, networking opportunities and an accelerator program for what they call web3 (a decentralized web) to build on the ethereum network.  At the end of Q4 in 2018, ConsenSys had more than 50 ventures under its umbrella.

In 2016, ConsenSys partnered with Microsoft in order to build dApps in Microsoft’s Visual Studio programming platform. Together, they created an extension for the platform to allow smart contract development in the Solidity programming language (which Ethereum is written in) in Microsoft’s Visual Studio programming platform.

In December 2018, ConsenSys laid off 13 percent of its staff. At the company’s height that year, ConsenSys employed over 1,000 people. In 2019, it formed a partnership with Hyperledger and the launched of Codefi, a suite for decentralized finance solutions, but was forced to cut back 90 more staff in April 2020.
