ConsenSys is a Brooklyn-based blockchain software company and corporate venture firm founded in 2014 by Joseph Lubin, one of the original co-founders of Ethereum. More than a traditional investor, ConsenSys operates as a studio and incubator for the Ethereum ecosystem – building products internally, funding early-stage projects, and acquiring teams working on infrastructure, developer tooling, and decentralized applications. Its venture arm, ConsenSys Ventures, has backed dozens of projects since 2017, with a strong focus on Ethereum-native protocols and Web3 infrastructure.
The company has raised over $700 million in external funding across multiple rounds. A Series C in 2021 brought in $450 million at a $3 billion valuation from institutional backers including HSBC, UBS, and Mastercard. A follow-on round in March 2022 raised another $450 million at a $7 billion valuation, with participation from ParaFi Capital, Third Point Ventures, Marshall Wace, and SoftBank Vision Fund 2. ConsenSys does not publicly disclose AUM figures for its venture activities. Its geographic focus is global, with particular depth in North America and Western Europe.
ConsenSys operates across two overlapping tracks: internal product development and external investment. The line between the two is often blurred – several of its most successful "portfolio" assets were built in-house before being spun out or scaled independently.
Notable investments and products
- MetaMask – the world's largest non-custodial browser wallet, with over 30 million monthly active users. Built internally at ConsenSys and now its primary consumer product.
- Infura – Ethereum and IPFS node infrastructure used by the majority of Web3 applications. Also built internally; serves as critical backbone for developers who do not run their own nodes.
- Linea – a zkEVM Layer 2 network launched on Ethereum mainnet in 2023, developed natively within ConsenSys as its scaling bet.
- Truffle Suite – a widely used Ethereum development framework that ConsenSys built and maintained for years before deprecating it in December 2023 as developer tooling consolidated around Hardhat and Foundry.
- Gnosis – an early portfolio investment from ConsenSys Ventures; Gnosis became a foundational provider of smart contract wallets and prediction market infrastructure.
- Grid+ – a ConsenSys Ventures-backed hardware wallet and energy settlement startup.
- Codefi – a ConsenSys-internal product suite for DeFi and asset tokenization, targeting institutional clients.
Team
Joseph Lubin is the founder and CEO. He holds a degree in electrical engineering and computer science from Princeton and previously worked in finance before co-founding Ethereum with Vitalik Buterin and others in 2013–2014. He is ConsenSys's primary public voice and strategic decision-maker. Kavita Gupta led ConsenSys Ventures as founding managing partner from 2017 and built out the early investment portfolio before departing. Leadership of the venture arm has shifted over the years as ConsenSys reorganized toward a tighter focus on its core product suite. Public information about the current investment team structure is limited.
Recent activity
ConsenSys has gone through significant restructuring since 2022. The company laid off approximately 100 employees in 2023 – roughly 11% of its workforce – citing broader crypto market conditions and a need to focus resources on MetaMask and Infura. In the same period, it deprecated Truffle Suite, acknowledging that community tooling had outpaced the product. On the legal front, ConsenSys filed suit against the U.S. Securities and Exchange Commission in 2024, arguing that Ethereum is not a security and challenging the agency's jurisdiction over MetaMask's swap feature. The SEC subsequently closed its investigation into Ethereum 2.0. Linea continued to expand with an active ecosystem incentive program aimed at attracting DeFi liquidity and developer activity through 2024 and into 2025. MetaMask Snaps – a plugin system allowing third-party extensions – launched publicly in late 2023 and gained traction as a developer platform.
ConsenSys occupies a unique position in the Web3 investment landscape. It is less a traditional venture fund and more a corporate sponsor of Ethereum's core infrastructure. Its wins – MetaMask and Infura in particular – are foundational to how most crypto users and developers interact with Ethereum. Its setbacks reflect the cost of maintaining a large studio through volatile market cycles. The company's long-term health depends heavily on MetaMask's ability to monetize its user base through swaps, staking, and institutional products, alongside Linea's success as a competitive L2.
