Companies
Flashbots
Flashbots started in 2020 as a research and development organization formed to mitigate the negative externalities and existential risks posed by MEV. Since then, we have impacted the world of crypto through mev-geth, Flashbots Protect, MEV-Boost, MEV-Share, our open research and soon-to-be SUAVE. Our mission is clear: illuminate, democratize and distribute. We seek to ensure that the value created on decentralized, public blockchains is transparent and distributed. We do this by conducting cutting-edge research, building mission-critical products, and coordinating a diverse community with competing interests. Our vibe is astro-pirate-punk: irreverent, anarchic, excellent, autonomous. We’re explorers, hackers, builders, thinkers. We are relaxed, composed, and at ease in the world, but beneath our suave exterior, we do not have the time or inclination to be anything but the best.

Our real-time Dune Analytics dashboard showcases billions in cumulative trading volume and a rapidly growing user base. As we continue to scale, CoW DAO remains at the forefront of DeFi innovation, prioritizing security, efficiency, and decentralization.
Aztec
At Aztec, our goal is to add privacy to Ethereum. In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness. Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions. Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge. Now, we’re building a first of its kind Layer 2 with private smart contracts. This requires new cryptographic primitives, a zero-knowledge DSL for writing contracts, a privacy-friendly execution environment, a carefully designed set of circuits that prove the validity of the chain to L1, a decentralized block-building and proving mechanism, and a top-tier user and developer experience. And it’s now time to bring it to market. We’ve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and we’re growing quickly.
Lido
Lido is a liquid staking protocol backed by industry-leading staking providers that supports staking for Ethereum. Lido lets users stake their tokens - without locking tokens or maintaining infrastructure - whilst participating in on-chain activities, e.g. lending, farming and more. Lido is on a mission to make staking simple and decentralized, whilst opening up staking to as many people as possible.
