Fireblocks
Fireblocks began with a $200 million crypto heist and a stubborn question: how do you move digital money without handing attackers the keys? Eight years later, its answer has become an operating system for institutions moving value onchain.
Eaglebrook
Eaglebrook is a New York-based crypto investment platform built for wealth managers. It gives registered investment advisors (RIAs) and their clients direct, tax-optimized exposure to Bitcoin, Ethereum, and other digital assets through separately managed accounts (SMAs) held at institutional qualified custodians. As an SEC-registered investment advisor, Eaglebrook operates one of the largest crypto SMA platforms in the market, integrating with advisors' existing portfolio-management and reporting systems so they can offer, trade, bill, and report on digital assets inside their normal workflow.
Cubist
Cubist is a security-first Web3 infrastructure company that builds hardware-backed key management and confidential compute for digital assets. Its flagship platform, CubeSigner, keeps cryptographic keys sealed inside secure hardware (HSMs and AWS Nitro Enclaves) while giving developers low-latency signing through revocable sessions and a programmable policy engine - resolving the old tradeoff between cold-wallet security and hot-wallet speed. Founded by applied cryptographers and security researchers from Carnegie Mellon and UC San Diego who designed primitives underlying Ethereum and Avalanche, Cubist serves staking providers, DeFi protocols, bridges, and institutions building on internet capital markets.
