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.
Kraken is one of the oldest and largest cryptocurrency exchanges in the world, founded in 2011 and launched in 2013 by Jesse Powell after the Mt. Gox security failures convinced him crypto needed an exchange built on trust. Operated by parent company Payward, Inc., Kraken lets retail and institutional clients buy, sell, trade, stake, and self-custody dozens of digital assets, alongside crypto futures, margin, and index products. By late 2025 it served over 5 million funded accounts, held tens of billions in client assets, and was preparing for a public listing.
