Evervault
Evervault is a developer-first encryption platform that lets companies collect, store, process and forward highly sensitive data - especially payment card data - without ever handling it in plaintext. Founded in 2019 by Irish entrepreneur Shane Curran, the New York and Dublin based company pairs a dual-custody encryption model with products for card payments, secure enclaves and network proxying. It processes over $5 billion in transaction volume and generates more than 100 million encrypted tokens per month for customers including Ramp, Rippling and CarTrawler.
Shane Curran
Shane Curran is the founder and CEO of Evervault, an encryption infrastructure company he started in 2018 after dropping out of University College Dublin three days into a business and law degree. A year earlier, at 16, he had won the BT Young Scientist and Technology Exhibition with a post-quantum encrypted storage project called qCrypt. Evervault sells developer-facing tools that keep sensitive data - card numbers, health records, keys - encrypted while still being processed, running inside AWS Nitro Enclaves. The company has raised $46 million from Sequoia, Kleiner Perkins, Index Ventures and Ribbit Capital, most recently a $25M Series B in March 2026.
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.
