Ether.fi

Ether.fi builds a non-custodial staking protocol on Ethereum, engineered so that stakers retain control of their assets at all times. Alongside the protocol, the company operates liquid vaults that keep staked assets usable within DeFi, and a crypto-native credit card that connects decentralised finance with everyday payments. The card and related consumer applications serve millions of users.

The technical work spans Ethereum infrastructure, liquid staking mechanics, DeFi protocols and consumer fintech product development. Engineering covers the protocol layer through to end-user applications, with teams taking end-to-end ownership of features. The company describes itself as a lean, technical organisation of roughly 30 people.

Ether.fi states that it has been profitable from day one, operating on real revenue models rather than speculative ones. It reports a long-term orientation, planning on the scale of decades rather than short cycles, and emphasises decentralisation, transparency, accountability and user experience as operating principles. Mistakes are acknowledged and corrected quickly, and the company states a preference for avoiding shortcuts or unsustainable schemes.
