Casa has always tried to build our product to support a spectrum of needs between simplicity <> security. Want to go simpler and trust Casa more? You can do that with a yubikey as your signer which is literally two taps for all actions. Want to go more hardcore and trust Casa less? Remove the mobile key, use airgapped hardware wallets, roll dice, have a field day. Then we wrap all of that in a clear and straightforward app where you always know what is going on, and have support from a team of experts that are always in your corner. 8 years and counting - building for the long term.

Casa is first and foremost a security company. Do you have the skills to fight on the front lines with us? We're currently seeking a DevSecOps engineer to continue innovating our security posture in a variety of areas.
