We're revolutionizing trust in the digital world.

Our Mission

Our mission is to enable, at scale, companies to achieve self-sufficiency with respect to managing authentication, data ownnership, and identity, independent of big tech and other centralized services.

Our Values

We believe that individuals, families, companies, and nations should have the ability to interact and share data digitally with confidence that the communications are authentically relayed and that privacy is ensured without implicitly entrusting security to centralized, unaccountable tech services.

We believe that technology should support our exploration of the human experience, not the mass subjugation thereof for the benefit of a few. We recognize the primacy of the individual, the family, the company, and the country in deciding how each should protect and govern at their respective levels.
Trust minimization.
We aim to minimize the amount of trust you are required to place in third parties, Keychain included. We provide you the ability to managed cryptographic identity in a censorship-resistant way independent of unaccountable third parties, thereby giving control to those who actually bear liability (you).
Customer focus.
We offer data-security technology that solves real problems as experienced by you, and we define our success by your success. Further, we use standardized algorithms and data formats to minimize lock-in, ensuring that you have the ability to transform and verify your data independent of Keychain. You manage your keys, and you own your data and identities.
We design with simplicity as a salient goal. We avoid applying solutions whose main benefit is sounding cool. That said, we follow wherever the problem leads us, even to unconventional solutions if necessary.
