KJA Holdings LLC
A privately held technology company.
We own and operate Pully — software that lets a person prove who they are, and know who they are talking to, without handing over anything about themselves in exchange.
What we do
KJA Holdings LLC is the parent company of Pully. We build and operate the product ourselves: the applications, the servers behind them, the cryptography they rely on, and the developer tools that let other businesses build on top. We are not an investor, an incubator, or a holding vehicle for outside assets. Everything under this roof is something we made.
Our work sits on a single conviction: identity online is broken in a way people have quietly accepted. Passwords are reused because remembering hundreds of them is not a thing humans do. A phone call from a bank is indistinguishable from a phone call from someone pretending to be a bank. The ordinary defense — collect more information about everyone, all the time — makes the problem worse, because every collection is a future breach.
Pully takes the other path. It gives a person a cryptographic identity that only they hold, and lets them prove it without disclosing anything. We built it so that we, the company operating it, cannot read our users' messages, hear their calls, or sell what we know about them — because we deliberately never learn it.
Our holdings
Pully
Wholly owned · Operating
A private identity and communications application for iOS, with Android in development. Pully replaces passwords with a cryptographic identity you control, works as an authenticator, and carries private messaging, voice and video calls, and events between people who have chosen to be reachable to one another.
Published on the App Store. Developer documentation and a “Sign in with Pully” integration are available to businesses that want their customers to log in without a password.
How we operate
We collect nothing we don't need
The strongest guarantee a company can offer about your data is not to hold it. Pully is designed so that the information a breach or a subpoena would expose largely does not exist on our servers.
We operate what we build
Applications, backend, cryptography and developer tooling are built and run in-house. There is no third party between a customer and the people responsible for the product.
We build for the long horizon
Our cryptography is versioned so it can be migrated as the field moves, including toward post-quantum algorithms, without stranding the people who already trust it.
We answer for our decisions
Privately held and self-directed. Product decisions are made by the people who have to live with them, and correspondence reaches a person rather than a queue.
