A private software company.
Sipki is a New York software company. We research and build software in security, trusted computing, AI and data.
Contact usMore decisions are made by software, more data moves between systems, and every result has to be one people can rely on.
AI agents take real actions. They need clear limits and oversight people can rely on.
The more systems touch personal and business data, the more it matters where that data stays.
When computation is shared, the outcome should be something you can verify, not just accept.
Today's records have to stay secure tomorrow, including in a post-quantum world.
Trust should be engineered into software, not assumed.
We build software whose behaviour can be checked, not just taken on faith.
We keep the data we hold to a minimum and, where we can, keep it on the user's own device.
We design for the long term, so what we build today stays dependable as technology moves on.
Six areas, one goal: software people and organizations can trust.
Digital signatures, tamper-evident records and post-quantum readiness.
Verifiable execution and hardware-backed attestation for distributed compute.
Guardrails, oversight and reliable automation for AI agents.
Clean, structured data from public sources and documents.
Software that keeps user data on the user's own device.
Apps for the platforms teams already use.
Our work comes together in three directions. Each one serves the same purpose: making software dependable.
Keeping records and communication secure, now and later.
We work on applied cryptography, including post-quantum readiness, so that what is signed and stored today stays trustworthy for years to come.
Making shared computation and AI agents dependable.
We build software that helps people rely on the results of computation and on the actions of AI agents, with oversight built in.
Useful data, private by default, where teams already work.
We turn public sources and documents into clean, structured data, build software that keeps user data on the user's device, and make apps for the platforms teams already use.
Based in New York. Our software is used wherever people work.

We would rather build fewer things that last than many things that don't.
