Securing the future of cryptography
Quantum computers will eventually break the encryption that protects the internet. PostQ exists to make sure that when that day comes, your infrastructure is ready.
Make post-quantum cryptography accessible to every engineering team
The threat of quantum computing to modern cryptography isn’t theoretical — it’s a matter of “when,” not “if.” Nation-state adversaries are already harvesting encrypted data today with the expectation of decrypting it once quantum computers become powerful enough. The urgency is real.
Yet for most engineering teams, migrating to post-quantum cryptography feels overwhelming. The algorithms are new, the tooling is immature, and the migration path is unclear. PostQ bridges that gap.
We build infrastructure that makes it simple for any team to discover their cryptographic exposure, adopt hybrid cryptography that combines classical and post-quantum algorithms, and enforce quantum-safe policies across their entire stack — without rewriting application code.
What drives us
Security-first engineering
Every design decision starts with the question: does this make our users more secure? We don't ship features that compromise cryptographic integrity.
Transparency and trust
Cryptography demands trust. We publish our algorithms, audit our code, and are transparent about what we know and what we don't.
Pragmatic migration
We don't believe in rip-and-replace. PostQ supports gradual, safe migration paths with hybrid cryptography, canary rollouts, and automatic fallback.
Developer empathy
Complex cryptography should have a simple interface. We care deeply about API design, documentation, and the developer experience.
Our story so far

Build the future of cryptography
We’re a small, focused team of engineers and cryptographers building critical infrastructure for the post-quantum era. If that excites you, we’d love to hear from you.
