◇ About · Qubble Labs
A small team building in the open,
one surface at a time.
Qubble Labs builds cryptographic infrastructure that is designed to survive the arrival of a cryptographically relevant quantum computer. We ship one surface at a time, prove the principles on each, and let the work compose into the larger thing it is meant to be.
§ 01 · Mission
The internet's confidentiality layer needs to be re-keyed before a quantum computer is fielded that can break it.
That re-keying is happening — slowly, partially, mostly in places that already had budget for cryptographic projects. The places that didn't, which is most of the internet, are exposed. Captured TLS sits in storage right now, waiting for the cryptanalysis it was always going to receive.
We build the surfaces that do not require re-keying — because they were designed without the asymmetric primitives that Shor's algorithm breaks — and we adopt the NIST PQC suite, slowly and with audit, where public-key behaviour is genuinely required. The work is for the long arc.
§ 02 · How we work
Build a surface. Prove the primitives. Let it compose.
01 · Surface by surface
Each surface we ship is end-to-end. It is small. It is auditable in isolation. It composes onto the same cryptographic core, and is replaced only when the work itself proves replacement is warranted.
02 · Code over copy
If a property cannot be verified by the user, we do not claim it. Cryptographic claims are technical claims; they are stated so that they can be falsified.
03 · Slow on purpose
The product velocity is intentional. The downside of moving fast on cryptographic infrastructure is not bugs — it is invariants that cannot be recovered after the fact. Slow is part of the design.
§ 03 · The team
Small, named, accountable.
Builds the surfaces. Owns the cryptographic decisions. Answers hello@qubblelabs.com personally during the early stretch.
The team grows when the work requires it. Contributors are named as they ship. We don't carry vanity headcount.
§ 04 · A note on what this is for
We are building infrastructure for people who deserve privacy.
Privacy is load-bearing in a free society. Journalists protecting sources, activists in authoritarian states, lawyers and their clients, doctors and their patients, ordinary people whose ordinary business is none of anyone else's — they are the legitimate population we are building for.
We are aware that the same primitives can be put to ugly use. We will cooperate with lawful process where we are technically and legally able to. The architectural choice to hold no key material on our infrastructure is deliberate; it limits what we can be compelled to produce, and it also limits the harm of any breach.
That tension is real. We don't pretend it isn't.
