The encryption protecting your data today has an expiry date.

Codesstellar builds the post-quantum infrastructure that replaces it, and the AI systems that run on top. Lattice cryptography standardised by NIST, implemented properly, running in production.

What changes when you work with us

Talk to an engineer

You talk to the people writing the code

There is no account management layer between you and the build. The engineer on your discovery call is the engineer shipping your system.

Your cryptography is standards based

NIST FIPS 203 and FIPS 204 primitives implemented against liboqs, with a documented migration path from RSA and ECDSA. Nothing invented in house.

Every AI system ships with an evaluation harness

A measured baseline, a defined failure mode, and a way to tell whether the model is still working six months after launch.

You own the result

Source, infrastructure, model weights where applicable, and written documentation transfer to you at handover. No lock-in, no licence trap.

What we solve

Four problems keep turning up in the rooms we sit in. Each one has a product behind it that already runs.

Data encrypted today is being collected today and decrypted later.
Q-Vault
Quantum safe storage and transport. ML-KEM key exchange, ML-DSA-87 certificate chains, AES-256-GCM at rest, exposed over gRPC and HTTP.
You cannot prove the face in front of the camera belongs to a living person.
AmFatec verification engine
3D liveness, face matching, deepfake detection and document forensics, with the biometric payload encrypted under post-quantum key exchange.
An audit trail is only as trustworthy as the signature scheme beneath it.
Q-AmChain
A post-quantum ledger where every block and transaction is signed with ML-DSA-87, with a full block explorer and a dual signing wallet.
Your team spends its week on work a model could do correctly.
Applied AI systems
Computer vision, speech, retrieval augmented assistants and decision intelligence, built against your data and measured before release.

A few things we have built

Every screen below is our own software, running. Not a mockup.

Post-quantum infrastructure

Q-AmChain and the QB Cure wallet

A layer one chain built as a trust and audit substrate rather than a currency. Validators sign with ML-DSA-87 under a post-quantum BFT consensus, paired with a block explorer and a wallet that signs for both the post-quantum chain and standard EVM networks from one interface.

Secure storage

Q-Vault

A hybrid C++ and Python backend for quantum safe storage and communication, deployed for a data centre operator. Machines authenticate with post-quantum certificates rather than passwords, and the console reports the live posture of every layer.

Biometrics

AmFatec verification engine

Face verification and 3D liveness with no depth sensor required. Changing distance across a 64 frame burst separates a living face from a photograph or a screen, and the frames are bundled, signed and encrypted on the device before anything leaves it.

Strike Analytics

Pose estimation from ordinary camera footage, tracked in three dimensions. Punch counting, reaction time, and form scored frame by frame against a reference skeleton, so a coach can see exactly where the technique drifts.

Conversational AI

Salon chat bot and operations platform

Booking, memberships, staff scheduling and payments behind one dashboard, with a conversational agent that handles enquiries, recommends services from customer history, and writes the booking straight into the diary.

Alongside these sit voice cloning, volumetric capture, retrieval augmented assistants, and mobile and web platforms shipped across twelve countries. See the full catalogue

How an engagement runs

Four stages, each with something written at the end of it. You always know what you are paying for before you pay for it.

Stage 1

Discovery

A working call with an engineer. We map the problem, the constraints, the data you already hold, and what success has to look like.

45 minutes, no charge
Stage 2

Written scope

A document covering architecture, deliverables, milestones and a fixed fee. If the scope is wrong, we would rather find out here.

Within five working days
Stage 3

Build

Two week increments with a working artefact at the end of each one. Direct access to the team throughout, in your channel of choice.

Reviewed fortnightly
Stage 4

Handover

Deployment, documentation, a walkthrough for your engineers, and an agreed support window. The system is yours to run.

Support window agreed upfront

Who we work best with

We would rather say no early than disappoint you late, so here is the honest version.

A good fit

Where we do our best work
  • Teams facing a cryptographic migration deadline, whether that is CNSA 2.0, a regulator, or a customer security questionnaire.
  • Founders whose product has a genuinely hard technical core rather than a thin layer over an existing API.
  • Institutions in government, health, finance or critical infrastructure keeping data confidential for longer than a decade.
  • Companies who want to own the intellectual property outright and run the system with their own people afterwards.
Recognise your situation here? A discovery call is the quickest way to confirm it. Book a consultation

Probably not a fit

Where someone else will serve you better
  • A brochure website or a template build needed inside a fortnight.
  • Work awarded purely on the lowest hourly rate.
  • A model demonstration with no intention of putting it in front of users.
  • Projects where the requirements are expected to be discovered entirely by us without access to your team.
Not sure which side you fall on? That is what the discovery call is for. Book one and find out

Questions we get asked

The six that come up in almost every first call.

Not answered here?

Send the question with a little context and an engineer will answer it directly, not a sales team.

Ask an engineer
Is post-quantum cryptography actually necessary yet?

The threat is not that a quantum computer breaks your traffic tomorrow. It is that encrypted traffic captured today can be stored cheaply and decrypted once one exists. If your data has to stay confidential for ten years or more, the migration decision is already live. The NSA has set January 2027 as the point at which new national security systems must support CNSA 2.0 algorithms.

Do we have to replace our whole stack?

No. Most migrations are hybrid: classical and post-quantum algorithms run side by side so that nothing breaks if one is later found weak. We normally start with key exchange on the most sensitive channel, then signatures, then storage. The written scope sets out that order for your systems specifically.

How do you price work?

Fixed fee against a written scope, milestone based. Long running platform work moves to a monthly retainer once the initial build is handed over. We do not bill by the hour, because it rewards the wrong thing.

Who owns the code and the models?

You do, on handover, including source, infrastructure definitions and documentation. Where we bring an existing product such as Q-Vault or Q-AmChain, that is licensed to you on terms agreed before the build starts, and we say so plainly in the scope.

Can you work with our existing engineering team?

Yes, and it usually produces a better result. We can lead the build with your team embedded, or take a defined component while your team owns the rest. Handover is smoother when your engineers have been in the repository the whole time.

What does a first conversation involve?

Forty five minutes with an engineer, not a salesperson. Bring the problem, any constraints you already know about, and whatever you have tried. You will leave with a point of view on the approach whether or not you work with us.

Tell us what you are trying to build.

Answer a few questions and the right engineer will come back to you, usually within one working day.
