PREQUANT
● SYSTEMS OPERATIONAL — EU + US

Software that keeps its secrets, even from quantum computers.

Prequant is an independent software studio. We don’t hand off at the demo: we design, build, deploy and operate complete products — secure messengers, web platforms, payment systems, AI pipelines — on servers we run ourselves, with post-quantum encryption as the default.

// FLAGSHIP — LEMNISCATE

A complete secure messenger, built from zero.

Lemniscate is an end-to-end encrypted messenger with calls, webinars and a creator economy — designed, developed and operated end to end by the team behind Prequant. It is the proof of what we can build for you.

  • ⬢
    Post-quantum, NIST level 5Two locks at once: ML-KEM-1024 (FIPS 203) plus classical ECDH P-256, content sealed with AES-256-GCM — the algorithm suite NSA’s CNSA 2.0 specifies for national-security systems. Recorded traffic stays unreadable, even for future quantum computers.
  • ⬢
    Keys never leave the deviceNon-custodial by design: private keys are generated and stored locally, the relay only ever sees ciphertext, and sealed sender hides who talks to whom.
  • ⬢
    Calls, webinars & live eventsPeer-to-peer encrypted voice and video that is never stored, group webinars and pay-per-view events with built-in ticketing.
  • ⬢
    Creator economy built inSubscriptions, paid channels, gifts and post boosts — creators keep 75% of every sale.
  • ⬢
    Its own blockchainA Proof-of-Authority chain with in-app coin wallet, PIN protection, escrow, token creation and a public explorer — private data never goes on-chain, only tamper-proof checksums.
  • ⬢
    Ephemeral & locked downDisappearing messages, view-once media, app lock, screenshot protection and authenticator-app 2FA.
  • ⬢
    Android, Windows & WebOn Google Play, in the Microsoft Store and in any browser — with signed over-the-air updates between releases.

// WHAT WE BUILD

One team, the whole stack.

Everything below is work we actually do in production — not a brochure list.

/01

Secure communication systems

White-label messengers and realtime platforms with post-quantum E2E crypto.

  • WebRTC voice & video, TURN infrastructure
  • Group chats, channels, presence, sealed sender
  • Hybrid ML-KEM-1024 + ECDH P-256 (NIST level 5)
  • Signed OTA update pipelines
/02

Web platforms & e-commerce

Complete platforms from first schema to checkout.

  • Shops, subscriptions, digital goods
  • Card payments (Stripe) & crypto payments with on-chain verification (Ethereum, Polygon, BNB)
  • Partner & multi-level affiliate systems with payouts
  • Admin backoffices, KYC flows, invoicing
/03

AI & automation

AI that ships output inside your business, not demos.

  • LLM agents & support chatbots
  • Content engines with human approval workflows
  • AI SEO: structured data, llms.txt, auto-indexing
  • Audio & media pipelines
/04

Mobile apps & stores

From codebase to a live listing users can install.

  • iOS & Android builds and releases
  • App Store / Play compliance (payments, review)
  • Over-the-air update systems
  • Push, deep links, store assets
/05

Infrastructure & operations

We run what we build — on hardened Linux we control.

  • Self-hosted mail (DKIM, DMARC, MTA-STS, deliverability)
  • Docker, nginx, PostgreSQL, zero-downtime deploys
  • DDoS/WAF, fail2ban, rate-limiting, audits
  • Encrypted backups, monitoring, alerting
/06

Realtime data & finance-grade systems

Systems where every row has to add up.

  • Own blockchains: Proof-of-Authority networks, token creation, explorers
  • Live websocket feeds & charting (candles, order books)
  • Wallet & ledger systems with reconciliation
  • 2FA flows, withdrawal protection, fraud guards
// SECURITY PRINCIPLES

Paranoid by profession.

01Post-quantum by defaultEvery new system ships with ML-KEM-1024 (NIST level 5) plus classical ECDH and AES-256 — the CNSA 2.0 algorithm suite. No “later”.
02Self-hosted onlyYour data lives on dedicated servers we administer — never in a shared big-tech cloud.
03Minimal data, minimal logsSensitive logs are kept in RAM, retention is short, and we collect only what the feature needs.
04Encrypted at restBackups are AES-256 encrypted before they touch a disk; keys never travel with the data.
05Hardened operationsFirewalls, fail2ban, rate limits, 2FA on critical actions — and we attack our own systems first.
06Standards, verifiedSPF, DKIM, DMARC, MTA-STS, DNSSEC, TLS everywhere — checked from the outside, not assumed.
// WHY “PREQUANT”

Harvest now, decrypt later is already happening.

“If your data must still be private in ten years, it has to be protected today.”

Encrypted traffic is being recorded right now, to be decrypted the day quantum computers are strong enough. Classical encryption alone cannot survive that day — lattice-based post-quantum cryptography can. That is why everything we ship is protected in advance: pre-quantum.
