● 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.

  • ⬢
    True end-to-end encryptionMessages, media and calls — hybrid ECDH + ML-KEM key exchange, so recorded traffic can’t be decrypted later.
  • ⬢
    Calls, webinars & live eventsEncrypted voice and video, group webinars and pay-per-view events with built-in ticketing.
  • ⬢
    Creator economy built inSubscriptions, channels, gifts and post boosts — creators keep 75% of every sale.
  • ⬢
    Integrated coin walletIn-app currency with PIN protection, escrow for gifts and swaps to premium features.
  • ⬢
    Private by designSign-up with e-mail only — no phone number required. Runs exclusively on our own EU and US servers.
  • ⬢

// 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
  • Hybrid ECDH + ML-KEM handshakes
  • 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.

  • Live websocket feeds & charting (candles, order books)
  • Wallet & ledger systems with reconciliation
  • 2FA flows, withdrawal protection, fraud guards
  • High-volume background job pipelines
// SECURITY PRINCIPLES

Paranoid by profession.

01Post-quantum by defaultEvery new system ships with hybrid classical + ML-KEM lattice cryptography. 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.
