Pietarien builds breakthrough things — and engines for others to do the same

Engine 01 — Nexus AI

Nexus is a complete AGI operating system: a self-evolving digital organism with constitutional ethics at the silicon level. Enterprise AI infrastructure, scoped to your operational reality. POPIA-compliant and loadshedding-resilient, built for South African operations.

• Nexus AI — Overview of the 12-layer Nexus Stack, deployment tiers, and capability partnerships.
• Nexus Personal — Sovereign AI companion for executives and professionals: second brain, career simulations, verifiable capability profile, local-first AI.
• Nexus Business — Autonomous operational brain: 38+ agents, loadshedding-proof, POPIA-compliant.
• External portal: nexus.pietarien.com — deep technical architecture.

The Nexus Stack — 12 layers

• DNA/Genome (constitutional identity), SovereignBus (event-driven message bus), Guardian Agent (autonomous oversight), CUTR Engine (cognitive unification and temporal reasoning).
• Constitutional DAG (mathematically unjailbreakable ethics), Pietarien Factory (540+ skills, autonomous agent spawning), 7-Tier Economic Router (85–95% API cost reduction), Poincaré Cortex (hyperbolic reasoning geometry).
• Blackboard Memory (shared cognitive workspace), Coherence Pulse (synchronisation), Health Monitor (self-diagnostics), PresenceGate (identity and access).

Deployment tiers

• CEREBRUM — desktop and workstation deployment.
• CORTEX — mobile and GrapheneOS deployment.
• BRAINSTEM — edge deployment on Raspberry Pi 5 class hardware.

What we do for companies

• Mining operations — autonomous digital twin with constitutional governance, predictive logistics and EnergyOS integration, 10th Man Protocol safety oversight, OfficeOS automation.
• Professional services — sovereign second brain with local-first data, career simulation and capability portfolio, client intelligence without cloud dependency.
• Manufacturing and logistics — real-time operational intelligence, multi-agent workflow orchestration, predictive maintenance and resource optimisation.
• Governance and institutions — transparent decision-making infrastructure, citizen-centered protocol design, constitutional AI alignment.

Modular capabilities include the Innovation App (21 adaptive tools) and the Business Stack automation templates. Engagements begin with a Capability Assessment.

Engine 02 — Pieta

Anti-collapse engine for hard problems. Pieta forces AI models to disagree, then grounds survivors against reality — whether that's 8,431 real patents and actual physics, or machine-checkable proofs and formal verification. What survives is structurally novel: patentable mechanisms, or provable theorems.

Two modes. One engine. Same rigor. Problem Solving mode: the Birch–Swinnerton-Dyer conjecture over function fields — one of the Clay Millennium Prize Problems — with a certified curve factory (2,937 curves), verified results (+30% idea-quality lift; pilot model at 98.4% accuracy in its certified domain; generator passing 20/20 exact-match tests against published mathematics; first refined-BSD certificate via SageMath + PARI), and the first commercial certificate service for computational mathematics. External: bsd.pietarien.com.

• 97.9% survival rate when the system eats its own output
• 1,800+ validated artifacts generated to date
• $4.14 total LLM spend per 25-book batch
• 13 patent-ready mechanism blueprints

Offerings: patent-ready blueprints, anti-collapse training data for LLM labs, doctorate-level physics validation against 791 EPO patents, and cross-domain hypotheses across 32 domains with full audit lineage.

• MiningOS — AI-driven mining dewatering and autonomous operations platform.

Engine 04 — Labs

Applied research portfolio: patent-pending systems under active development, priority dates established, partnerships under mutual NDA.

• Labs Engine 4 — 43 cross-pollinated ideas — 43 survivors reviewed by four independent judges and advanced through File, Build or Paper tracks. Public examples include a current-map-encoded fuel cell bipolar plate, ratchet-bolt overload counter and infusion pulse-dampening micro-accumulator. Explore the Engine 4 overview.
