Architecture

An operating system for growth.

The company's data, the knowledge of its market and encoded business expertise, brought together in a single model and put to work on every decision. The engine reasons; the code computes; every figure can be proven.

Why a system

A general-purpose LLM knows the world. Cortex OS knows your business, your customers' needs, your market and the rules of your trade.

Manufacturing, distribution, services, SaaS, e-commerce: Cortex OS has already learned what drives many industries. It knows what moves a business like yours forward, and guides you through your strategic decisions.

01 · The stack

5 layers, 2 cross-cutting services.

Each layer has one role, and one only. The engine reasons and converses; whatever can be computed (maturity, question order, derived calculations, permissions) stays in deterministic, tested code.

02 · The company twin

A memory that proves itself.

147 business fact types, each one typed, tied to its source and versioned. Every write is chained to the previous one by a SHA-256 hash: the entire history can be audited end to end. A less reliable source never overwrites a more reliable one.

03 · The code computes, the engine converses

The engine writes nothing except through a contract.

It acts through 14 typed tools, each validated against a schema before it runs. It can declare, cite a source or estimate; the most reliable sources enter only through the code. A value can never look more certain than it is.

04 · Continuous learning

Every mission makes the system more expert.

The doctrine encodes expertise on 3 levels: Cortex OS, your advisory firm, your company. A rule observed across several companies becomes a candidate for the shared doctrine; an expert validates it; it then applies to all of them. A company's data, however, never leaves the company.
