The problem

Enterprise AI is broken today

Five failures that feed each other, locking enterprise AI in a vicious circle with no way out.

The idea

Add a reasoning layer

Think of it like a mind. The LLM is the senses: eyes and ears that translate messy human language into meaning. ReasoningLayer is the brain that reasons over your facts, rules, and logic to reach a provable answer.

The senses
LLM · eyes & ears
Reads language, intent, and ambiguity, then translates the messy real world into structured meaning.
The brain
ReasoningLayer
Thinks it through. Applies your facts, rules, and logic to reach a correct, provable answer, then shows its work.
How it works

From your data to a proven answer

1

Connect

Plug into your APIs, databases, and documents, wherever your data already lives.

→
2

Unify

Auto-extract and merge it all into one knowledge base. Scattered data becomes structured knowledge.

→
3

Reason

The model interprets intent; the symbolic engine checks every step against that knowledge.

→
4

Prove

You get a verified result, with a complete, auditable trail of how it was reached.

Why ReasoningLayer

Beyond search and grounding

// today
Plain LLM
Guesses from patterns. No grounding in your data, no proof, no guarantees.
// better
RAG & search
Retrieves text chunks to stay on topic. Closer, but still no logic and no certainty.
// reasoning
ReasoningLayer
Grounds your data and reasons over it. Applies your rules and proves every answer. Grounding is the base; reasoning is the edge.
What you can build

Build agents you can trust to act

// assistants

Grounded copilots & voice agents

Real-time assistants that answer only from your own data, never from guesswork.

// search

Explainable RAG

Search and answers that ship with citations and a verifiable proof trail.

// decisions

Autonomous decisioning

Claims, eligibility, and pricing, decided by your rules with a full audit trail.

// guardrails

Policy & compliance guardrails

Enforce your business rules and the EU AI Act on top of any model.

Industries

Built for high-stakes, regulated work

// cybersecurity
“Is this alert a real policy violation, and which rule proves it?”
// healthcare
“Does this recommendation follow the clinical protocol, with proof?”
// insurance
“Is this claim covered, and exactly why?”
// banking & finance
“Does this case satisfy every compliance rule?”
// public & legal
“Is this decision auditable, end to end?”
Reliability
Reliability

Reliability you can prove

Grounded in your truth
Every answer is checked against your knowledge base and business rules before it ships.
Deterministic by design
Symbolic reasoning is reproducible. The same input always produces the same answer.
Built for messy reality
Fuzzy and temporal logic handle uncertainty, partial matches, and change over time.

The guardrail

Stop hallucinations from becoming actions

LLM
Proposes the answer or action. Fast and fluent, but sometimes wrong.
→
ReasoningLayer
Checks every step against your facts, rules, and logic before anything runs.
→
✓
Grounded
The action executes, provably correct.
✕
Unsupported
Caught and blocked before it ever acts.

ReasoningLayer
Your data + your licensed engine
Stays inside your perimeter. We never see it and never train on it.
We license software, not your data
Your data, model, and rules remain your property. We're not in the data business, unlike big-tech AI.
Licensed, not locked in
Run it on-premise or in your own cloud, on ordinary CPUs. No GPUs, no retraining bills.
Tuned to your domain
Auto-modeled to your business, so the engine reasons like an expert in your field.

Lower cost, deeper reasoning

Beat the context limit

Your knowledge lives in the reasoning layer, not the prompt. The model only ever sees the few facts each question actually needs.

Replace a fragmented stack

Knowledge graph, constraint solver, authorization, and extraction, all consolidated into one platform.

Scale without the spike

Reasoning runs on your terms, not per-token, so growth no longer means a runaway bill.
