The problem

Your best data is exactly the data you can't give to AI.

Formulas, deal terms, pre-filing patents, process know-how: the decisions that matter most run on data that must not leave the company. So enterprises either block frontier AI — or quietly leak into it.

BLOCK

DLP & redaction

Filters strip what they recognize — and ship all remaining context to the cloud. What the classifier misses, leaks.

WAIT

Homomorphic encryption

Provably private, but orders of magnitude too slow and costly for LLM-scale reasoning. Practical hardware is years away.

SETTLE

Local models only

Data stays home — but local models can't match frontier reasoning on hard, high-stakes decisions.

Our approach

Transform, don't block.

A local model converts your confidential context into a semantically faithful but generic representation. The frontier model reasons on it — and never sees the real data.

1

Abstract — inside your walls

Confidential data and business context are transformed locally into a generic, semantically faithful task.

2

Reason — at the frontier

The world's best AI models reason on the abstract task and return an abstract recommendation.

3

Re-contextualize — locally

The answer is grounded back into your real data, on-premise: a decision, fully in context.

Enterprise boundary: steps 1 and 3 run inside your infrastructure. Inspired by homomorphic encryption — a structure-preserving transformation, reason(abstract(x)) ≈ abstract(reason(x)) — at practical speed instead of cryptographic cost.
