Move your AI plan into operation

FenxLabs helps you assess, build and operate the model environment behind your applications and agents. Start with the engagement that matches the decision blocking you now.

Discuss your requirementsFind the one that fits your problem

Scoped to your requirements and quoted per engagement. Most engagements open with a paid proof of concept, deliberately small.

Start from the problem you actually have

Model Adaptation

A model shaped around your own data and workload, not a generic default.

A general-purpose model is trained for broad use. It has not seen your proprietary data, your specialist vocabulary or the way your organisation actually works.

Adapt a model around your data
  • Targeted fine-tuning, partial adaptation or full retraining
  • Open-weight models and other machine learning systems
  • Evaluated against your own tasks, not a published board
  • You keep the weights, and FenxLabs keeps no copy

We need evidence before choosing models and deployment.

Assessment and planning

Plan the model mix before you commit

We need to connect ARC without rebuilding every application.

Architecture and integration

How we connect it to your stack

No model on the market is good enough at our work.

Model Adaptation

Adapt a model around your data

We do not know which EU AI Act obligations apply.

EU AI Act readiness

Review EU AI Act readiness

We need FenxLabs to operate the live environment.

Managed Service

Explore the Managed Service
Choose one engagement or combine them. Scope follows the decision you need to make.

Know which offer you need

A specialist engagement, the FenxARC™ platform and the Managed Service solve different parts of the decision.

Specialist engagement

Assessment and planning, Model Adaptation and EU AI Act readiness can be bought without ARC. Architecture and integration connects ARC, so its deployment must be settled first.

ARC platform

ARC governs how users, applications and agents access models, tools and approved data sources. It does not govern an agent's reasoning, planning, application logic, runtime or business accountability.

Managed Service

FenxLabs assumes the agreed operational responsibility for ARC and the model environment, either inside your infrastructure or by hosting and operating it on your behalf.

Your models, data, routing intent and business accountability remain yours. FenxLabs owns only the operational responsibilities agreed for the engagement.
