Custom AI agents

Custom AI agent development for mid-sized and enterprise companies

We develop AI agents for companies with their own processes, several systems to connect and strict rules on data. The agent answers from your documents using retrieval-augmented generation (RAG), acts in your ERP and CRM with the right permissions and leaves important decisions to a person. It runs in an EU cloud or on your own servers.

When an off-the-shelf product is not enough

The SaaS does not talk to your systems

It looks good in a demo, but cannot read from your ERP or write to your CRM.

Data that cannot leave

Contracts, customer data and projects cannot go to a service whose location you do not control.

Answers without sources

An assistant that does not cite the document behind its answer is not usable in a structured company.

No way to verify it

Without logs and tests no one knows how often it is wrong, so no one trusts it.

When you need a custom agent (and when SaaS is enough)

We will be the first to tell you if an off-the-shelf product fits.

SaaS is enough if…

the case is standard, data is not confidential, no integration with internal systems is needed and volumes are low.

You need a custom agent if…

it must read and write in ERP, CRM or document systems, data must stay in the EU or in-house, and you need per-user permissions, logs and testing before production.

Architecture: model, data, tools, control

Model

Chosen for the case: provider APIs with EU data processing, or an open-weight model installed on private servers.

Data (RAG)

The agent searches your documents and answers from them, citing the source. Fine-tuning, i.e. retraining the model, is rarely needed: we propose it only when the case calls for it.

Tools

The actions the agent can take: read an order, create a draft, open a ticket. Each with its own permissions.

Control

Human approval on important actions, a log of every operation, thresholds beyond which the agent stops.

Integrations

ERP and Odoo

Read and write via API or database, with dedicated service users.

CRM

Contacts, deals, activities and customer history.

Document management and file shares

Documents indexed with their original permissions.

Microsoft 365 and Google

Email, calendars, shared files.

Databases and internal APIs

Any system that exposes data in a controlled way.

Evaluation before production

An agent goes live when the numbers say so, not when the demo looks convincing.

1

Test set

Real cases with known correct answers, hard ones included.

2

Metrics

Correct answers, hand-overs to a person, timings, cost per operation.

3

Abuse testing

Attempts to push the agent outside its rules: off-topic requests, instructions hidden in documents.

4

Logs and regression checks

Each release is compared with the previous one on the same test set.

Governance and the EU AI Act

We help on the technical side. For legal aspects, involve your own counsel.

Your role: deployer

An organisation using an AI system in its business is a deployer. Since 2 February 2025 it must take AI literacy measures for staff (Article 4).

Transparency (Article 50)

Since 2 August 2026, if the agent talks to people, it must disclose that it is AI, unless obvious.

High risk only in specific cases

Obligations for high-risk systems in Annex III (employment, credit, education, biometrics) apply from 2 December 2027, after the postponement in Regulation (EU) 2026/1744.

Logs and oversight

Operation log, a named responsible person, a procedure to suspend the agent.

Custom AI agents: frequently asked questions

Almost always RAG: the agent searches up-to-date documents and cites the source, and changing an answer means changing a document. Fine-tuning suits very specific styles or formats, costs more and needs care with any personal data used.
Yes. Open-weight models can be installed on your own hardware. They need suitable hardware and maintenance: we assess together whether the extra control is worth the cost.
By having it answer only from retrieved documents, asking it to cite sources, making it stop when nothing relevant is found and measuring errors on a test set before every release.
The company using it remains responsible for decisions. That is why actions with consequences, such as confirming an order or replying to a complaint, go through a person. For contractual aspects, consult a lawyer.
It depends on the number of systems to connect, the volume of documents, usage and where the model runs. We quote after the free review, with set-up and running costs shown separately.
Monitoring, updates to models and integrations, and regular review of the cases where the agent stopped. Response times and terms are set in the contract.

Free review: what to automate with AI

Point us to a repetitive task: incoming email, documents, data entry. We check whether an AI agent can handle it, with which human checks and with data kept in the EU.

  1. Leave your emailEverything else is pre-filled: just tap the areas you care about.
  2. We call you back within one working dayWe book a 30-minute video call, no commitment.
  3. You get a written noteWhat to do, in which order and the likely cost range.

All we need is your email

We write the message from the areas you tap. A person on our team replies.

Check the address: the @ or the domain is missing.

What should we review? Tap one or more areas (optional).

Free and with no commitment. We use your data only to reply: privacy notice.

Thank you , we have received your request.

We will email you within one working day to book the 30 minutes. If it is urgent, message us on WhatsApp.
