How much does a private AI cost for an SME in Luxembourg in 2026?

You run a Luxembourg SME and you want to put a figure on a private AI project? Here is the direct answer, up to date as of July 2026. On the market, setting up a private AI hosted in Europe ranges from around €1,500 for a website chatbot to €20,000 for a full phone agent, with a monthly subscription added on top. But that headline price is not your real cost. In Luxembourg, the SME Packages AI and Digital programs reimburse up to 70% of the investment, capped at €17,500 of aid per project (source: guichet.lu). A €15,000 setup project therefore comes down to €4,500 once the grant is applied. The real question is not "how much does it cost", but "what is my net cost after grants". That is exactly what this article breaks down, solution type by solution type. First useful clarification: a private AI is an artificial intelligence model deployed for your organization alone. On that basis, a private AI for businesses keeps your data in-house rather than on a third-party platform.

Why prices vary so much

If you have already requested quotes for an AI project, you probably received proposals ranging from a few hundred euros a month to several tens of thousands of euros. That spread is not abnormal. It comes down to three fundamental variables.

What you want to do with it

A chatbot that answers frequently asked questions on your website does not require the same work as an internal assistant able to search through 10,000 documents to find a precise contract clause. And an AI phone agent that answers your calls around the clock requires yet another kind of infrastructure (speech recognition, speech synthesis, call scenario handling).

The more complex the use case, the higher the cost. But "complex" does not mean "expensive". A well-configured AI chatbot on your website can be up and running in a few days. An internal document assistant requires a more substantial effort to integrate your documents.

The number of users

For internal solutions (an AI assistant for your teams), the price generally scales with the number of users. Not linearly: the first users cost more per head (the setup has to be amortized), then the cost per user drops. Most providers offer per-user licences whose price varies according to volume and the level of server pooling.

The volume of data

If you want your AI to be able to answer by drawing on your own documents (contracts, procedures, guides, FAQs), they need to be integrated into the system. This step, known as "indexing" in technical jargon, has a cost that depends on the volume of documents and their complexity (a scanned PDF is not processed like a structured Word document).

The billing models

The private AI market for SMEs has settled around two main billing models. In both cases, an initial setup cost is unavoidable: your documents have to be indexed, the scenarios configured, the AI tested on your real cases, and your teams trained. That initial work is what makes the difference between a supported premium solution and a tool you configure on your own.

1. The upfront setup fee and monthly subscription

This is the most common model for premium solutions. A setup cost for the full configuration (indexing your documents, testing, customization, training your teams), then a monthly subscription for hosting, maintenance, and support.

The advantage is clarity. The initial cost is fixed, the recurring cost is predictable. You know exactly what you are paying. The provider supports you from A to Z.

2. Usage-based billing

Some solutions bill according to consumption: number of conversations, number of queries, volume of data processed. This model is attractive at first (when usage is low) but can become unpredictable once internal adoption takes off.

The question to ask: "What will my monthly cost be if each of my 30 employees uses the tool 20 times a day?". If the provider cannot give you a clear estimate, be wary.

Whatever the model, remember that the cheapest solutions are often the ones where you do everything yourself: configuration, document indexing, testing, training. For an SME with no technical profile in-house, support from a specialist provider is an investment that avoids weeks of trial and error.

Price ranges by solution type

Here are the price ranges observed on the European market in 2026 for SMEs of 10 to 50 people. These figures are orders of magnitude seen on the market, not a rate card: every project is quoted individually. They cover 100% sovereign solutions, hosted and processed in Europe. Solutions using American APIs exist at slightly lower rates, but with trade-offs on GDPR and data sovereignty. Keep in mind that these amounts are before grants: your real net cost is calculated after the SME Packages.

AI chatbot for your website

The chatbot answers your site visitors, qualifies prospects, answers frequently asked questions, and can book appointments.

Setup: from €1,500 to €8,000 depending on complexity (number of scenarios, integration with your CRM, multilingual support FR/DE/EN/LB).

Recurring cost: from €150 to €500 per month for hosting, maintenance, and conversation volume.

Setup time: 1 to 3 weeks.

Internal AI assistant (knowledge base)

Your employees ask the AI questions and it answers by drawing on your internal documents: procedures, template contracts, technical documentation, business guides. The documents stay on European servers and never pass through third-party platforms. That is the principle of a private AI: your data stays yours.

Setup: from €10,000 depending on the volume of documents to integrate, the number of sources, and the level of customization. This cost includes indexing your documents, configuring access rights, testing, and training your teams.

Recurring cost: between €50 and €150 per licence per month, depending on the number of users and the level of server pooling. Important: pooled servers does not mean less secure. Each company has its own partitioned space and its data is strictly compartmentalized. It is the same principle as web hosting: you share the physical infrastructure, but your data is isolated from that of other clients.

Setup time: 2 to 6 weeks.

AI phone agent

The AI answers your calls, understands the request, responds or transfers to the right person. It works around the clock, in several languages.

Setup: from €5,000 to €20,000 depending on the number of call scenarios, the languages supported, and the integrations (calendar, CRM, ticketing system).

Recurring cost: from €200 to €800 per month, plus a per-minute conversation cost that varies with volume.

Setup time: 3 to 8 weeks.

Combined solution (chatbot and internal assistant)

Most SMEs end up combining a customer-facing chatbot with an internal assistant. It is often the best value for money, because part of the integration work (document indexing, configuration) is shared between the two solutions.

Setup: from €10,000 to €15,000 for a 100% sovereign solution. Slightly less if some components use American APIs (which work very well technically, but raise GDPR compliance questions).

Recurring cost: the chatbot cost (€150 to €500/month) plus the internal assistant licences (€50 to €150 per user/month).

Comparison: public AI licences vs private AI

Before looking at the figures, an important clarification: comparing the price of a ChatGPT licence to that of a private AI is like comparing the price of a free Gmail account to that of a corporate email server. The product is not the same, and above all the guarantees are not the same.

* ChatGPT Team and ChatGPT Enterprise are now accessible to modestly sized teams: OpenAI has removed the seat minimum historically tied to the Enterprise offer, and ChatGPT Team can be subscribed from just a few users (around €25 to €30 per user/month depending on an annual or monthly commitment). Public pricing: openai.com/chatgpt/pricing.

** This cost includes the internal assistant user licences. The customer-facing chatbot is a separate cost (€150 to €500/month). The SME Packages grants can significantly reduce the initial setup cost.

One point deserves clarifying, because it changed recently. OpenAI now offers European data residency for its Team, Enterprise, and API plans: technically, your data can be stored on European servers. That is a genuine improvement. But data residency is not legal sovereignty. OpenAI remains a company under American law, and therefore subject to the CLOUD Act: a US authority can legally demand access to data held by the company, including when that data is hosted in Europe. The same reasoning applies to Microsoft Copilot. For a Luxembourg SME bound by professional secrecy, European hosting is therefore not enough: what matters is that the provider and the infrastructure fall under European law. That is the lasting difference between an AI "hosted in Europe" and an AI that is truly sovereign.

The key point: yes, a private AI costs more per month than ChatGPT Plus or Team licences. But you are comparing an AI trained on your documents, hosted in Europe and under European law, with local support, to a generic tool whose publisher remains subject to American law. For a Luxembourg SME bound by professional secrecy, the question is not "is it more expensive?" but "can I afford not to control the legal framework that protects my clients' data?". That is why choosing a private AI goes beyond a simple price comparison, and it is also the subject of our article ChatGPT at the office: is it a risk for your business?.

The hidden costs not to forget

Beyond the headline price, several costs are often underestimated.

Training your teams

Your employees have to learn to use the tool. It is not complicated, but it takes time. Count on half a day of initial training for the whole team, then light support during the first few weeks. Some providers include this training in the initial fee. Others bill it separately (count on €500 to €2,000).

Since February 2025, Article 4 of the EU AI Act imposes a training obligation for anyone using an AI system in a professional context. This training is therefore mandatory in any case.

Evolving maintenance

Your business changes. Your procedures evolve. Your documents get updated. The AI has to keep up. If your provider bills every update of the document base as a new project, the invoice can balloon quickly. Check that the contract includes a regular update mechanism within the subscription.

Integration with your existing tools

If you want the AI to connect to your CRM, your calendar, your ticketing system, or your ERP, that is additional development work. Simple in some cases (standard API), more complex in others (legacy business software with no API). Ask for a precise quote for each integration.

The cost of doing nothing

This is the most overlooked cost. While you deliberate, your employees are using ChatGPT for free, with no framework or oversight. The cost of a data breach, a GDPR fine, or a loss of client trust is infinitely higher than the cost of a private AI. For a Luxembourg SME whose model rests on confidentiality, a single incident can cost far more than years of a private AI subscription.

The grants available in Luxembourg

This is one of the concrete advantages of being based in Luxembourg. Two grant programs make it possible to significantly reduce the cost of an AI project.

SME Packages AI

The program dedicated to artificial intelligence projects. It covers up to 70% of the cost of an AI project for SMEs, for projects worth between €3,000 and €25,000 excluding VAT. Concretely, the aid is capped at €17,500 per project, that is 70% of €25,000 (source: guichet.lu).

This program offers simple, easy-to-implement initiatives to bring AI into your SME's processes. It helps companies assess their current AI situation and encourages the integration of existing solutions suited to their needs.

Conditions: hold a business permit issued by the Ministry of the Economy, meet the SME criteria (headcount, turnover, balance sheet), and have your registered office in Luxembourg.

The first step is to contact the House of Entrepreneurship of the Luxembourg Chamber of Commerce (or the eHandwierk service of the Chamber of Skilled Trades for craft businesses). They carry out a preliminary analysis and help you put together your application. For the details of the procedure, follow our guide to building your SME Packages AI grant application.

SME Packages Digital

This program covers digital transformation in the broad sense. It supports you in setting up digital tools to improve online communication with your clients and the management of your business. It covers three areas: digital marketing (creating or improving your website, social media campaigns), management systems (ERP, point of sale, business software), and electronic invoicing (a dedicated e-invoicing module).

The AI chatbot on your website, for example, can fall within the digital marketing scope of this program.

The two grants can be combined, but not on the same project

Important point: the SME Packages AI and Digital programs can be combined. But you cannot mobilize them simultaneously on a single project. Concretely, you can benefit from SME Packages AI for deploying your internal AI assistant, then from SME Packages Digital for overhauling your website with an integrated chatbot. Two distinct projects, two distinct grants.

Concrete impact on your net cost

Let's take an example: you want to deploy an internal AI assistant for your 25 employees.

Estimated setup cost: €15,000. After SME Packages AI (70%): €4,500 net cost. Monthly cost: around €100 per licence for 25 users, that is €2,500/month. But with pooled servers and a negotiated volume, this cost can be substantially reduced.

Six months later, you add a customer-facing chatbot on your website. Cost: €5,000. Eligible for SME Packages Digital (70%): €1,500 net cost. Monthly cost: €300/month.

Total of the two grants obtained: up to €10,500 plus €3,500, that is €14,000 covered. Your net cost at the investment stage drops to €6,000 for both projects, versus the €20,000 headline figure.

How to estimate your budget

Here is a simple method to estimate the budget for your AI project in four steps.

Step 1: identify your priority use cases

Do not try to do everything at once. Start with one or two high-impact use cases. For example: a chatbot for your website (if you receive a lot of repetitive questions) or an internal assistant (if your teams waste time looking for information in your documents). To identify the best use cases, see our guide to AI services to automate administrative tasks.

Step 2: put a figure on the time lost today

How much time do your employees spend each week answering the same questions? Looking for information in a document? Rephrasing emails? If 10 employees each save 30 minutes a day thanks to an internal AI, that is 25 hours a week. Valued at the average hourly cost, that represents a measurable gain.

Step 3: request several quotes

As with any investment, compare. Request at least two detailed quotes, checking that each proposal includes: the setup cost, the recurring monthly cost, what is included in maintenance, the cost of updating the document base, and any integration costs.

Step 4: factor in the SME Packages grants

Before comparing quotes, apply the grants. A €15,000 project that comes down to €4,500 after SME Packages AI completely changes the equation. Your provider should be able to support you with the grant application, and the House of Entrepreneurship is there to guide you through the process.

Conclusion

A private AI for a Luxembourg SME of 10 to 50 people is a setup investment starting from €10,000 on the market, brought down to a net cost in the order of €3,000 once the 70% grant is applied, plus monthly licences of €50 to €150 per user.

It is more than a ChatGPT Plus or Team licence, but the guarantees are incomparable: your data stays in Europe and under European law, the AI knows your documents, you have a local point of contact, and you are compliant with GDPR and Luxembourg professional secrecy. To frame your project, it is better to start from your use cases: here is how we structure a custom AI project.

The real cost is the cost of doing nothing. While you hesitate, your employees are sending your clients' data to servers whose publisher remains subject to American law, via free ChatGPT. Every day that passes is another day of risk.

FAQ

Is private AI only for large companies?

No. That was true two years ago, when deploying an AI required dedicated servers and a technical team. In 2026, turnkey solutions exist for SMEs of 10 to 50 people, with accessible budgets and setup times of a few weeks.

Why not simply use ChatGPT Team or Enterprise?

Today, it is technically possible: OpenAI has removed the seat minimum once required for ChatGPT Enterprise, and ChatGPT Team is accessible from just a few users (around €25 to €30 per user/month). So the entry price is no longer the obstacle. It lies elsewhere: even with the European data residency now offered by OpenAI, the publisher remains subject to American law (CLOUD Act), the AI is not trained on your specific documents, and Luxembourg professional secrecy is not guaranteed. For an SME handling sensitive data, a European private AI offers better sovereignty guarantees, while remaining eligible for the SME Packages grants that cut the bill by 70%.

Are the SME Packages programs complicated to obtain?

No. The first step is to talk with a specialist provider to understand your needs and define the scope of the project. Then it is the provider who puts you in touch with the appropriate body (House of Entrepreneurship of the Chamber of Commerce or the Chamber of Skilled Trades) to launch the grant application procedure. Conditions: being an SME based in Luxembourg with a business permit. The time to obtain it is a few weeks.

Do pooled servers mean my data is not secure?

No. Pooling servers means sharing the physical infrastructure, not the data. It is the same principle as web hosting: each company has its own partitioned space. Your data is strictly compartmentalized and inaccessible to other clients. Pooling makes it possible to reduce costs without compromising security.

How long does it take to recoup the investment?

For a customer-facing chatbot, the return is often immediate: less time spent answering the same questions, better responsiveness, leads qualified automatically. For an internal assistant, count on 1 to 3 months for adoption to become widespread. But beyond the time saved, the real return on investment is also measured in the quality of the answers. When the AI is powered by your best experts, every employee has access to answers at the same level as those of your most qualified people. Most SMEs see a return on investment in under 6 months.
