The verdict in three sentences
In Luxembourg, a bank's head of real estate, a family office or a fund manager looking for advice on an office lease or acquisition increasingly asks AI assistants like ChatGPT first, and the answer keeps only a handful of firms. Being named depends on consistent public information in French, English and German, factual expertise pages and credible third-party mentions (business press, market research, professional associations). This work is still an emerging market, typically priced at EUR 2,500 to 7,000 a month in 2026, and it should be judged on a dated record of the answers to the same questions, never on a promise.
What decision makers ask AI assistants about Luxembourg commercial real estate
The questions mix district, floor area, timing and language. An advisory that only exists publicly in English often vanishes from answers given in French or German.
| Question asked to an AI assistant | Who is asking | What the answer draws on |
|---|---|---|
| Which independent advisor can represent a tenant for 3,000 sq m of offices in Kirchberg? | Head of real estate at a bank | Tenant representation pages, public references, press mentions |
| Should a 200-person headquarters move to Cloche d'Or or Gasperich? | CFO of an international group | Published market studies, district analyses |
| Who advises a fund on acquiring an office building in Luxembourg? | Real estate fund manager | Investor advisory pages, team, transactions made public |
| Which firms publish quarterly reports on the Luxembourg office market? | Analyst, investor | Dated reports, business press citations |
| Welches Beratungsunternehmen hilft bei der Suche nach Büroflächen in Luxemburg-Stadt? | German company setting up | German-language pages, consistent directory listings |
| How do you renegotiate a commercial lease before it expires in Luxembourg? | Office manager, SME CFO | Published guides, FAQs, expert articles |
| Which environmentally certified buildings are available in Belval? | Head of sustainability | Real listings, sustainability pages |
These answers shape the first impression of a client who has never called you. Better to know what they say.
Why one firm gets named and another is ignored
AI assistants like ChatGPT summarise what is written publicly. In a market as small and international as Luxembourg, any inconsistency between languages or sources weighs heavily.
| Factor | Effect on answers | Frequent gap |
|---|---|---|
| Consistent public information | Same name, address, partners and service lines everywhere | Old Limpertsberg address in a directory, team page only current in English |
| Factual expertise pages | One page per service (tenant representation, investment, valuation) with scope and approach | Vague overview pages with nothing verifiable |
| Presence in the three business languages | Answers possible in French, English and German | Single-language site or rough machine translations |
| Third-party mentions | Business press citations, conference talks, research picked up by others | Firm invisible outside its own site |
| Real listings and transactions | Concrete public examples that anchor expertise | Expired listings still online |
| Structured data and freshness | Machine-readable details, dated reports | Last market report published two years ago |
On compliance, the GDPR applies and the CNPD is the supervisory authority in Luxembourg, so contact forms collect only what is needed. Real estate agency activity requires a business permit, and anything you publish about transactions must respect your confidentiality commitments. This is not legal advice.
What the work covers and what it costs
In broad terms: an initial record of what AI assistants say about the firm and its competitors, aligning public information in each language, strengthening expertise pages and research content, earning credible mentions, and regular tracking. It overlaps with SEO but is measured differently.
| Type of engagement | 2026 ballpark | Usual content |
|---|---|---|
| One-off diagnostic, one language | EUR 3,000 to 6,000 | 30 to 40 questions, accuracy of answers, priorities |
| One-off diagnostic, three languages | EUR 5,000 to 10,000 | Same scope in French, English and German |
| Monthly program, independent advisory | EUR 2,500 to 4,500 per month | Content, listings, monthly answer tracking |
| Monthly program, office of an international network | EUR 4,500 to 7,000 per month | Coordination with group marketing, more languages and pages |
| PR and research distribution | EUR 3,000 to 12,000 per campaign | Pitching a market report to business media |
These ranges are prudent and come from typical European agency quotes and public rate pages; the market is young and offers differ widely. Kolonell prices this work on quote, and no one can guarantee that an AI assistant will recommend a firm.
Measuring: a dated log, not a feeling
The only reliable indicator is a log: the same question list, asked every month in each language, with answers archived and dated. It shows the share of answers naming the firm, the accuracy of what is said (partners, services, address) and where the firm sits in the answer. Six months of records is a minimum, since answers fluctuate from one session to the next.

Mini case study
Illustrative example: "Kirchberg Workplace Partners", eight consultants focused on tenant representation. A dated record of 45 questions (15 in French, 15 in English, 15 in German) shows the firm named 6 times, a 13% share (6 ÷ 45 = 0.13), and never in German.
Budget considered: a three-language diagnostic at EUR 7,000, then six months at EUR 3,500 (market assumption), a total of 7,000 + 6 × 3,500 = EUR 28,000. If a tenant representation mandate earns EUR 40,000 in fees on average (market assumption), a single additional mandate traced to these channels covers the spend. The firm sets its rule in advance: a higher share of mentions in German and no address errors after six months, otherwise it stops.
FAQ
Do AI assistants like ChatGPT answer differently depending on the language?
Yes, often. A firm well described in English can be missing from answers in German or French, which is why a three-language diagnostic (EUR 5,000 to 10,000 on the market) tells you more in Luxembourg.
Can we publish our transactions to be named more often?
Only those already public or that the client has cleared for publication. Two or three factual, authorised examples beat a long unverifiable list.
How long before a measurable effect?
Usually 3 to 6 months between corrections and a visible change in the log. Answers fluctuate, so measure on 30 to 45 questions rather than two or three.
Does this replace SEO?
No, it complements it. Clear pages and structured data serve both, but here the measurement is about answers and their accuracy, and business press mentions carry more weight.
What does a first diagnostic cost?
On the market, EUR 3,000 to 6,000 for one language and EUR 5,000 to 10,000 for three. Kolonell quotes it based on the number of questions and languages.
