The sale file is finalised at midnight. The photos have been processed, the description written, the comparables analysed, the price range documented. The next morning, the property goes live. That pace was not sustainable ten years ago, and no more so for a human-scale agency determined to remain rigorous on every file. What artificial intelligence has changed in property brokerage is not the nature of the work: it is the speed of execution for tasks that lend themselves to it, and the depth of analysis possible for those that demand it. For an owner looking for an estate agency that genuinely uses AI — not merely the word — the useful question is not "do they have an algorithm?" but "what do they actually use it for, and who remains responsible for the result?"
That is the question around which Alexandre built Affinités Immobilier. The ambition can be stated in a single sentence: artificial intelligence for proof and speed, a broker for trust.
What the machine does better
A serious valuation requires comparing real, recent transactions within a coherent perimeter, taking into account floor area, storey, aspect, year of construction and general condition. Assembling that dataset by hand takes hours. Processing it to extract a defensible price range takes longer still. This is precisely where automated analysis tools add something: they scan a volume of data no broker could absorb alone in a reasonable time, and they do so in a reproducible way, without fatigue or shifts in mood.
The result, at Affinités Immobilier, is La Juste Mesure: a detailed valuation in which every comparable sale is displayed line by line, with its distance from the property being assessed, its characteristics and its price differential. The owner does not receive a figure pulled from thin air; they receive a demonstration. That level of transparency was technically impossible to produce at scale and within the timescales an active market expects, without algorithmic assistance.
Speed, for its part, changes something more discreet but decisive: between the moment a mandate is signed and the moment the property is visible to buyers, every day matters. A buyer visiting several properties each week, a market where listings move quickly — reducing that preparation window means keeping the attention of the right buyers at the right moment.
What the broker retains
An algorithm does not sit across the table from a seller who is hesitating between leaving now or waiting until the children have finished school. It does not notice that a buyer has asked the same question about the cellar three times, and that this is not curiosity but something holding them back. It does not negotiate. It does not read a sale deed to check that a pre-emption clause creates no problem. It does not know that a particular street in Pully feels different depending on whether one is looking for peace and quiet or proximity to the lake.
Property brokerage is a profession of judgement, exercised in situations where data is incomplete, where parties have opposing interests, and where a mistake can cost the person placing their trust in you several tens of thousands of francs. Affinités Immobilier never represents the seller and the buyer in the same transaction: the broker is on the side of whoever has mandated them, and them alone. No tool delegates that responsibility.
What AI produces is raw material. What the broker brings is judgement applied to that material — and moral ownership of the result.
Measuring the fit between property and buyer
One of the most concrete applications of this augmented approach concerns matching a property with potential buyers. Not every purchaser has the same constraints, the same timeframe or the same real financing capacity. Presenting a property to someone who cannot buy it, or who does not match the neighbourhood they are actually looking for, wastes everyone's time — and can sometimes cause genuine disappointment.
The Affinity Index is Affinités Immobilier's answer to that question: how to measure, out of one hundred points, how well a buyer fits a specific property. The chronicle The Affinity Index: matching the right home with the right person sets out the logic — eliminatory barriers first, then five weighted pillars. What matters here: this index is not a presentational gimmick. It structures the decision of who visits, and in what order.
For the buyer, the equivalent preparation step is the Buyer Passport: financing verified against supporting documents, dated, allowing the buyer to attend a viewing with demonstrated rather than assumed capacity. Both — the Affinity Index on the seller's side, the Passport on the buyer's — reduce noise in the sales process.
What "augmented agency" means
The term deserves to be spelt out, because it is easy to misuse. An augmented agency, as Affinités Immobilier understands it, is not an agency that has subscribed to a piece of software and placed an "AI" logo on its website. It is an agency that has identified the tasks where the machine delivers real value — volume of data, speed, reproducibility, transparency — and has built its own tools around those tasks, without transferring to the machine what must remain human.
In practice, for an owner considering selling, this translates into three visible differences:
- A documented valuation, comparable by comparable, rather than a price range announced verbally.
- A faster route to market, without sacrificing the quality of the file.
- A selection of potential buyers based on measured criteria, not an unqualified contact list.
For a buyer, the augmented agency also changes something: the properties presented to them correspond more closely to what they are looking for and can genuinely afford. Fewer pointless viewings, fewer disappointments, a more legible process. Purchasing capacity calculated in advance, the Buyer Passport assembled before the first viewing: these are steps that existed before AI, but which AI makes smoother and better documented.
What you can verify
The best way to find out whether an agency genuinely uses artificial intelligence in a useful way — rather than as a marketing argument — is to ask precise questions. The five questions to ask your broker before signing a mandate are a good starting point: they allow you to distinguish what is proven from what is merely claimed.
You can also ask to see a complete valuation, with its comparables. A serious valuation does not fit on a single line. It shows the transactions selected, explains why others were excluded, and documents the gap between the property being assessed and each of them. If the agency cannot show you that, the technology it lays claim to has not yet reached the result.
Artificial intelligence makes a broker's work faster and more demonstrable; it does not replace them where trust, judgement and responsibility are at stake.
If you are considering buying or selling in French-speaking Switzerland — whether in Lausanne, along the Riviera, or in a commune of Lavaux — the question of which agency to choose deserves to be asked with precision. What you are looking for is not an agency that has adopted a fashionable word, but one whose tools are visible in the result: the quality of the valuation, the rigour of the selection, the clarity of the process. Alexandre can show you how it works, applied to your specific situation, with no commitment required.
