How a data engineer's side project became a market intelligence platform for real estate agencies across Luxembourg.
Real estate agencies in Luxembourg operate across multiple listing portals with no unified view of their market. Price changes happen silently. Competitors move without notice. And there's no simple way to see how your pricing compares to the commune median.
Agents end up relying on gut feeling and manual portal checks — time they could spend closing deals.
Palentier aggregates listing data from every major portal in Luxembourg, links it to your agency, and delivers a personalized feed: price drops in your communes, your positioning versus market medians, competitor activity, and inventory pressure — all in one place.
No spreadsheets. No manual tracking. Just the data your agency needs, scoped to the communes where you operate.
We track over 50,000 listings across all 102 communes in Luxembourg, with data refreshing daily. Every agency on the platform gets a market view built entirely from real listing data — nothing modeled, nothing estimated.
Palentier is built by a small team with deep experience in data engineering and a simple belief: agencies that see their market clearly will always outperform those that don't.
