Building PropTech in the Netherlands has historically been a fragmented experience. Developers have had to stitch together data from the BAG (Key Register of Addresses and Buildings), WOZ (Valuation of Immovable Property), Kadaster, and dozens of listing portals.
Today, we are changing that with the launch of Voseno.
The Problem
For years, accessing reliable Dutch property data meant:
- Maintaining fragile scrapers for listing sites
- Dealing with complex, outdated government XML feeds
- Spending months normalizing addresses and deduplicating records
The Voseno Solution
Voseno provides a single, developer-friendly API that aggregates:
- Real-time listings from 1,200+ sources
- Official register data (BAG, WOZ, Energy Labels)
- Neighbourhood context (CBS statistics, livability scores)
We handle the hard work of ingestion, normalization, and deduplication so you can focus on building your product.
