Immowelt Data Parser & API

Immowelt is a leading German property portal — drawing an estimated ~12-13M monthly visits as the anchor of Germany’s #2 cluster — and PropAPIS extracts its resale, rental, and new-build listings through a single REST API. Owned by Aviv Group (KKR-majority) alongside Immonet, Immowelt is the main challenger to ImmoScout24, exposing price, living area, rooms, energy class, and agent data.

Platform Overview

Market Position

Immowelt is owned by Aviv Group (the Axel Springer real-estate vehicle, majority-owned by KKR), which acquired the Immowelt + Immonet cluster effective December 2024. Behind market leader ImmoScout24, Immowelt anchors the German #2 cluster, drawing an estimated ~12-13M monthly visits (SimilarWeb ).

• German #2 Cluster: Anchors the Aviv challenger group
• Aviv Group/KKR: Acquired Dec 2024 with Immonet
• ~12-13M Monthly Visits (est.): Broad German reach
• Aviv Group Family: PropAPIS covers the wider Aviv portal cluster

Aviv Group Portal Family

Immowelt’s owner, Aviv Group, operates a cluster of portals across Europe that PropAPIS covers as a connected family:

• Germany: Immowelt, Immonet
• France: SeLoger, Logic-Immo, Meilleurs Agents
• Belgium: Immoweb
• Austria: Immowelt.at, ImmoScout24.at

A single parser strategy can span much of this cluster thanks to shared technology and data pools.
