Business context


In the Netherlands and Germany, the real estate market faces a significant challenge with the imbalance between the high demand for rental properties and their scarce availability. Renters often encounter lengthy queues and rapid turnovers in property listings, which makes securing a rental highly competitive. 

Therefore, Genuisee’s goal was to create a platform to expedite the search process, offering users real-time updates on new rental properties. This enables potential renters to be among the first to know about new listings, significantly improving their chances of securing a property in a fast-paced market.

Challenges


Data collection was slow

RentSlam needed to enhance the speed of its data collection to outpace competitors and provide users with timely information.

Website dynamics

Frequent updates and changes on real estate websites required continuous adjustments in data scraping techniques, making it challenging to maintain accuracy and reliability.

Poor UX/UI

The clients web application suffered from suboptimal UX/UI design, resulting in a lacklustre user experience and diminishing the overall perception of their product and service.

Solutions we implemented

As strategic technology partners, we focused on overhauling the data scraping capabilities to ensure RentSlam could deliver real-time, accurate rental listings faster than ever.


  1. Broader platform coverage. We expanded the list of real-estate websites the system can parse, giving users a wider and more reliable search landscape.
  2. Smarter automation. We rolled out new internal tools that cut down manual scraping workflows and accelerate data processing end-to-end.
  3. LLM-driven extraction. By embedding advanced large language models, we improved how the platform interprets messy or inconsistent website structures, resulting in cleaner, more relevant data.
  4. Stronger stability. We upgraded error-handling logic and tightened the onboarding flow for new client integrations to ensure smoother platform adoption.
  5. Faster page delivery. Using reusable design-system components, we shipped new web pages quickly and supported the transition from the legacy app without disruption.
