Stadswaarde

Amsterdam property intelligence: enter an address and get a complete investment analysis in 5 seconds. Built with Next.js and Supabase, powered by open data (BAG, CBS) and Altum AI.

Assessing a property as an investor meant hours of gathering data from separate sources. Stadswaarde flips that: enter an address and get a complete investment analysis in five seconds, with map data from open sources and paid sources like Altum AI. What used to be an afternoon of work is now a few seconds.
