STREETS vs W&W, compared honestly.
W&W Immo Informatik runs Swiss property management and accounting with ImmoTop2 and Rimo R5. STREETS is the data consolidation and reporting layer that sits above operational systems like these.
The short answer
W&W Immo Informatik has developed Swiss real estate software since 1981. ImmoTop2 and Rimo R5 are established, fully integrated property management and accounting systems, well suited to running the day-to-day management of rental properties and condominiums.
STREETS solves a different problem: pulling data across your operational systems, entities and property managers into one validated, portfolio-level view for oversight and reporting. Firms typically keep systems like ImmoTop2 or Rimo R5 and add STREETS as the control layer above them.
Where each one fits
W&W is a strong fit when
You need to run property management and accounting operations end to end on an established, integrated Swiss system.
STREETS is a strong fit when
Your data is spread across systems and property managers, and the priority is consolidation, validation and portfolio-level reporting rather than the operational workflow itself.
The distinction that matters
Operational systems manage processes well. What they are not designed to do is reconcile inconsistent data arriving from multiple systems and external property managers into one validated, portfolio-level source of truth, quickly and with a clear audit trail. That gap is usually filled with Excel.
STREETS replaces that manual layer with structured, validated, consolidated data and portfolio dashboards, working with whatever operational systems you already run. It is the control and reporting layer, not another operational system to migrate onto.
This reflects general positioning as of 2026. Confirm current specifics with each vendor for your own evaluation.
