The Challenge

Bildsy aimed to bring multiple stakeholders—homeowners, contractors, and vendors—onto a single platform. Each user group had distinct goals, workflows, and decision-making needs, making clarity and role-based experiences critical. 

The challenge was to design a marketplace that simplified contractor discovery, bidding, and vendor search without overwhelming users or creating friction between roles. 

Key Pain Points 

  • Complex multi-user marketplace requirements 
  • Need for clear role-based workflows 
  • Inefficient contractor discovery and bidding processes 
  • Limited visibility into vendor options 
  • Risk of cognitive overload across screens
