-> Automated design tools for heat pump systems
-> A survey app for collecting property data on-site
-> 2D/3D floorplan creators (maybe even with LiDAR and CV!)
-> Country-wide data tools through large-scale scraping + mapping
-> Hardware integrations (e.g. bluetooth laser measures, sensors)
-> Offline-first/PWA apps for installers on the move
Tech Stack:
