Duct Stream is building drafting tools to power the future of the HVAC Industry.
 
For decades, the HVAC industry has been trapped in a "BIMnopoly"—locked into proprietary CAD formats that stifle innovation and hoard data. We are decoupling meaning from format to build the intelligence layer for the built environment. Our working API is already compatible with the industry's most popular estimation, fabrication, and drafting tools. We've already done the hard work of connecting the silos. We output clean, editable data generating de facto industry standards—PDFs and DWGs—instantly configured to individual shop standards. Our core technology and drafting workflows have been rigorously tested and validated by over 700 HVAC fabricators. Our proof-of-concept API is actively functioning and successfully generating manufacturable data that legacy platforms struggle to produce.
