DATACENTER SOFTWARE PROJECT

RootpassChange-impact tool for data center constructionReact + Vite demo / graph traversal engine / demo.getrootpass.com
  • Rootpass is a tool for data center construction teams to understand what a design change will break before it reaches coordination, fabrication, or the field.
  • The demo loads a synthetic DH-North project, then traces from changed equipment such as CDU-01 through connected spools and downstream dependency edges.
  • The traversal engine walks the graph to classify direct and indirect hits, then rolls those nodes into cost exposure, labor hours, schedule slip, and a re-issue package.
  • AI Assist parses bulletin text with a local LLM path and a keyword fallback, extracting equipment IDs, spool IDs, zones, and change type before the graph engine runs.
  • We applied to YC for the Fall 26 batch and are still pursuing Rootpass on the side.
