Rudus, a YC P26 company, launched on Hacker News in June 2026 with an AI that identifies concrete structures directly from construction plan sheets and eliminates hours of manual quantity takeoff. It is a vertical, document-vision application of AI aimed squarely at a non-software trade. It illustrates the continuing wave of narrow, domain-specific AI tools tackling tedious back-office estimation work.
