Launch HN: Rudus (YC P26) – AI for concrete contractors

Rudus, an AI-powered takeoff and estimation platform for concrete subcontractors, automates manual workflows by identifying concrete structures and generating detailed line items. Founders Rishi and Sahil highlight the industry's outdated 20-year estimation process, where estimators manually trace PDFs and build spreadsheets, causing delays and limiting bid capacity. Rudus integrates into existing workflows using computer vision to process structural PDFs, expanding assemblies into priced line items while allowing estimator overrides.
