Rudus

Rudus is a Y Combinator (Spring 2026) startup building an AI-powered takeoff and estimation platform for concrete contractors and subcontractors. The software automatically detects and classifies concrete structures (footings, walls, columns, and slabs) from architectural plan sets, expands them into detailed assembly line items, and integrates into existing estimator workflows rather than replacing them. Rudus reports a 70-80% reduction in takeoff and estimation time, letting estimators submit more bids. Founded by Rishi Pankhaniya (ex-Airbnb) and Sahil Goel (ex-Amazon). As of this enrichment pass Rudus operates a lead-generation marketing site at rudus.ai with no public developer program, API, documentation, or self-service sign-up; this profile records that verified state.

Rudus is profiled on the APIs.io network. Tagged areas include Company, Construction Technology, Artificial Intelligence, Computer Vision, and Estimation.
