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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/rudus: open an issue to ask a question, or submit a pull request to add artifacts.
