Prototyping.io

Prototyping.io is a Y Combinator (Spring 2026) startup building AI-driven autonomous manufacturing for mechanical parts. The platform converts CAD designs into finished physical parts by automating design-for-manufacturability analysis, manufacturability evaluation, production planning, machine execution, and quality control across CNC machining, sheet metal, 3D printing, injection molding, extrusion, and die casting. Founded by Revanth Bodepudi (CEO) and Prerit Oberai (CTO) in the San Francisco Bay Area, it targets hardware teams in robotics, AI infrastructure, energy, automotive, and defense, aiming to cut hardware iteration cycles from weeks to days with no minimum order quantities and tight tolerances. The company is in early-access/waitlist stage and does not yet publish a public API, developer portal, SDK, or documentation surface.

Prototyping.io is profiled on the APIs.io network. Tagged areas include Company, Manufacturing, Hardware, CNC Machining, and 3D Printing.
