C-Infinity

C-Infinity is a Mountain View, California company founded in 2023 that builds foundational AI for mechanical design and manufacturing — AI that reasons about geometry, motion, spatial constraints, and production logic. Its platform, AutoAssembler, connects directly to existing CAD and PLM environments to automate assembly process planning, accelerate engineering change order (ECO) reviews, and generate production-ready assembly work instructions, compressing work that historically took weeks into minutes. The product is described by the company as API-first, with an integration layer that connects upstream to engineering systems and downstream to production, but as of July 2026 C-Infinity publishes no public developer portal, API reference, SDKs, or OpenAPI definition — the AutoAssembler application is gated behind a request-a-demo flow and integration is arranged directly with the company. C-Infinity raised a $16M round in April 2026 led by Canaan Partners, with participation from Inventus Capital, Bee Partners, and Radius Capital, and reports deployments across Global Fortune 100 manufacturers as well as small and mid-sized enterprises.

C-Infinity is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Manufacturing, CAD, and PLM.

C-Infinity’s developer surface includes signup flow, engineering blog, YouTube channel, and 8 more developer resources.
