Adam raises $4.1 million for AI copilot in 3D CAD

Investors are betting on a new way to automate professional 3D design as Adam closes a $4.1 million seed round led by TQ Ventures to build an AI copilot for CAD. The startup drew wide notice during Y Combinator’s Winter 2025 batch and now seeks to translate that momentum into enterprise-grade tooling.

Adam’s system is being designed to let engineers manipulate 3D objects by selecting parts, issuing natural-language instructions, and conversing with the model inside their existing tools, with an initial integration targeting Onshape, a cloud-based CAD program. By meeting users inside established workflows, the AI copilot is framed as a direct productivity lift for mechanical design teams.

The company first captured attention with a text-to-3D app that turned prompts into 3D models for creators, a capability that provided a springboard into more rigorous CAD use cases. That early traction now feeds a pivot toward enterprise deployment by year end, where the AI copilot will focus on simplifying and accelerating mechanical engineering tasks.

The round includes support from angel investors linked to Posthog and YC, alongside endorsements from industry figures such as Vercel’s founder, signaling rising confidence in specialized design automation. With capital and validation in place, the AI copilot strategy positions Adam to compete on usability inside high-stakes engineering workflows rather than on standalone novelty.

Across the software market, companies are racing to embed generative assistants into domain tools as cloud-based stacks normalize digital modeling, and CAD is a natural venue for that race. For global investors looking for durable adoption, an AI copilot embedded in Onshape-like environments represents a bet on sustained enterprise demand for faster iteration, and it hints that engineering content will be authored as much by conversation as by clicks.
