A Detroit startup just raised $11.5m from some big names.

Nox Metals, a seven-month-old Southwest Detroit company, has closed an $11.5 million seed funding round backed by prominent investors including Y Combinator, Hyperion, and Palmer Luckey. The company specializes in custom aluminum blocks for CNC machining and uses AI automation to dramatically speed up production—cutting lead times from days down to seconds. The funding will support product development, market research, and hiring as the startup scales.
