Mach Industries raises $300M Series C at $1.8B valuation

Mach Industries has raised $300 million in Series C funding at a $1.8 billion valuation. The round was led by Infinite Capital and Ribbit Capital, with existing investors including Bedrock Capital, Sequoia Capital, and Khosla Ventures also backing the company.

The new capital is being used to accelerate execution of government contracts, expand hiring, develop products, and grow Forge, Mach’s flexible manufacturing network. Mach says it builds advanced unmanned systems for modern defense, and the funding underscores continued investor demand for companies building autonomous military hardware and production capacity.

The deal marks a sharp increase in valuation from the company’s prior funding round, which TechCrunch reported was $100 million in June 2025 at a $470 million valuation. TechCrunch said the company’s latest round lifts Mach to a $1.8 billion valuation, while reporting that it is a three-year-old startup founded by Ethan Thornton.
