Mach Industries, a leading defense manufacturer building advanced unmanned systems for modern defense, today announced it has raised $300 million in Series C funding. The new capital will accelerate execution of existing government contracts, talent acquisition, product development, and the expansion of Forge, the company's flexible manufacturing network.
The round was led by Infinite Capital and Ribbit Capital, valuing the company at $1.8 billion. The new investors join longstanding backers including Bedrock Capital, Sequoia Capital, and Khosla Ventures, an investor group that has supported Mach Industries across multiple stages of its growth.
Mach Industries exists to build next-generation defense systems that preserve an allied American technological edge. As drone warfare accelerates and adversaries field autonomous systems at scale, superiority will belong to those who can develop, manufacture, and deploy faster. Mach Industries is scaling to meet that moment.
"Today's Series C funding is a powerful accelerator for our mission," said Founder and CEO Ethan Thornton. "We're delivering advanced unmanned systems at the pace the threat environment demands, and we're grateful to our investors for believing in our ability to strengthen American and allied superiority on the battlefield."
