How a Gen Zer built a $3.7 billion defense tech startup backed by Sequoia

Preston Fore, reporting for Allie, introduces defense tech startup Mach Industries, which has just raised $600 million in a Series C extension, valuing the company at $3.7 billion. This significant increase marks a rapid growth trajectory for the 22-year-old founder and CEO, Ethan Thornton, who launched Mach in 2023. The startup, specializing in autonomous defense systems, has expanded its focus to include a variety of weapons programs and a large manufacturing facility in California.

Thornton, driven by concerns about China's rise during his teenage years, has built a company with a strong focus on rapid development and risk-taking. He emphasizes the importance of surrounding oneself with knowledgeable, challenging partners and encourages others to embrace failure as part of the journey to building a successful tech startup.
