Mach Industries has raised $300 million in a Series C funding round, pushing the company's valuation to $1.8 billion.
Infinite Capital led the round, which included participation from existing investors such as Sequoia Capital, Bedrock Capital and Khosla Ventures.
The most recent funding brings the valuation of Mach Industries to nearly four times its valuation of around $470 million in June 2025 when the company raised $100 million.
Founded in 2023 by Ethan Thornton, the company develops autonomous military systems and aircraft programs for defense customers.
Defense Capital Flows Continue
The increased valuation of the Mach Industries is coming on the heels of defense-related tech firms seeing steady investment.
It's been a few years since investors have been attracted to companies that are working on autonomous systems, missile technology and defense manufacturing capabilities, as well as drones. This trend has occurred despite increased military spending and demand for arms in the major economies.
The total amount of global military spending in 2025 was $2.89 trillion, representing a 9.4% increase from 2024, according to the Stockholm International Peace Research Institute (SIPRI) report Trends in World Military Expenditure 2025. The United States was the biggest spender of military force followed by China, Russia, Germany and India.
The report pointed out that military spending has increased for the past 11 years, while Europe, Asia and North America have been seeing overall growth in defense spending.
Manufacturing Becomes a Key Focus
Mach Industries has matched the development of its products with the expansion of its manufacturing.
It currently has approximately 350 employees and a 115,000 square foot manufacturing plant in Huntington Beach, California. It aims to expand production capacity to 4 more plants by the end of 2026.
The company has five programs under development – Viper, Glide, Stratos, Dart and Pike – and is planning to put at least three into production next year.
Mach Industries stocked the rocket motor manufacturer Exquadrum earlier this year at a price of $50 million, either in cash or equity. The buy comes as defense contractors have said they are facing delays in getting the propulsion system components they need for rockets.
In addition to the list of government-backed programs, Mach Industries recently won a contract with the Defense Innovation Unit (DIU) under the U.S. Navy's runway independent strike aircraft initiative.
The latest investment round brings Mach Industries into the ranks of a growing alphabet soup of private defense tech startups that are gaining momentum as governments invest in growing autonomous systems and defense manufacturing capacity.
