Mach Industries Raises $100M Series B to Scale Advanced Defense Manufacturing and Autonomous Systems
Mach Industries, a fast-growing defense technology company specializing in advanced unmanned systems and integrated manufacturing solutions, has secured significant new capital as it scales operations and expands its technological footprint. In June 2025, the Huntington Beach, California-based startup closed a $100 million Series B funding round, marking a major milestone in its rapid growth trajectory since its founding in 2023.
The latest financing was co-led by venture capital firms Khosla Ventures and Bedrock Capital, both of which played a central role in attracting other institutional investors and deepening confidence in Mach’s long-term vision. Participation in the round also included existing backers such as Sequoia Capital, underscoring continued support from major Silicon Valley investors with a track record of backing disruptive technology companies.
Mach’s Series B brings the company’s total funding to roughly $185 million raised across multiple rounds since launch, reflecting increasing investor appetite for dual-use technology enterprises that operate at the intersection of commercial innovation and national security. The start-up had previously closed a $5.7 million seed round in June 2023 led by Sequoia Capital — the firm’s first ever investment in a hardware defense startup — followed by a $79 million Series A led by Bedrock Capital in October 2023, which valued Mach at approximately $335 million at that time.
The new funding round has elevated Mach’s valuation to an estimated $470 million post-money, illustrating the company’s rapid ascent and the strength of investor conviction in its strategy. Leadership at Mach has emphasized that the fresh capital will be used to further industrialize its core manufacturing and deployment capabilities, including scaling its flagship factory, Forge Huntington, and advancing tactical engine production through a division called Mach Propulsion.
Mach’s technology portfolio includes unmanned systems such as Viper, Glide, and Stratos, designed for a range of defense missions. Its manufacturing platform, Forge, aims to give the company a vertically integrated industrial base that can produce advanced systems with greater speed, resilience, and adaptability compared with traditional defense contractors.
Founder and CEO Ethan Thornton, who launched the company at age 19 after departing MIT, commented that the Series B investment positions Mach to accelerate its mission of enhancing U.S. military readiness and preserving strategic advantage. Investors also highlighted Mach’s model as a novel approach in defense tech, blending Silicon Valley-style innovation with hard defense engineering to meet shifting defense needs.
In addition to the defense-focused capital raise, Mach has also seen momentum in broader applications of autonomy technology. In late 2025, the company closed a separate $7 million funding round aimed at accelerating autonomous solutions for off-road equipment across agriculture, defense, and landcare industries. This round was led by The Venture Collective (TVC) and included participation from Next Level Ventures and Midwest Growth Partners, reflecting investor belief in the commercial potential of Mach’s autonomy stack beyond purely defense uses.
The $7 million financing is tied closely to Mach’s efforts to scale production and support a growing ecosystem of over 25 OEM partners integrating its hardware and software platform into next-generation machinery. As autonomous systems become increasingly integral to industrial and defense supply chains, these partnerships aim to broaden Mach’s impact and revenue streams.
Mach’s autonomy technology has accumulated significant real-world validation, with more than 500,000 driverless miles and 250,000 operational hours in the field, a performance benchmark that investors and partners cite as key evidence of the platform’s robustness and commercial readiness.
Taken together, Mach’s funding successes reflect a broader trend of private capital flowing into companies that fuse advanced manufacturing, autonomy, and defense technology. For Mach, the new capital not only provides the financial runway for accelerated growth but also signals confidence in its ability to deliver complex systems that meet both market demand and national security priorities.
