Mach Industries, a defense tech startup founded in 2023 by Ethan Thornton, has raised US$100 million in new funding, boosting its valuation to US$470 million.

The round was led by Keith Rabois of Khosla Ventures and Geoff Lewis of Bedrock Capital, with participation from Sequoia.

This brings the company’s total funding to US$185 million.

The previous series A round in October 2023 raised US$79 million at a US$335 million valuation.

The company has developed three weapons systems: a jet-powered UAV, a high-altitude glider, and an in-air satellite with sensors and communication tools.

It also secured contracts with the Army Applications Laboratory for a vertical takeoff precision cruise missile.

🧠 Food for thought

1️⃣ Defense tech venture funding is experiencing a historic surge

Mach’s $100 million round represents part of a significant larger trend in defense tech investing that’s gaining momentum.

Venture funding for defense tech startups reached a record $3 billion in 2024, marking an 11% increase from $2.7 billion in 2023 and surpassing the previous record of $2.6 billion set in 2022 1.

While the number of deals has fluctuated (increasing from 100 to 102 between 2023-2024 but down from 113 in 2022), the rising total funding indicates larger average deal sizes and more concentrated investments in promising companies 2.

This surge is driven by increasing geopolitical tensions and rising demand for innovation from defense customers and Congress, creating an environment where young companies like Mach can secure substantial funding despite modest valuation increases 3.

Mach’s funding is still dwarfed by industry leaders like Anduril, which raised $1.5 billion in 2024, and Helsing, valued at $5.4 billion, showing how the defense tech funding ecosystem is developing tiers of companies at different scales 2.

2️⃣ Youth-led innovation is reshaping traditional defense contracting

Mach Industries exemplifies a new generation of defense startups led by young entrepreneurs bringing fresh perspectives to an industry traditionally dominated by established contractors.

Founded by then 19-year-old Ethan Thornton who dropped out of MIT, Mach has grown from a scrappy startup where founders built their own furniture to a 140-employee operation with significant manufacturing capabilities in just two years 4.

Mach’s rapid progression from securing a $5.7 million seed round to a $79 million Series A, and now a $100 million Series B demonstrates how quickly promising defense tech startups can scale when addressing capabilities gaps with innovative approaches 4.

The company’s development of three weapons systems in this short timeframe highlights how these new entrants are accelerating innovation cycles compared to traditional defense procurement timelines 5.

3️⃣ AI-powered precision systems are redefining modern warfare requirements

Mach’s focus on developing “weapons for this new reality” aligns with a fundamental transformation in warfare driven by AI and autonomous systems.

The global military AI market is projected to reach $13.71 billion by 2030, reflecting the critical role AI is playing in reshaping military strategies through autonomous systems, predictive analytics, and advanced data processing 6.

Thornton specifically references Ukraine’s drone “Spider Web” attack on Russian bombers as an example of the AI-powered, pinpointed warfare that is already occurring, demonstrating how real-world conflicts are driving innovation requirements 4.

Defense investors are particularly interested in technologies including AI, autonomous systems, and advanced propulsion – precisely the areas where Mach is focusing with its vertical takeoff UAV (Viper), high-altitude glider (Glide), and in-air satellite (Stratos) 1.

The integration of AI in military operations represents a strategic overhaul in how nations leverage innovation for competitive advantages, with ethical considerations and regulatory frameworks still struggling to keep pace with technological developments 67.
