Shield AI expands massive Series F with another $300M in equity, debt, scaling valuation to $2.8B

Defense tech startup Shield AI has expanded its latest funding round with another $300 million in equity and debt, bringing its total Series F to $500 million, TechCrunch has exclusively learned.

This total amount reflects $200 million in equity closed in November, $100 million in new equity raised at the Series F price and $200 million in debt. The debt provider is Hercules Capital; Shield declined to specify the source of the additional equity. The company’s valuation now stands at $2.8 billion, up from $2.7 billion in November.

Shield AI is building an “AI pilot” to turn aircraft into autonomous systems. Its flagship product, Hivemind, will let teams of aircraft operate independently of remote operators, communications or GPS. Shield CEO and co-founder Ryan Tseng credits the capability to recent advances in compute.

“AI pilots are becoming a strategic conventional deterrent in class with our aircraft carriers and guided missile submarines,” he said in a statement. “But interestingly, it’s the first strategic deterrent that is software-defined and has only recently become possible because of advances in AI and compute power. That’s a huge paradigm shift for aerospace and defense.”

While venture debt gets a bad wrap, it can make a lot of sense — especially for late-stage companies that need an injection of capital to reach the finish line (like profitability or exit). As opposed to being a last-ditch survival mechanism for struggling companies (as it sometimes can be for early-stage startups), venture debt at the later stage can be a smart way to capitalize a late-stage growth company.

The San Diego-based company recently launched V-BAT Teams, a software product that operates with Hivemind and enables teams of V-BAT drones to execute missions autonomously and in coordination.

In recent testimony before the U.S. Senate, president and co-founder Brandon Tseng stressed the importance of AI-piloted systems to the country’s overall deterrence strategy, saying, “We believe AI-piloted systems will be the greatest military deterrent of our generation. We must get it right.” However, he added that incorporating AI pilots into the DOD’s force structure had been “difficult and murky.”

“As we observe new types of warfare, where the large exceptional military arsenals we have built can be incapacitated by small, cheaply built adversary armaments, we need the DoD to change the way it builds its force of the future: switching the paradigm away from what worked in the past and focusing its resources on the next game-changing technological assets,” he said. “Adopt AI pilots too slow, and we will fail. Bold actions are required if we are to win.”
