Shield AI, a San Diego-based defense startup, has announced a $1.5 billion Series G funding round that more than doubles its valuation to $12.7 billion. The company, founded in 2015, is projecting over 80% revenue growth this year, reaching at least $540 million. The funding will support the acquisition of tactical simulation firm Aechelon and the development of new combat drone technology.

Why it matters

The rapid growth of Shield AI underscores the increasing importance of modernizing military forces amid global conflicts. The company's AI-powered drone technology has seen strong demand, particularly with its deployment in active operations in Ukraine. This investment signals rising investor interest in defense tech startups as governments prioritize military modernization.

The details

Shield AI plans to use the new funding to scale its Hivemind autonomy platform and V-BAT surveillance drone, as well as develop a new combat drone set for its first flight by the end of 2026. The company is also acquiring tactical simulation firm Aechelon, whose platform will be integrated with Hivemind. Shield AI co-founder Brandon Tseng says the company operates 'in almost every single conflict zone', though he declined to confirm if its drones have been used in Iran.

What they’re saying

“We don't expect growth to slow down.”

“Countries around the world are modernizing their militaries, and obviously the U.S. has pushed for an increase in defense spend among all of its allies and partners. That certainly is in the background as investors think about investing in defense.”

— Brandon Tseng, Co-founder and President, Shield AI

What’s next

The final close of Shield AI's funding round will be contingent on approval of the Aechelon acquisition. If the deal fails to clear regulatory hurdles, the company will 're-evaluate' the financing with investors.
