Advent Co-Leads $1.5 Billion Investment In Shield AI

Shield AI secured $1.5 billion to acquire Aechelon's simulation tech supporting Pentagon training and accelerate AI autonomy across military aircraft, with 140% valuation growth in one year.

  • On Tuesday, Shield AI announced $1.5 billion in Series G funding, pushing the autonomous military aircraft maker's post-money valuation to $12.7 billion.
  • Shield, founded in 2015 by brothers Brandon Tseng and Ryan Tseng and Andrew Reiter, has seen its valuation grow nearly fivefold in roughly two and a half years from $5.3 billion in March 2025.
  • Proceeds will support the acquisition of Aechelon Technology, which builds simulation environments for the Pentagon's Joint Simulation Environment, enabling Shield to integrate synthetic training data into its "Hivemind Foundation Model for Defence."
  • Led by Advent International, the round includes $500 million in preferred equity from Blackstone; Advent's chairman David Mussafer will join Shield's board while JPMorgan Chase's Todd Combs serves as board observer.
  • This investment arrives amid record capital flows into defense technology, which reached $49.1 billion in 2025, driven by geopolitical tensions in the Pacific and the war in Ukraine.
