Shield AI was founded in 2015 by brothers Ryan and Brandon Tseng with Andrew Reiter. The company builds AI pilots and drones for defense.
Ryan Tseng served as CEO. In April 2024 a V-BAT drone injured a US Navy service member while he was CEO, and he later said he felt terrible about it.
On 12 March 2025 Gary Steele replaced him as CEO. Tseng became Chief Strategic Officer.
The Tseng brothers were named to the WIRED25 list in 2020.
