Rebellion Defense, a developer of AI solutions for U.S. defense, tells Axios that it has raised $150 million in venture capital at a $1 billion pre-money valuation. Why it matters: Defense is becoming more about code than combat, and Rebellion is part of a new generation of startups working to keep the U.S. and its allies ahead of their adversaries. “There is a new wave of people coming into VC who have the courage and tenacity to support our nation’s defense,” says Rebellion CEO Chris Lynch, who formed and led the Pentagon’s Digital Defense Service under Presidents Obama and Trump. Lynch, who calls his former DOD team a “SWAT team of nerds,” adds that Rebellion currently has around 160 employees and plans to add several hundred more — most of whom will be software engineers. Insight Partners and existing investor Venrock co-led the round, and were joined by Innovation Endeavors, Declaration Partners and Lupa Systems.
