Valley of Death

In The Kill Chain, Christian Brose uses “valley of death” as the named term for where defense-technology startups go to die: opportunities to help the military “increasingly amounted to little science projects and technology demos that often failed to transition into large military programs but disappeared instead into what became known as the ‘valley of death.’” The consequence is structural attrition — these companies “found it increasingly difficult to sustain themselves, attract private investment, and grow,” so “more and more of them were driven out, dropped out, or stayed out altogether.” Kyle’s margin note simply flags the passage: “Valley of death.”

The concept connects to the venture-capital framing in The Power Law, which the The Kill Chain page cites for the bleaker investor read — “defense is no place to start a company unless you’re already a billionaire” — pointing at how defense capital is structured to leave the demo-to-program gap unfunded.

Context: “Valley of death” is a widely used term in technology commercialization and defense acquisition for the funding/maturity gap between a successful prototype or research result and a fielded, scaled product — the stage where many otherwise-promising ventures fail to secure the capital or program-of-record support needed to cross over.

Where this appears

• The Kill Chain — Brose’s named term for the gap where defense-tech demos fail to transition into programs, starving startups of investment; Kyle annotates the passage directly, with The Power Law supplying the parallel VC framing
