a16z, Sequoia, and others are increasingly investing in defense tech startups; PitchBook: US VCs invested $33B in the sector in 2022, up from below $16B in 2019

Context & Ripple Effects
The $33B figure was the first hard marker of a category shift: US VC funding for defense tech more than doubled from below $16B in 2019 to $33B in 2022, with a16z and Sequoia crossing a line Silicon Valley had long avoided. The move was never just checks — a16z built the largest lobbying operation among VCs, spending almost $1M in 2023 to clear the Washington path for its defense portfolio.
What began as a US story quickly globalized: European defense startups, which raised just €30M in 2020, drew €2.4B since 2022, and by 2024 US VCs supplied 65% of the VC money into European defense, up from 18% a year earlier — the same firms exporting the thesis abroad.
First-order effects
- Defense tech startups gain access to venture-scale capital for the first time, while a16z, Sequoia, and their peers take on government customers whose procurement cycles, not consumer growth curves, become the return driver.
Second-order effects
- Capital chases policy: a16z's nearly $1M in 2023 lobbying spend — the most of any VC — shows defense investing forcing firms to buy influence in Washington that consumer portfolios never required.
- The thesis exports: US VC money flowing into European defense startups at 3x+ any prior year in 2024 pulls European founders into a funding market previously closed to battlefield tech.
Third-order effects
- If the pattern holds, defense becomes a standing VC allocation rather than a taboo — Bain counts sector deal value up 18x in a decade and the industry is positioned for an AI, drone, and space deal surge, with venture-backed startups competing alongside traditional primes for government contracts.
- The talent side follows the capital: tech workers' embrace of battlefield tech, documented as VC defense funding hit $108B across 2021–2023, erodes the cultural barrier that once kept engineers out of the sector.
The trend: Venture capital is re-militarizing — defense tech is moving from taboo to a standing allocation in top-tier funds, with lobbying and cross-border capital following the money.
