# Andreessen Horowitz Silicon Valley's most powerful venture capital firm and — alongside [[Founders Fund]] — one of two VC firms defining the defense tech asset class. Founded in 2009 by [[Marc Andreessen]] and [[Ben Horowitz]]. Manages $45B+ in assets across AI, crypto, bio, games, infrastructure, and its defense-focused [[American Dynamism]] practice. The firm that raised $15B in January 2026 — its largest haul ever — with $1.176B dedicated to American Dynamism. ## American Dynamism Practice Launched January 2022 by [[Katherine Boyle]] and David Ulevitch. Invests in defense, aerospace, public safety, manufacturing, energy, logistics, and critical infrastructure. The thesis: "a technologically strong America is a force for good in a dangerous world." ### Fund Growth | Year | Commitment | Context | |------|-----------|---------| | Jan 2022 | Launch | Practice announced, no dedicated fund yet | | May 2023 | $500M | First dedicated American Dynamism fund | | Apr 2024 | $600M | Expanded commitment, Erin Price-Wright joins for energy | | Jan 2026 | $1.176B | Part of $15B mega-raise — a16z's largest fund ever | Total American Dynamism capital: ~$2.3B+ committed since inception.

This includes portfolio companies AND non-portfolio companies they want to signal-boost. Companies like [[Hadrian]], [[Hermeus]], [[Epirus]], and [[Saildrone]] appear on the AD50 list but are not necessarily a16z investments — they may be backed by [[Founders Fund]], [[8VC]], Lux Capital, or others. ## Crypto Fund a16z operates one of the world's largest crypto funds: - **$4.5B dedicated crypto fund** — among the largest in the sector - Planning a **fifth crypto fund targeting $2B** (announced early 2026) - Top-three funder of [[Crypto Super PACs]] alongside Coinbase and Ripple - [[Marc Andreessen]] personally donated $33.5M to pro-crypto political groups The crypto and defense portfolios create a dual-influence model: a16z funds both the weapons and the financial infrastructure, while its founder recruits the people who regulate both. See: [[Crypto-Political Machine]]. ## Political Activities ### Lobbying - **$1.49M** in federal lobbying spending (2025) — more than the National Venture Capital Association - $1.8M in all of 2024; $950K in 2023 — trend is sharply upward - First added the **National Defense Authorization Act** to its lobbying agenda in late 2023 - Filings show growing efforts to frame tech and finance through a national security lens - Launched the **Dynamic Tech Defense Reform Initiative** to influence NDAA procurement reforms - Backed **Leading the Future**, a pro-AI network of PACs ### Trump Administration Access - [[Marc Andreessen]] endorsed Trump (July 2024) alongside Ben Horowitz - Andreessen donated $3M to [[MAGA Inc.]] super PAC - Became an "unpaid intern" at [[DOGE Ecosystem]], vetting candidates for the Trump administration - Washington Post described Andreessen as "a key networker for talent recruitment" - Logged "significant hours at [[Mar-a-Lago]]" shaping tech, business, and economics policy - In-house policy team is described as "bipartisan," with government affairs leaders recruited from both sides ### Defense Reform Advocacy a16z has published extensively on defense procurement reform through its website, including: - "To Secure America's Future, We Must Fix Defense Procurement Now" - "Why America Needs Dynamic Defense Reform" - "How the U.S. Can Rewire the Pentagon for a New Era" - "Investing Capital to Defend the Nation" These publications frame startup-friendly procurement as a national security imperative — which conveniently benefits a16z's portfolio companies that compete with legacy defense primes for Pentagon contracts. ## The Co-Investment Network a16z's defense portfolio overlaps heavily with other politically-connected VC firms: | Company | a16z | [[Founders Fund]] | [[8VC]] | General Catalyst | Other Notable | |---------|------|---------------|-----|-----------------|---------------| | [[Anduril]] | ✓ | ✓ (led $1B Series G) | ✓ | ✓ | [[In-Q-Tel]], Valor Equity | | [[Shield AI]] | ✓ | | | | L3Harris, Hanwha | | [[Saronic Technologies]] | ✓ (led B) | | ✓ | ✓ | Elad Gil | | [[Castelion]] | ✓ | | | ✓ | Altimeter, Lightspeed | | [[Flock Safety]] | ✓ (led) | ✓ | | | Greenoaks, Kleiner Perkins | | [[Applied Intuition]] | ✓ | | | ✓ | Lux, BlackRock | | [[Hadrian]] | AD50 | ✓ (led $260M C) | | | Lux Capital | | [[Hermeus]] | AD50 | ✓ | | | In-Q-Tel, [[Sam Altman]] | | Epirus | AD50 | | ✓ (led $250M D) | | [[General Dynamics]] | **[[Founders Fund]] co-invests in 17 companies alongside [[8VC]].** The co-investment web between a16z, [[Founders Fund]], [[8VC]], General Catalyst, and Lux Capital creates an interlocking funding network where the same handful of firms control access to capital for the entire defense tech sector. ## Conflicts and Controversies ### The Influence Loop 1. a16z invests in defense companies (American Dynamism) 2. a16z lobbies for procurement reform (NDAA, defense reform initiative) 3. a16z's founder recruits government personnel (DOGE) 4. a16z hires former regulators (Anne Neuberger) 5. Portfolio companies win contracts from the government a16z helped staff This is the same self-reinforcing loop documented in [[Defense Tech Conflicts of Interest]] for the [[Peter Thiel]] network — but a16z operates it from a different political lane (centrist-techno-optimist rather than libertarian-authoritarian). ### Flock Safety Civil Liberties Concerns a16z's biggest American Dynamism bet by valuation ($7.5B) is [[Flock Safety]], whose automated license plate reader (ALPR) network has drawn sharp criticism: - EFF documented police using Flock to **surveil protesters and activists** - ACLU documented searches targeting **Romani people**, **women seeking reproductive healthcare**, and **immigrants** - Flock data shared with ICE for immigration enforcement under Trump administration - Austin and Denver rejected/dropped Flock contracts over civil liberties concerns - 6,000+ municipalities in 42 states use Flock — billions of plate scans per month ### Techno-Optimism as Cover [[Marc Andreessen]]'s "[[Techno-Optimist Manifesto]]" (Oct 2023) frames democratic oversight of technology as an "enemy" while a16z's American Dynamism practice depends entirely on centralized government procurement. The ideology celebrates anarcho-capitalism; the portfolio requires Pentagon contracts. ## See Also - [[Marc Andreessen]] - [[Katherine Boyle]] - [[American Dynamism]] - [[Founders Fund]] - [[Anduril]] - [[Shield AI]] - [[Saronic Technologies]] - [[Flock Safety]] - [[Castelion]] - [[Applied Intuition]] - [[Defense Tech Conflicts of Interest]] - [[Revolving Door]] - [[Crypto-Political Machine]] - [[Defense Tech as Asset Class]] - [[Military-Industrial Complex 2.0]]
