Andreessen Horowitz backs Flock surveillance network while funding crypto privacy projects

Andreessen Horowitz (a16z) is simultaneously supporting two seemingly opposite agendas: a surveillance network that tracks vehicle license plates across the United States and a portfolio of crypto‑related startups that aim to protect financial privacy.

Flock investment and controversy

a16z has been an investor in Flock since 2021, participating in multiple funding rounds that have helped the company raise over $1.2 billion and achieve an $8.3 billion valuation. Flock’s automated license‑plate readers (ALPRs) are deployed in more than 120,000 cameras across 49 states, covering roughly 7,000 cities. The company claims its technology reduces crime, but it faces growing backlash. As of August 28 2026, at least 220 contracts with law‑enforcement agencies had been terminated, and protests have led to cameras being removed in several locations.

a16z’s crypto‑privacy investments

In a separate effort, a16z’s crypto team has funded a range of projects focused on protecting online and financial privacy. Notable investments include:

• Nym Technologies – a virtual private network that hides metadata on internet traffic.
• XMTP – an encrypted messaging protocol.
• Aleo – a platform for private smart contracts on blockchains.
• Aztec – a protocol enabling private transactions on Ethereum.
• Zcash Open Development Lab – a team advancing Zcash, a privacy‑focused cryptocurrency.

The crypto team has publicly called for an end to “the era of mass financial surveillance” and has criticized government actions that restrict privacy‑enhancing DeFi tools.

Public statements and legal context

a16z partners David Ulevitch and Alex Immerman have defended Flock, describing it as a bridge to “objective policing” that protects communities. In contrast, a16z crypto has issued blog posts urging regulators to adopt blockchain‑based solutions and to avoid punitive measures against privacy‑preserving mixers such as Tornado Cash.

Potential implications

The dual strategy highlights a tension between public‑safety arguments for surveillance and the push for financial privacy. Ongoing legal battles over Flock’s use of ALPR data and regulatory debates on crypto privacy could affect both lines of investment.
