A16z funds crypto privacy tools and Flock’s car-tracking

Andreessen Horowitz has increased investment in technology intended to improve privacy for cryptocurrency users and has backed Flock, a company that sells license-plate reader cameras and vehicle-tracking software. Flock markets its products to police departments, neighborhood groups and businesses. The company stores images and vehicle metadata and provides a searchable network to locate a car of interest.

On the crypto side, the firm has directed capital and engineering resources to teams developing zero-knowledge proofs, confidential transaction systems and open-source tools designed to make private transactions harder to link to individuals on public blockchains. Those efforts include funding research and developer tooling aimed at wider adoption of privacy-preserving methods.

The investments come amid regulatory scrutiny of both areas. Policymakers in the United States and abroad have examined privacy-enhancing services such as mixers and privacy coins for potential use in money laundering and sanctions evasion. Developers and investors are working on technical standards, compliance tools and proposals for clearer rules to allow privacy features while limiting illicit use.

At the same time, some city governments and privacy advocates have proposed restrictions or transparency requirements for automated license-plate reader networks, citing concerns about data retention, data sharing and long-term tracking. Law enforcement agencies and some customers say camera networks help solve property crime and monitor suspicious activity.

Andreessen Horowitz, founded by Marc Andreessen and Ben Horowitz, manages multiple funds including vehicles dedicated to crypto and broader technology investments. The firm’s portfolio includes infrastructure, applications and tools across digital and physical technology. Industry observers note venture firms often invest across sectors that raise different questions about privacy and public safety.
