The Brennan Center filed public records requests with police departments in Boston, New York City, Los Angeles, Baltimore, and Washington, D.C., seeking information about their use of third-party social media monitoring tools. The resulting documents revealed new information about how these tools are used and the relationships between law enforcement and these third-party vendors.
Below is information on what we know about each of the companies, including their data sources, the tools’ purported capabilities, and publicly available information about the companies’ public-sector clients, as well as relevant documents acquired through the Brennan Center’s public records requests. We will update this resource if we receive additional relevant documents.

Capabilities and data sources: Voyager Labs (Voyager) claims its tools use traceless collection methods for social media networks, which allow a user to:
Reconstruct closed profiles based on publicly available information.
Uncover the strength and nature of people’s connections on social media.
Identifypeople that are “most invested in a stance: emotionally, ideologically, and personally.”
Voyager claims that these insights are compiled by its proprietary AI technology, which doesn’t require the intervention of an analyst or investigator. Voyager also claims that its platform can instantly vet people on social media based on a user’s pre-determined set of questions.
Voyager positions itself as a social media search tool, as opposed to a tool that searches through the Internet in its entirety. Its sources include all major social media platforms, including Facebook, Twitter, Instagram, VK, TikTok, and Telegram.
Known clients: the LAPD conducted a four-month trial of Voyager’s tools between July and November 2019. There is one purchase order for Voyager products for the Council of the Inspector General on Integrity and Efficiency in 2021.
