This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
QuinStreet operates a performance marketing business that generates leads for clients in sectors including education, financial services, and insurance. This model relies on tracking and analyzing user behavior across digital channels to target and deliver potential customers. The company’s technology infrastructure, which captures and processes detailed user data for client acquisition, functions as a commercial surveillance system.
While QuinStreet’s systems are built for marketing, the underlying data harvesting and profiling capabilities are substantively similar to intelligence-gathering platforms. A 2017 Foreign Intelligence Surveillance Court opinion revealed that an unnamed internet company, later identified through reporting as likely being QuinStreet, challenged a National Security Letter (NSL) in 2014. This indicates the company possessed user data of a type and scale that attracted government surveillance demands under the USA PATRIOT Act.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
This information is provided for educational and transparency purposes only and should not be relied upon as investment advice. Data is drawn from independent watchdogs, NGOs, government registries, and Ethical Capital's ongoing research — see Research Sources for the full list.
