TLDR: Europe’s top court last week struck down Privacy Shield, a data transfer pact between the European Union and the United States that allowed U.S. companies to process and store European users’ data in America. The decision, which could have an outsized impact on U.S. startups, stems from U.S. government surveillance programs that European courts have repeatedly found issues with—especially in the wake of the disclosures from former National Security Agency contractor Edward Snowden in 2013. Without the U.S. scaling back its sweeping surveillance programs, however, it’s unlikely that the EU and U.S. will be able to agree on a new framework to replace Privacy Shield—something that growing startups need to reach potential users across Europe.
