CSET (Center for Security and Emerging Technology) — Founded Date: Jan 2019

NoteThe source is the official CSET About Us page and is the correct entity. However, the source text provided does not explicitly confirm the founding date of January 2019 or the $55M Open Philanthropy grant mentioned in the additional context. The only temporal clue is the reference to 'CSET at Five' in the 2023 annual report, which would place founding around 2018, not January 2019. The claim cannot be verified from the excerpt provided, though it is not contradicted either. The source may contain this information on other pages or in linked documents (like the annual report), but it is not present in the excerpt provided.
