Google DeepMind — Founded Date: Sep 2010

Note: The claim states the founded date as 2010-09 (September 2010). The source explicitly states incorporation on 23 September 2010, which matches the month and year claimed. The date precision difference (month-level vs. day-level) is not a contradiction per the guidelines. The additional context about the three founders is also confirmed by the source.

Note: The source confirms the founding date was in September 2010 (2010-09), matching the claim's year and month. However, the source provides a specific date of 23 September 2010 rather than just the month. The source also distinguishes between incorporation (23 September 2010) and official launch (15 November 2010). The claim's format of '2010-09' is less precise than the source's '2010-09-23', but the month and year are confirmed. The additional context provided in the claim (founders' names and London location) is also confirmed by the source.
