NoteAll key fields in the record are confirmed by the source. The person (Demis Hassabis), organization (Google DeepMind/DeepMind), and role (CEO & Co-founder) are all explicitly stated. The startDate of 2010-09 (September 2010) is consistent with the source's statement that DeepMind was 'founded in London in 2010' and the institutional affiliation listing '2010–present'. While the source does not specify the exact month (September), the year 2010 is confirmed, and the month-level precision in the claim (2010-09) is not contradicted by the source's year-level statement.
