Personnel: Demis Hassabis at Google DeepMind (CEO & Co-founder)

NoteThe source directly confirms all key fields in the record: (1) person: Demis Hassabis ✓, (2) org: Google DeepMind ✓ (the source uses both 'DeepMind' and 'Google DeepMind' interchangeably, noting Google acquired it in 2014), (3) role: CEO & Co-founder ✓, (4) startDate: 2010 ✓ (the source states 'founded in London in 2010'). The record uses 2010-09 (September 2010) for the start date, and while the source does not specify the exact month, it confirms the year 2010 and founding status. This level of precision (month-level vs year-level) is acceptable and does not constitute a contradiction.
