The source text confirms that GiveWell was founded in 2007 and mentions it was founded by two individuals, but does not specifically name Holden Karnofsky or confirm his role as Co-founder & Co-Executive Director. The source also does not provide an end date (2014) for his tenure. While the source directs readers to 'our story' and 'meet our team' pages for more information, those pages are not included in the provided excerpt. Therefore, the specific claims about Holden Karnofsky's identity, his co-founder status, his co-executive director role, and his end date of 2014 cannot be verified from this source text alone.
