“I joined the board there in 2007 so I've seen everything in the last almost 20 years every step of the way.”
Marc Andreessen, interviewee 26 January 2025 Transcript for Marc Andreessen: Trump, Power, Tech, AI, Immigration & Future of America (Lex Fridman)
Marc Andreessen joined the Facebook board in 2007.
Mostly true True in substance, wrong in a detail.
What would count as true or false
The test is the year Marc Andreessen became a director of Facebook (now Meta). True: official records show he joined the board in 2007. Mostly true: he joined in 2006 or 2008. That is a one-year slip, and the claim's main point, that he has served for most of the company's history, still holds. Mostly false: he joined the board, but two or more years away from 2007. False: the records show he was never a Facebook director.
Evidence
- Marc Andreessen Joins Facebook Board of Directors Facebook, Inc. (about.fb.com newsroom) · 30 June 2008
“PALO ALTO, Calif. — June 30, 2008 — Facebook today announced that Marc Andreessen has joined its board of directors.”
- Marc Andreessen Officially Joins Facebook Board of Directors Adweek · 30 June 2008
“Facebook announced today that Silicon Valley luminary and current Ning Chairman Marc Andreessen has officially taken the fourth seat on Facebook’s board.”
- Facebook | The Info Web The Info Web
“Andreessen is listed as a director since June 2008 and as a general partner of Andreessen Horowitz since July 2009.”
Reasoning
Facebook's announcement dated June 30, 2008 says Marc Andreessen joined its board of directors that day (E1). Adweek reported the same appointment on the same date (E2), and a third source lists him as a director since June 2008 (E3). He joined in 2008, not 2007. Under the criteria, a one-year slip counts as mostly true.
