Marc Andreessen — Birth Year: 1971

NoteThe source directly confirms Marc Andreessen's birth year as 1971. The Wikidata entry lists his date of birth as '9 July 1971' with a reference to Encyclopædia Britannica Online. There is a minor discrepancy in the day/month (9 July vs 9 September according to Library of Congress Authorities), but both sources agree on the year 1971. The claim only specifies the birth year, not the specific date, so this is confirmed.
