Marc Andreessen — Birth Year: 1971

NoteThe source directly confirms Marc Andreessen's birth year as 1971. Multiple sections of the Wikipedia article state this consistently: the infobox shows '( 1971-07-09 ) July 9, 1971', the opening paragraph states 'born July 9, 1971', and the biographical section confirms 'Andreessen was born in Cedar Falls, Iowa'. The claim's additional context about the birth date (July 9, 1971 in Cedar Falls, Iowa) is also fully supported by the source.
