Andreessen Horowitz

Andreessen Horowitz appears in Parker Conrad on Zenefits, Rippling, and Building Through Crisis through Parker Conrad’s account of the Zenefits aftermath. Conrad says Sam Altman warned Mark Andreessen that continued attacks on Conrad risked the firm’s relationship with Y Combinator, after which Andreessen spoke with David Sacks and the orchestrated attacks stopped.
