POLL: From FAANG to Founder

Amongst the FAANG companies which has the most number of individuals whom pivoted their career and found their own Startup (successful or moderately successful). Can be individuals you personally know, or just someone you generally are aware in the industry. If multiple, select the highest, or last FAANG they worked for before founding their startup I realise this poll could be skewed for many reasons. E.g, the number of founders that have no or little prior big tech experience are much likely to have found their Startups.
