The third-generation owner of C&S Wholesale Grocers, Cohen joined in 1974, when it did $50 million in revenue; today it generates $25 billion. Looking to keep costs low, he began tinkering with automation in his warehouses. In 2007, he invested in a robotics automation rm that eventually developed a massive AI-powered warehouse robotics system. Now called Symbotic, it went public in a June SPAC deal and is automating all 42 of Walmart’s regional distribution centers. Cohen and his immediate family’s more than 70% stake makes up most of their wealth.
