Logan Green and Carl Icahn
In May 2015, Carl Icahn, one of Wall Street’s most feared activist investors, put $100 million into Lyft, the ride-hailing startup Logan Green had co-founded three years earlier.

A decade later, Green stepped off Lyft’s board after a two-year handover and became a venture partner at Autotech Ventures. Icahn, meanwhile, kept running his holding company, Icahn Enterprises, into his 90th year, naming a new CEO in May 2026.
