Social Capital CEO Chamath Palihapitiya said Amazon CEO Jeff Bezos is a "fantastic" capital allocator and a maniacal CEO solely interested in running his company.
"They have a CEO that is unfortunately, you know, pretty lackluster. I saw him on 'Mad Money' and ... it was like human Ambien. I mean, it was pretty boring," he told CNBC's "Squawk Box."
"As a person that's worked for great leaders, and is around a lot of great technology leaders, it would be very difficult for me to work for him," said Palihapitiya, a Silicon Valley-based venture capitalist and former Facebook executive.
Social Capital has $1.2 billion in assets under management and focuses on early stage investments in education, health care, financial services, and enterprise and consumer segments.
Palihapitiya said he would work for Bezos in a heartbeat, and would have also worked for the late Steve Jobs.
