The biggest names in attendance were Apple's Tim Cook – who publicly supported Trump's Democratic rival Hillary Clinton – and Tesla founder Elon Musk, who would meet Trump separately after the roundtable. 

Looking around the room Trump called the group gathered 'amazing' and then boasted about the stock market 'bounce' that followed his election, which helped many of the businesses represented in the room.   

'So right now everybody in this room has to like me – at least a little bit,' Trump told the crowd. 

'But we're going to try and have that bounce continue,' Trump pledged. 

It was Peter Thiel, Trump's one prominent Silicon Valley backer, that brought the tech titans and the president-elect face-to-face. 

Safra Catz, the CEO of Oracle, had been the first to arrive at Trump Tower, after issuing a statement setting out what she, and likely the others, were likely to say. 

'If he can reform the tax code, reduce regulation, and negotiate better trade deals, the U.S. technology community will be stronger and more competitive than ever,' Catz said in a statement.
