"This is a truly amazing group of people," he said. "There's nobody like you in the world. In the world. There's nobody like the people in this room. And anything we can do to help this go along, and we're going to be there for you."
But behind the cordiality was a sense of trepidation. Trump, both as candidate and president-elect, has used his perch to shame companies, and the consequences haven't been trivial.
When Trump tweeted earlier this month that he wanted to cancel Boeing's US$4b contract to build Air Force One, Boeing's stock price took a hit.
Trump has targeted Apple and other companies for manufacturing their products in China, and has called to raise tariffs on Chinese goods, a crucial issue for Silicon Valley companies that import widgets and other hardware components from China.
At the meeting, which included the leaders of Google, Microsoft, Intel, Oracle, IBM, Cisco, and Tesla, Trump seemed willing to back down from a signature campaign promise to end free trade deals.
"We're going to make fair trade deals," he told the executives. "We're going to make it a lot easier for you to trade across borders."
Last month, Trump negotiated with equipment maker Carrier, a division of United Technologies, to avoid losing 800 jobs to Mexico in exchange for US$7m in government subsidies. In the days leading up to the meeting, staff for the companies tried to parse whether the image-conscious Trump would try to use his leverage with them to do something similar.
After the CEO roundtable, Trump met privately with Tesla CEO Elon Musk and Apple CEO Tim Cook. Tesla manufactures its vehicles in California but purchases components from China. Apple hardware largely comes from China.
Attendees had a wide-ranging and generally positive conversation, discussing issues from visas for high-skilled immigrants to trade issues to the cloud, according to people familiar with the discussion.
Trump made cracking down on illegal immigration a central campaign promise, and called for an end to the high-skilled visa program during a presidential debate, though he later backtracked. Technology companies are some of the heaviest users of such visas.
At the meeting, Trump seemed open to keeping the high-skilled visa program, a person familiar with the discussion said.
The president-elect also heaped praise on Facebook board and transition team member Peter Thiel, shaking his hand and calling him a "special guy."
Trump made a point of saying that Thiel, who convened the meeting, nixed companies that were too small from attending. But one relatively small company with ties to Thiel made the cut: Palantir. Unlike the other companies in attendance, the data-mining start-up, which Thiel founded in 2004, is private and had revenue last year of less than $300m, according to a person familiar with the matter. A large portion of Palantir's business involves contracts with federal agencies, and the company is currently engaged in a lawsuit with the Department of Defense over the right to compete for more contracts.
The executives left as they arrived - wordlessly and quickly, striding through the lobby and ignoring press questions. Some smiled; Oracle's Catz flashed a brief thumbs-up when asked how the meeting went.
