When the tech industry’s top executives head to Trump Tower this week for an invite-only meeting, they will have many things to say to Donald Trump. But they all share a single major agenda: Breaking the ice. Unlike President Barack Obama, who frequently visited Silicon Valley and hosted tech executives at the White House, the president-elect has had a bitter relationship with the industry. On the campaign trail, Trump chastised Apple for outsourcing the manufacturing of iPhone components in China and threatened to push federal intelligence agencies to weaken security software to fight terrorism. He vowed to curb immigration, a charged issue for an industry that recruits and sponsors thousands of immigrant engineers. Tech leaders weren’t shy about their views either: Eric Schmidt, the executive chairman of Google’s parent company, volunteered for the Clinton campaign. Tesla chief executive Elon Musk said Trump didn’t “seem to have the sort of character that reflects well on the United States.” Dozens of executives signed an open letter opposing his candidacy. But on Wednesday afternoon, at a meeting organized by Facebook board member and Trump transition team member Peter Thiel, along with Trump’s son-in-law Jared Kushner and his chief of staff Reince Priebus, the leaders of Apple, Facebook, Google, Amazon, Microsoft, and other technology giants will try to put the past behind them. The one-hour meeting has no formal or written agenda, according to people familiar with the matter, and no one has seen a complete list of invitees. The attendee list includes Apple CEO Tim Cook, Facebook Chief Operating Officer Sheryl Sandberg, Tesla CEO Elon Musk, Amazon CEO Jeffrey P. Bezos, Alphabet CEO Larry Page, Microsoft CEO Satya Nadella, Cisco CEO Chuck Robbins, IBM CEO Ginni Rometty, Intel CEO Brian Krzanich, and Oracle CEO Safra Catz. Catz, a Republican who met with the transition team last month, is the only member of the group known to have had a previous relationship with Trump. Technology executives see the meeting as somewhat of an olive branch, according to the people familiar with their thinking, who spoke on condition of anonymity to talk freely about a private event. While Trump has held numerous one-on-one meetings during his transition, this is the first roundtable with executives from a single industry, they pointed out. It’s unclear how far the olive branch will extend. For Bezos and Trump in particular, the disputes have felt more personal at times. Trump has said Bezos and Amazon of “getting away with murder, tax-wise.” Noting that Bezos owns The Washington Post, Trump has accused him of directing the Washington Post’s coverage of his campaign to help Amazon avoid taxes. A spokesman for Amazon declined to comment on Bezos’ presence at the meeting. Because the CEOs see Trump as a wild card, they’re turning to their staffs to prepare for a range of issues that he could raise. Their staffs, in turn, are actively trading notes with one another. Trump and Silicon Valley are largely aligned on this subject. Trump has consistently said he plans to lower the corporate tax rate from 35 to 15 percent. Indeed, many in Silicon Valley who personally detest Trump have acknowledged that his anti-regulatory policies will make it easier for startups to launch products in new areas. Trade is the most heated topic the technology leaders plan to bring up. Many Silicon Valley companies are concerned with how imports of widgets and other technology hardware components from China and other countries will be taxed in a Trump administration. Trump’s populist vows to tear up trade deals, impose punitive tariffs on Chinese goods, and end an era of free trade have rattled the industry, along with other manufacturers that are dependent on cheap imports to manufacture their products. China is the United States’ largest trading partner.
