Business leaders including Bill Ackman, David Sacks, and Jared Kushner, react to Charlie Kirk’s death

Hedge fund manager Bill Ackman made several X posts about Kirk’s death.

“I feel incredibly privileged to have spent a day and shared a meal with @charliekirk11 this summer. He was a giant of a man,” he wrote in an X post shortly after midnight on Thursday.

Venture capitalist David Sacks called Kirk the “best of America.”

“My friend Charlie Kirk was the best of America. A self-made man, a young husband and father, and a patriot, he was relentlessly positive about the future,” Sacks, who is also the White House’s AI advisor, wrote in an X post Wednesday evening.

Jared Kushner, a businessman who is married to President Donald Trump’s daughter, Ivanka Trump, said Kirk was a “special human being.”

In a Wednesday evening X post, he said Kirk had greatly aided Trump’s 2016 presidential campaign and helped build the MAGA movement.

“The world lost a powerful force today, way before his time,” Kushner wrote.

Garry Tan, the CEO of Y Combinator, responded to news of Kirk’s death in an X post on Wednesday evening.

“No matter what your politics might be, or what you believe about how society should be structured, it is truly a sad day today that someone who spoke their mind would be killed for it,” Tan said.

Amjad Masad, the CEO of the software company Replit, wrote in an X post on Wednesday evening that he was “shocked and saddened by the shooting of Charlie Kirk.”

“I didn’t know him well, but after my podcast with Tucker aired, he reached out through a mutual friend with kind words — a gesture that stayed with me,” he wrote.

He sent condolences to Kirk’s family.

Shaun Maguire, a partner at Sequoia Capital, made a series of X posts expressing his shock over Kirk’s death. He called Kirk a “personal friend.”

Maguire first posted about it shortly after the shooting, calling Kirk an “American hero” and a “titan.”

“We love you Charlie. You were a warrior and a leader. History will be very kind to you down here on Earth. We will take care of your family,” he wrote in a later post.

At about 6:30 p.m. on Wednesday, he wrote of Kirk, “We lost a future President.”
