Meet the Silicon Valley billionaires, founders, and investors backing Kamala Harris

The billionaire, Shark Tank star, and former principal owner of the Dallas Mavericks is one of the most well-known signatories. Valued at $5.4 billion according to Forbes, Cuban voted for Nikki Haley in the 2024 GOP primaries but later attended a Biden fundraiser, ABC News reported.

He vowed to support Biden after his disastrous debate performance but said hewas interested in whether other Democrats were better positioned to beat Trump. He was one of the quickest to react when Biden dropped his reelection bid, writing on X, "Father time is undefeated."

Cuban has retweeted various posts about Harris' campaign, including one saying that Democrats had "some well-needed momentum." He anticipates that she will be more open to business, artificial intelligence, and crypto, Politico reported.

Reid Hoffman, a LinkedIn cofounder and longtime Democratic donor, wasted no time throwing his weight behind Harris, offering his support for her campaign the same day that Biden ended his. Of the president, he said that dropping out was "one of the most selfless acts we've seen from a politician in modern American history."

In January, Hoffman poured $2 million into a super PAC that led a write-in campaign in New Hampshire for Biden's campaign. The Information first reported that Hoffman pushed Reed Hastings, Netflix chairman, to donate $7 million to a PAC supporting Harris.

He has openly sparred with business and tech leaders, namely David Sacks, who support Trump. He plans to host a fundraiser for Harris.

The OpenAI investor and founder of Sun Microsystems was quick to back Harris after an initial post on X in support of Michigan Gov. Gretchen Whitmer or Pennsylvania Gov. Josh Shapiro. Khosla, who endorsed Hillary Clinton in 2016, hosted a fundraiser for Biden in May and has donated to various Democratic candidates and super PACs.

Khosla has said on X he would not support a candidate who denies the outcomes of elections, is in favor climate policy and regulations on emissions, and supports growth-oriented economic policy.

He has been outspoken about his views contrary to other leading tech executives.

Khosla engaged in a heated exchange with Elon Musk on X the day Biden ended his 2024 campaign in which he said there was "no reason to accept depravity in his personal values."

"Hard for me to support someone with no values, lies, cheats, rapes, demeans women, hates immigrants like me," Khosla replied to Musk on X.

The venture capitalist who runs the venture firm SV Angel is a longtime Kamala Harris donor who has contributed to liberal PACs and campaigns for local Democratic leaders. Conway is known for his philanthropic contributions to the UCSF Medical Center and Children's Hospital and other organizations protecting firearm safety, rights for trans youth, and immigration reform.

"She is thoughtful and collaborative, able to bring people together to solve difficult problems and accomplish critical goals," Conway wrote about Harris on X. "She is also a fighter — for justice, fairness, and prosperity. She has proven all of that throughout her career and as vice president, and she will prove it again as the democratic nominee and as the 47th President of the United States."

A founder of and general partner at venture capital firm Moxxie Ventures, Stanton has graced Forbes' list of the most powerful women in technology. She was formerly Twitter's vice president of international strategy.

When Biden dropped out, she called him a "hero" on X and listed many candidates who could replace him, with Harris as the first name on her list. She quickly expressed her support for Harris on the platform, reposting a video of her and saying that she is "fired up and ready to vote."

Shortly after Biden dropped out, Stanton told the New York Times that most of Silicon Valley does not support Trump, despite Elon Musk and others' endorsements for the former president.

"You have people with the loudest voices claiming to speak for the broader community, and the views don't match," she said. "By no means do they line up with the thousands of founders and employees and investors who live and work in Silicon Valley."

The venture investor behind the VC firm Lowercase Capital has long opposed Donald Trump and backed Hillary Clinton's campaign in 2016. Sacca donated $150,000 to the ACLU after Trump signed an executive order temporarily restricting the admission of citizens from seven countries. Sacca also worked for Barack Obama's 2008 and 2012 campaigns.

Despite saying that he "hates politics" on his website, he noted that he and his partner Clay Dumas have "invested millions of dollars and countless hours helping build organizations and companies that we think have the best shot at giving blue candidates an edge in a game that is rigged against them." He advocated donating to Biden's campaign before he dropped out.

The Cowboy Ventures founder and VC angel investor coined the term "unicorn" and cofounded the nonprofit All Raise to advocate for women in venture capital.

Though Lee hasn't written much publicly about her support for Harris, she responded to a conservative activist suing a VC firm supporting Black women owners last year on LinkedIn, writing, "With every opportunity we have - let's vote in folks who are going to create and support more opportunities for economic empowerment and achievement, not spend their energy trying to crush opportunities for deserving, under represented folks."

In addition to being the managing director at Insight Partners, a global venture capital and private equity firm, Parekh is a philanthropist and Democratic donor. He was included on the guest list for the White House State Dinner in June 2023, and he was a key fundraising organizer for Democrats during the 2018 midterms, the New York Times reported.

Though Parekh has been relatively quiet online in recent weeks, he did retweet an announcement that Salman Rushdie, an author, had endorsed Harris.

Suster is a well-known face in the Los Angeles venture capital scene, where he is a partner at the firm Upfront Ventures. He thanked Biden for dropping out in a post on X and has reshared various statements from Harris. In particular, he has posted about her stance on Israel and her condemnation of Hamas.

In his role at Upfront, Suster oversees more than $3 billion in assets and has enmeshed himself in the LA tech world.
