Each year, Salesforce updates its V2MOM, a planning document laying out vision, values, methods, obstacles and measures. CEO Marc Benioff has said it’s “been used to guide every decision at Salesforce” since the software company’s founding 25 years ago this week.
But in early 2023, there was a problem. ChatGPT was going viral, and Salesforce’s strategy didn’t account for it.
“The V2MOM had nothing about generative AI,” Parker Harris, who co-founded the company with Benioff, told CNBC in an interview.
It was a first for Salesforce, which had never been caught so off-guard about an emerging technology trend. If Salesforce was to become a leader in generative artificial intelligence, the company would need to quickly revise its guiding document to redirect the company — and its 73,000 employees — toward the technology that’s sweeping across Silicon Valley and making its way into every industry, from manufacturing to medicine.
Salesforce would have to go to battle with tech giants Amazon, Google and Microsoft, as well as red-hot and well-capitalized startups. But following a handful of hefty acquisitions and a run-in with activist investors that led Salesforce to disband its M&A committee, a splashy deal was likely off the table.
Salesforce would have to build. And that’s when Benioff turns to his longtime sidekick, Harris.
Well known in the software industry but largely unfamiliar outside of it, Harris has always been core to the fabric of Salesforce. In the past six years, Benioff has elevated two different top lieutenants to the role of co-CEO, but neither lasted in the job longer than 18 months. Harris, a Salesforce board member and now the technology chief of Slack, which Salesforce bought in 2021, said he’d rather avoid the limelight.
“I don’t like being front and center,” Harris said, in an interview tied to the company’s 25th anniversary, which was officially March 8. “I don’t like the articles necessarily to be written about me. I like being behind the scenes.”
Internally, Harris is in the thick of it. After generative AI made its way into the revised V2MOM last year, Harris supervised its brisk insertion into the company’s sales, customer service, marketing and commerce applications. He studied new techniques such as retrieval-augmented generation, which involves feeding information outside of an AI model’s training set to yield a better answer.
Questions swirled about whether Salesforce should spend billions of dollars to assemble its own general-purpose large language model for spitting out text in response to a few words of human input, Harris said. But the company started seeing clients use multiple LLMs.
Salesforce slashed its investment in some areas while doubling the size of its research group, which was fleshing out its own AI models. At the same time, it started drawing on models from AI startup Anthropic, as well as GPT-4, the model powering OpenAI’s ChatGPT. In September, Benioff brought OpenAI CEO Sam Altman onstage at Salesforce’s annual Dreamforce conference, which takes over a chunk of downtown San Francisco.
At past Dreamforce shows, Harris has appeared in superhero costumes, entertaining the audience of tens of thousands. But 2023 was not a time for jokes. Harris was busy repositioning the company. He chose a professional look: a checked blue suit that matched his glasses with thin blue frames.

In his keynote, Harris talked about the Data Cloud, a product originally called Genie that surfaces real-time information. In about 2016 he had decided to push much of Salesforce’s IT infrastructure into the public cloud, enabling tighter integration of many assets the company had acquired over the years. That helped Salesforce launch the Data Cloud.
Without the Data Cloud, Harris told CNBC, “I think we would have been in a much worse place.” It’s such a critical part of the company that Benioff mentioned it 58 times on the company’s earnings call in February.
A Robin for Batman
Despite his status as the most decorated technical leader at one of the world’s largest software companies, Harris was an English major. He earned a bachelor’s degree from Middlebury College in Vermont.
His love of computers came early, though. He told Business Insider in 2015 that he started programming on an Apple II as a kid growing up in North Carolina.
In the early 1990s, he moved to the San Francisco Bay Area and took a software-engineering job at a company called Metropolis Software, where he got to know developers Frank Dominguez and Dave Moellenhoff. The trio founded a Java consulting firm called Left Coast Software.
They were contracting at Saba Software, an online learning company co-founded by former Oracle executive Bobby Yazdani. Benioff, who was still working at Oracle under Larry Ellison at the time, told Yazdani that he had this idea to build web-based sales software. Yazdani told Benioff he needed to meet Harris, Dominguez and Moellenhoff.
“He was a very abstract thinker,” Yazdani said about Harris, in an interview with CNBC. “He had clarity around capability of what’s possible.”
In the fall of 1998, Benioff and Harris met for lunch at Kincaid’s, a seafood and steak restaurant in Burlingame overlooking the San Francisco Bay. It was an uneven match. Benioff is hard to miss at 6 feet, 5 inches tall. He’s loud and loves to talk.
Harris is scrawny and quieter. He said he’s averse to conflict. He defuses the drama, said Brett Queener, a former Salesforce executive who’s now a venture capitalist.
“Every Batman needs their Robin,” Queener said.
After the lunch meeting, Benioff had Harris, Dominguez and Moellenhoff over to his home in San Francisco’s Telegraph Hill neighborhood. They were all in.
Salesforce.com was born on March 8, 1999. Harris was 32. His parents, wife and young daughter came by corporate headquarters — a one-bedroom apartment next to Benioff’s home — to commemorate the moment, which Harris posted to YouTube eight years later.
“We are going to probably work here for six months to a year, and we’re going to just really enjoy it,” he told his father, who was behind the camera. Salesforce played the clip for employees this week during a celebration.
While Harris shared the title of co-founder with Benioff, his partner held much more of the equity. That’s why Benioff is now worth around $11 billion, with a current stake in Salesforce that exceeds $7 billion, while Harris’ holdings are worth nearly $600 million.
Though he’s relatively soft spoken, Harris has his indulgences. He’s spent money on red wine from France and Italy, works of art by Ruth Asawa and Josef Albers, a home in Nantucket and a renovation of the family home in San Francisco’s Pacific Heights.
“We really shifted it to a focus on sunlight,” Harris said.
In his office at the top of the house, he likes to put on headphones and crank up the music. He listens to the Avett Brothers, Radiohead and Miles Davis. He plays golf and surfs. A coworker said Harris is an “enthusiastic” dancer. He belongs to Middlebury’s board of trustees.
At Salesforce, Harris led the development of the platform that enables companies to build on top of its software, along with an initiative to make Salesforce work well on mobile devices. There was also the push to build the next-generation Salesforce Lightning, as well as Chatter, an enterprise social network.
He talked about AI way back at Dreamforce 2009, suggesting that the technology might one day help Chatter identify in-house experts on different topics. He admitted to his shortcomings.
“I don’t understand that area,” Harris told a group of journalists, regarding AI. “I understand we have to solve it. I have hired some people in that area that do understand it.”
Tough time in social
At the time, social was the big buzzword. Facebook was still private but taking off.
A startup called Yammer was being described as the Facebook for the workplace. A few Salesforce employees started discussing the potential for information to go viral among salespeople and customer-service agents. Benioff was intrigued. He insisted that it become the top priority.
After Harris allocated eight engineers to the new project, Benioff demanded he go bigger. Harris checked in with engineering leaders and secured a headcount of 75.
That wasn’t enough. At a briefing on the updated status, Benioff was dissatisfied, according to a meeting attendee who asked not to be named to speak candidly about the matter. Harris was silent. His face went pale. He told Benioff he’d redo the plan, the person said.

Harris eventually got 80% of Salesforce’s engineers to start working on Chatter. But the product never took off.
“We didn’t take it far enough,” Harris said. Microsoft was also hot to get into the market, snapping up Yammer in 2012 for $1.2 billion, a huge multiple for a company with a small revenue base.
Salesforce wound up buying the big prize in the space, purchasing Slack in 2021 for $27.1 billion, by far the company’s priciest deal.
But perhaps Harris’ biggest swing in his decades at Salesforce was the push to the public cloud. It wasn’t an easy choice.
“Half the engineers, the brightest people, were like, ‘We’re going to run the company if we do this,'” Harris recalled. “The great fear was that we would ruin our cost model because the cost would be much more expensive on public cloud, and then we would be able to hire less salespeople or less engineers or whatever.”
The other half of the engineering staff, Harris said, was petrified that if Salesforce didn’t move to the cloud, everyone else will “innovate faster than us.'”
Benioff didn’t have much to contribute for a change.
“Marc was like, ‘This is crazy, that these are some of the smartest people I know, and you guys can’t agree,'” Harris said.

Harris saw the advantage that startups gained by outsourcing data center needs to Amazon Web Services. And he knew Salesforce had failed to build a viable platform for easily developing apps while partnering with VMware. Harris concluded that not pushing Salesforce to public cloud services like AWS would be an existential threat.
“That was a very lonely decision,” he said. But as it became a part of the V2MOM, it rippled out to thousands.
While Salesforce might have saved money when it ditched its Equinix colocation facilities, leaning more on the cloud hasn’t been cheap. Last year, after activist investors called for more profitability from Salesforce, the company signed up for longer-term cloud commitments. It agreed to spend at least $16.8 billion on infrastructure service providers as of January, up from $6.5 billion in January 2023, according to regulatory filings.
The biggest beneficiary of that spending is AWS, which is run by former Salesforce executive Adam Selipsky. Harris said Salesforce is looking at other providers as additional partners.
“Oracle has done a great job around their platform, so technically, it’s actually quite good,” he said.
‘Try to build something great’
Harris recently gave up the CTO title at Salesforce that he’d held for seven years. The company hasn’t yet named a successor.
Now he’s onto Slack.
In 2022, Slack CEO Stewart Butterfield left the company he founded in 2009. He was replaced by Lidiane Jones. She departed a year later to run dating app developer Bumble. And in January of this year, Slack co-founder and CTO Cal Henderson said he was stepping down.
“I thought, ‘I can have an impact there,'” Harris said. ‘But I can also — I would love to do that job, I would love to go back and run some engineering teams and really try to build something great.'”
Harris visited Benioff’s home in the Sea Cliff neighborhood of San Francisco, and the two co-founders were in agreement that it was the right call.
“I’m excited for this next chapter with Parker as Slack’s CTO, continuing his legacy as one of our industry’s greats,” Benioff said in an email.
Harris flew to New York to hang out with Noah Weiss, Slack’s product chief. Harris moved his desk to the Slack floor in San Francisco’s Salesforce Tower, where he’s near new unit CEO Denise Dresser. He comes in two to four days a week, and attends Monday meetings to review Slack metrics.
“People, probably fairly, had a lot of apprehension,” Weiss said.
Some of Slack’s employees suspected Harris would try to apply the Salesforce approach to Slack. But instead, Harris sought to understand how Slack had become successful.
Weiss said that at Salesforce’s new fiscal year kickoff in Las Vegas last month, Harris talked at an executive meeting about one of Slack’s product principles called prototype the path. And Harris has started writing documents in Slack’s collaborative Canvas tool.
“He’s been showing up extremely well, definitely winning hearts and minds, for sure, including mine,” Weiss said.
Employees sometimes add flair to Slack chats with a Parker Harris emoji, he said.
When it comes to keeping up with Benioff, who spends a healthy amount of time at his palatial estate in Hawaii, Harris uses other services.
“Marc is all mobile and all text and FaceTime,” Harris said.
The men talk once every few weeks. They’ll be talking more frequently, as Harris said they’re about to kick off weekly meetings on Slack and Salesforce integrations.
Harris hopes that his presence can convince Slack employees to stay after the executive exodus.
“I don’t want to talk too much about myself, but I think it is helping,” Harris said.

Silicon Valley executives and financiers publicly opened their wallets in support of President Donald Trump’s 2024 presidential run. The early returns in 2025 aren’t great, to say the least.
Following Trump’s sweeping tariff plan announced Wednesday, the Nasdaq suffered steep consecutive daily drops to finish 10% lower for the week, the index’s worst performance since the beginning of the Covid pandemic in 2020.
The tech industry’s leading CEO’s rushed to contribute to Trump’s inauguration in January and paraded to Washington, D.C., for the event. Since then, it’s been a slog.
The market can always turn around, but economists and investors aren’t optimistic, and concerns are building of a potential recession. The seven most valuable U.S. tech companies lost a combined $1.8 trillion in market cap in two days.
Apple slid 14% for the week, its biggest drop in more than five years. Tesla, led by top Trump adviser Elon Musk, plunged 9.2% and is now down more than 40% for the year. Musk contributed close to $300 million to help propel Trump back to the White House.
Nvidia, Meta and Amazon all suffered double-digit drops for the week. For Amazon, a ninth straight weekly decline marks its longest such losing streak since 2008.
With Wall Street selling out of risky assets on concern that widespread tariff hikes will punish the U.S. and global economy, the fallout has drifted down to the IPO market. Online lender Klarna and ticketing marketplace StubHub delayed their IPOs due to market turbulence, just weeks after filing with the Securities and Exchange Commission, and fintech company Chime is also reportedly delaying its listing.
CoreWeave, a provider of artificial intelligence infrastructure, last week became the first venture-backed company to raise more than $1 billion in a U.S. IPO since 2021. But the company slashed its offering, and trading has been very volatile in its opening days on the market. The stock plunged 12% on Friday, leaving it 17% above its offer price but below the bottom of its initial range.
“You couldn’t create a worse market and macro environment to go public,” said Phil Haslett, co-founder of EquityZen, a platform for investing in private companies. “Way too much turbulence. All flights are grounded until further notice.”
CoreWeave investor Mark Klein of SuRo Capital previously told CNBC that the company could be the first in an “IPO parade.” Now he’s backtracking.
“It appears that the IPO parade has been temporarily halted,” Klein told CNBC by email on Friday. “The current tariff situation has prompted these companies to pause and assess its impact.”
‘Cave rapidly’
During last year’s presidential campaign, prominent venture capitalists like Marc Andreessen backed Trump, expecting that his administration would usher in a boom and eliminate some of the hurdles to startup growth set up by the Biden administration. Andreessen and his partner, Ben Horowitz, said in July that their financial support of the Trump campaign was due to what they called a better “little tech agenda.”
A spokesperson for Andreessen Horowitz declined to comment.
Some techies who supported Trump in the campaign have taken to social media to defend their positions.
Venture capitalist Keith Rabois, a managing director at Khosla Ventures, posted on X on Thursday that “Trump Derangement Syndrome has morphed into Tariff Derangement Syndrome.” He said tariffs aren’t inflationary, are effective at reducing fentanyl imports, and he expects that “most other countries will cave and cave rapidly.”
That was before China’s Finance Ministry said on Friday that it will impose a 34% tariff on all goods imported from the U.S. starting on April 10.
At Sequoia Capital, which is the biggest investor in Klarna, outspoken Trump supporter Shaun Maguire, wrote on X, “The first long-term thinking President of my lifetime,” and said in a separate post that, “The price of stocks says almost nothing about the long term health of an economy.”
However, Allianz Chief Economic Advisor Mohamed El-Erian warned on Friday that Trump’s extensive raft of import tariffs are putting the U.S. economy at risk of recession.
“You’ve had a major repricing of growth prospects, with a recession in the U.S. going up to 50% probability, you’ve seen an increase in inflation expectations, up to 3.5%,” he told CNBC’s Silvia Amaro on the sidelines of the Ambrosetti Forum in Cernobbio, Italy.

Meanwhile, executives at tech’s megacap companies were largely silent this week, and their public relations representatives declined to provide comments about their thinking.
Microsoft CEO Satya Nadella was in the awkward position on Friday of celebrating his company’s 50th anniversary at corporate headquarters in Redmond, Washington. Alongside Microsoft’s prior two CEOs, Bill Gates and Steve Ballmer, Nadella sat down with CNBC’s Andrew Ross Sorkin for a televised interview that was planned well before Trump’s tariff announcement.
When asked about the tariffs at the top of the interview, Nadella effectively dodged the question and avoided expressing his views about whether the new policies will hamper Microsoft’s business.
Ballmer, who was succeeded by Nadella in 2014, acknowledged to Sorkin that “disruption is very hard on people” and that, “as a Microsoft shareholder, this kind of thing is not good.” Ballmer and Gates are two of the 12 wealthiest people in the world thanks to their Microsoft fortunes.
C-suites may not be able to stay quiet for long, especially if the recent turmoil spills into next week.
Lise Buyer, who previously helped guide Google through its IPO and now works as an adviser to companies going public, said there’s no appetite for risk in the market under these conditions. But there is risk that staffers get jittery, and they’ll surely look to their leaders for some reassurance.
“Until markets settle out and we have the opportunity to access valuation levels, public company CEOs should work to calm potentially distressed employees,” Buyer said in an email. “And private company managements should refine plans to get by on dollars already in the treasury.”
