Meta Hires MongoDB CEO, Launches Enterprise AI Business

On September 28, Meta announced the launch of Meta Enterprise Platform, a new enterprise AI unit, and hired Chirantan "CJ" Desai, until now the chief executive of MongoDB, to run it. Desai's title is Chief Enterprise Platform Officer, and he reports directly to CEO Mark Zuckerberg. The same day, MongoDB disclosed that Desai had stepped down effective immediately, and its shares plunged 18%, according to reports.

In a post on Meta's newsroom, Zuckerberg called the business the company's "next major pillar." "Superintelligence will create significant new opportunities for all people and businesses," he wrote, noting that Meta already serves billions of people and helps hundreds of millions of businesses reach customers. A company that has dealt with businesses mainly through advertising is now declaring that it will sell AI technology itself to them.

According to the Meta announcement METAL reviewed, the first step is to open Meta's full technology stack to businesses and developers. The products named are the personal agent Muse, Meta Business Agent, Muse API and the coding tool Muse Code. Zuckerberg listed four strengths "that few other companies have": advanced models, leading agents, large-scale infrastructure, and years of working closely with many businesses.

The foundation is Muse's run this month. In early September, Meta released Muse, a personal AI agent that shops, books travel, sends email and makes payments on a user's behalf. According to reports, Muse overtook ChatGPT in the App Store's free rankings, and some analysts have described it as the biggest US app launch since ChatGPT in November 2022. METAL has reported on how Muse leads with trust through a secure virtual machine design, and Desai said the same principle will apply to the enterprise products.

"Over the coming years, AI will fundamentally redefine how organizations of all sizes innovate, grow, serve customers, and run business operations," Desai said in a statement. He said the new unit will focus on turning Meta's AI stack into products and services that companies can deploy for their own businesses, adding, "As with Muse, security and privacy are built into Meta's enterprise products from the outset." The goal, he said, is "to make Meta the place enterprises come to scale their businesses."

The hire's résumé shows what Meta is buying. Desai spent nearly eight years at ServiceNow, including as President and COO, and led product and engineering at Cloudflare. He became MongoDB's CEO in November 2025, so his tenure lasted less than a year. Zuckerberg introduced him as an enterprise leader with a record of building full-stack software and delivering results in AI, infrastructure, business applications and security, and said he looks forward to partnering with Desai's "extensive industry network." A consumer app company has brought in, wholesale, someone who knows the grammar of enterprise sales.

MongoDB moved quickly to contain the fallout. The board appointed Desai's predecessor, Dev Ittycheria, as interim President and CEO. Ittycheria led the company for 11 years, from 2014 to 2025, growing annual revenue from about $35 million to more than $2.3 billion. "MongoDB's business is strong, and there is no better person to take on the role of President and CEO in the interim than Dev Ittycheria," said board chairman Tom Killalea. "I was privileged to lead the company for more than a decade," Ittycheria said, adding that he would move quickly and execute with focus.

The company has retained an executive search firm to find a permanent CEO and said it is reaffirming the guidance for the third quarter and full fiscal year 2027 that it issued on September 1. Its Investor Day will go ahead as planned on September 29 at the Nasdaq MarketSite in New York. MongoDB has more than 70,000 customers, and about 75% of the Fortune 100 use its database.

The market's verdict was split. According to reports, MongoDB shares fell 18% on the day of the announcement and Meta's slipped about 4%, with MongoDB having already lost roughly a quarter of its market value this year. Brokerage Piper Sandler wrote in a note, "While the departure is disappointing, we believe MongoDB remains well-positioned strategically and view the share-price reaction as overdone." Reports also pointed to investors' demands for a payoff on Meta's heavy AI infrastructure spending as backdrop to the announcement.

Through a journalist's lens, the weight of this announcement lies in the person rather than the product. The new unit's product list is largely a bundle of the Muse lineup already on the market, and the announcement gives no pricing, launch schedule or first customer. By contrast, pulling a sitting public-company CEO overnight and placing him directly under the founder is itself a signal of how urgently Meta views the enterprise market. With models and agents already in hand, the missing piece was someone who knows how to get through corporate procurement and security reviews.

Desai cited as Meta's differentiator, beyond advanced models and agents, its track record of helping millions of advertisers and hundreds of millions of businesses grow. Meta's calculation is to carry its consumer AI success over that network of relationships into enterprise revenue, while MongoDB has filled the gap by calling back its former CEO. The next steps for both companies will become visible at MongoDB's Investor Day on the 29th and when Meta names its first enterprise customer.
