Meta Enterprise Platform: Meta Hires MongoDB's CEO

Meta has created Meta Enterprise Platform, a new business unit to sell its artificial intelligence technology to businesses and developers, and has hired Chirantan “CJ” Desai, who until Monday was CEO of MongoDB, to lead it. Mark Zuckerberg announced the move on September 28, 2026, in the company’s newsroom, describing it as the next great pillar of Meta’s business, alongside its social networks and advertising.

Meta Enterprise Platform in 20 seconds

Meta is creating a division to sell its AI stack to businesses.
It will start with the Muse agent, Meta Business Agent, Muse API, and Muse Code.
It will be led by CJ Desai, who leaves MongoDB after less than a year at the helm.
Meta hasn’t given pricing, availability dates, or named customers.

Desai will hold the title of Chief Enterprise Platform Officer and will report directly to Zuckerberg. Before MongoDB, he led product and engineering at Cloudflare and spent nearly eight years at ServiceNow, where he rose to president and chief operating officer. Zuckerberg highlighted his ability to build complete enterprise software and his extensive industry network, which Meta hopes to tap into.

What Meta wants to sell businesses

The announcement is short and describes an intention more than a closed catalog. According to Zuckerberg, Meta Enterprise Platform will lean on advantages few companies can match: advanced models, agents, infrastructure at scale, and years of work with businesses, advertisers above all. In its first phase, it will bring businesses and developers its “full technology stack,” with four products named specifically and an “and more” that leaves the list open.

Those products already existed separately. Muse is Meta’s model family and assistant, which the company debuted in April with Muse Spark, and whose version 1.3 arrived in early September, according to SiliconANGLE. Muse API gives developers access to those models. Muse Code is the coding agent Meta launched in August to compete with tools like Claude Code. Meta Business Agent, unveiled in June, is an agent that handles customer inquiries on behalf of businesses, for example through WhatsApp.

What’s new is bringing it all together under a single division, with a top-level executive in charge and the goal, in Desai’s words, of turning Meta’s AI stack into products and services that companies can deploy in their own business. Desai adds that security and privacy are built into Meta’s enterprise products from the start, pointing to the security approach the company has published for Muse. SiliconANGLE cites among those measures an isolated environment, Muse Confidential VM, which Meta plans to roll out later in 2026 and which would prevent the company itself from accessing the contents of each instance.

What the announcement doesn’t say carries as much weight as what it does. There’s no pricing or availability dates, no reference customers, and no information on which countries will be able to buy these services, a relevant detail for European businesses. It also doesn’t clarify whether Meta will sell directly or through partners. This isn’t the first time Meta has tried to break into enterprise software: in 2024 it announced the shutdown of Workplace, its internal communication tool for organizations.

MongoDB suddenly loses its CEO

The hire comes at a clear cost to MongoDB. The database company announced on the same September 28 that Desai was stepping down effective immediately to join Meta. He’s being replaced on an interim basis by Dev Ittycheria, who was CEO himself between 2014 and 2025 and who, according to the company, grew its annual revenue from about $35 million to more than $2.3 billion. Ittycheria had remained on the board of directors, which has hired an executive search firm to find a permanent replacement.

Board chair Tom Killalea said MongoDB’s business “is strong,” and the company reaffirmed the third-quarter and full fiscal-year 2027 guidance it had published on September 1. Even so, the market reacted harshly. TechCrunch reported a drop of more than 17%, SiliconANGLE put it at more than 18%, and Quartz went as high as 25% at one point; the discrepancy is likely explained by when during the trading session each figure was taken. Quartz also reported a roughly 4% drop in Meta’s shares.

Desai had been MongoDB’s CEO for less than a year, a period in which the company steered much of its product roadmap toward AI agents, including the addition of embeddings and reranking to Atlas, announced in August.

Looking for revenue to match a massive investment

Meta doesn’t explicitly tie the two together in its announcement, but the new division arrives as the company faces pressure to show its AI spending is paying off. In July, Meta defended an investment of up to $145 billion in AI despite its falling cash flow. So far, that spending has mostly translated into better advertising and free products for users, while OpenAI, Anthropic, Google, and Microsoft have already been selling models and agents to businesses for some time.

Zuckerberg argues that superintelligence will create new opportunities for people and businesses, and that Meta already helps hundreds of millions of businesses reach their customers. Desai goes further, setting a goal of making Meta the place businesses turn to in order to grow. Those are goals, not results. It remains to be seen how an enterprise offering built on models Meta develops mainly for its own services will fit in, and how it will be received by companies that have already chosen an AI provider.
