Meta launches Meta Enterprise Platform on Muse models, led by ex-MongoDB CEO Desai
On Monday, Meta CEO Mark Zuckerberg announced an enterprise services business built on Meta's Muse models and agent harnesses. It is called the Meta Enterprise Platform. The Register, which reports the story with a sharply critical edge, frames it as Meta's search for profits "at the bottom of the AI rabbit hole".
The background is money. Meta's online businesses, excluding virtual reality, earned $50.3 billion in profits in the first half of 2026, essentially all from advertising. Ad revenue over the same period was $114.4 billion. Meta gathers data about users through its social networking and messaging services and uses AI-powered recommender systems to serve targeted ads. It has also edged toward having LLMs write those ads, and imagines AI managing some aspects of advertisers' businesses, such as responding to customer inquiries.
The new platform is meant to earn from more than the fact that businesses cannot avoid having a presence on Meta's social media properties. In addition to companion agents, Zuckerberg sees opportunities to sell business agents and coding agents, and even to power customer applications through Meta's API platform. In a Facebook post he wrote: "Initially, we will focus on bringing our full technology stack, including the Muse agent, Meta Business Agent, Muse API, Muse Code, and more to businesses and developers to help them grow."
The move puts Meta in competition not only with other model builders but with Microsoft, Amazon and Google, which the article says have a head start in bringing AI-powered services to enterprise customers.
Chirantan "CJ" Desai leads the effort. He quit as CEO of MongoDB on Monday to take the Meta job. His task is to convince enterprises to embrace Meta, an idea that flopped in 2016 when the company introduced Facebook At Work, a version of its social networks tuned for internal collaboration.
The Register argues that trust is the obstacle. Microsoft, Amazon and Google have endured various scandals, but the article calls them established B2B players with rap sheets rather shorter than Meta's. It notes that Meta recently agreed to an $18 billion settlement over allegations that it used features that harmed children's health, and calls that the tip of an iceberg that includes smart glasses, age-inappropriate chatbots and the Cambridge Analytica scandal. Its closing line says Zuckerberg now wants readers to believe Meta has grown up and can be trusted with all their AI needs.
Key facts
- Meta CEO Mark Zuckerberg announced the Meta Enterprise Platform on Monday, an enterprise services business built on Muse models and agent harnesses.
- Chirantan "CJ" Desai, who quit as CEO of MongoDB the same day, leads the enterprise push.
- Zuckerberg's stack includes the Muse agent, Meta Business Agent, Muse API and Muse Code, aimed at businesses and developers.
- Meta's online businesses earned $50.3 billion in profit in the first half of 2026 on $114.4 billion of ad revenue, essentially all advertising.
- The Register says Meta faces rivals with a head start (Microsoft, Amazon, Google) and a reputation problem, including a recent $18 billion settlement over children's health allegations.
Why it matters
Meta's income is almost entirely advertising: $50.3 billion in profit and $114.4 billion in ad revenue in the first half of 2026. An enterprise platform built on its Muse models is a bid to sell AI to businesses directly, not only to show ads to their customers. It also sets Meta against Microsoft, Amazon and Google in enterprise AI, where The Register says those companies are ahead.
Who it affects
Businesses and developers are the stated targets: Zuckerberg says the initial focus is bringing the full technology stack, including the Muse agent, Meta Business Agent, Muse API and Muse Code, to them. Enterprise buyers now have another vendor to weigh against Microsoft, Amazon and Google. Advertisers are also in the picture, since Meta imagines AI handling parts of their operations, such as answering customer inquiries.
How to use it
The source does not describe how to get access. No pricing, launch date or availability timeline for the Meta Enterprise Platform or its products is given, and no named customers or partners are mentioned. What is named is the product set: the Muse agent, Meta Business Agent, Muse API and Muse Code.
How solid is it
The announcement itself is solid: Zuckerberg made it on Monday and wrote about it in a Facebook post, and Desai's move from MongoDB is reported as happening the same day. The details are thin. The Facebook post is quoted only in part, and no size of investment or revenue targets is given. The article is The Register's take, with its own commentary and opinion layered over the news, so the judgments about Meta's trustworthiness are the author's, not established fact.
Risks and caveats
The Register points to Meta's history in this market: Facebook At Work flopped in 2016. It also argues that trust is a burden, citing an $18 billion settlement over allegations of features that harmed children's health, and a list of other controversies including age-inappropriate chatbots and the Cambridge Analytica scandal. The article says rivals have shorter rap sheets. No reason for Desai's departure from MongoDB is given, and no MongoDB reaction or successor is mentioned.
