Mark Zuckerberg announced on Monday that Meta now has three pillars: the family of apps, the advertising engine, and — starting today — the Meta Enterprise Platform. As of Monday afternoon, the third one was a press release. The initial product line-up of the Muse agent, Meta Business Agent, Muse API and Muse Code was named but not launched, and Meta disclosed no pricing, no enterprise launch date, no named customers and no regional availability.
What Meta did ship is a hire. Chirantan "CJ" Desai joins as chief enterprise platform officer, reporting directly to Zuckerberg and leading the initiative. Desai was CEO and president of MongoDB for less than a year, from November 2025; before that he was president of product and engineering at Cloudflare from October 2024, and spent nearly eight years at ServiceNow, where he served as president and chief operating officer. Zuckerberg cited Desai's record in AI, infrastructure, business applications and security. Desai's own framing was careful: "As with Muse, security and privacy are built into Meta's enterprise products from the outset. Our goal is to make Meta the place enterprises come to scale their businesses."
The market's read arrived within hours. MongoDB shares fell roughly 18% on losing its chief executive, and Meta's own stock declined about 4.3%. Investors have been waiting for a return on Meta's AI spending: the company guided 2026 capital expenditure to \$130–145 billion, with more than \$100 billion of that aimed at AI infrastructure, and an enterprise business billed to companies is the clearest route to revenue beyond advertising.
The consumer base is genuinely there — the enterprise pitch is the leap. Muse launched on September 8 as a personal agent that handles email, travel bookings, payments and shopping, and it climbed to the top of the US App Store's free chart, with app-analytics firm Apptopia putting it at roughly 600,000 daily active users in the United States. Muse is the proof point Zuckerberg is selling to chief information officers. It is not, by itself, an enterprise product.
The track record is the harder problem. Meta shut down Workplace in June 2026 after a ten-year run, with roughly 7 million paying users and growth flat since 2021, and discontinued Horizon Workrooms in February 2026. Former Workplace vice president Julien Codorniou has described Meta's original enterprise entry as "an accident," adding: "You can't do enterprise SaaS as a side gig." An Oppenheimer survey of 1,500 US consumers found that only 8% would trust Meta with their passwords, against 30% for Google and 23% for Apple — a number that matters a great deal when the product is an autonomous agent with access to corporate systems.
Muse's own security record will follow it into the sales cycle. Columnist Jason Aten reported that the agent surfaced a topic drawn from a private conversation it had not been given access to; security researcher Patrick Wardle found a macOS zero-day that let malicious code already on a machine hijack the agent and expose dictated audio, account tokens and connected services, which Meta patched within 16 hours; Amazon blocked Muse from shopping on its platform. Meta's own documentation states the current Muse architecture "does not prevent Meta from accessing data when necessary to support, secure or operate the service" — the same page Desai linked to in his announcement.
Meta is also entering a market where the plumbing has largely been claimed. Microsoft made Entra Agent ID mandatory for new Copilot Studio agents in July 2026; Google's Gemini Enterprise agent platform ships Agent Identity, an Agent Registry and an Agent Gateway; Salesforce's AIforce includes an AI control plane and MuleSoft Agent Fabric; SAP's AI Agent Hub governs agents regardless of vendor; and Nvidia has just moved agent containment into silicon with its Open Agent Safety Platform and a coalition of more than 100 organizations. Those competitors have shipped identity management, audit trails and compliance tooling. Meta has announced them.
Demand, at least, is not in question. A KPMG survey of 314 US executives at companies with \$1 billion or more in revenue found that 62% were building, developing or deploying AI agents. Meta's real advantage is distribution: its business agents already sit inside WhatsApp, Instagram and Messenger, where millions of advertisers and hundreds of millions of businesses talk to customers. The harder task for Desai is that advertisers and the engineering teams who buy coding tools are different buyers, and Meta is asking one sales organisation to win both — while convincing IT departments that this time the pillar will still be standing in three years.
