Meta moved into the business-software market on Monday, unveiling “Meta Enterprise Platform,” a new unit whose job is to sell the company's AI stack to corporate customers — and handing the reins to the man who ran MongoDB.

Chirantan “CJ” Desai resigned as MongoDB's president and CEO to become Meta's chief enterprise platform officer, reporting directly to Mark Zuckerberg. Meta said the unit will package Muse, the personal AI assistant it launched earlier this month, together with Meta Business Agent, the Muse API and Muse Code, for businesses and developers.

“Over the coming years, AI will fundamentally redefine how organizations of all sizes innovate, grow, serve customers, and run business operations,” Desai said. “Meta Enterprise Platform will focus on turning its AI stack into products and services that companies can deploy for their own businesses.”

The move is a bet that Meta can turn a sprawling AI build-out — and mounting investor pressure over its spending — into recurring enterprise revenue. The company already sells advertising to millions of businesses; now it wants to sell them software.

The shock landed on MongoDB. The database maker's shares fell by double digits, down more than 17% and as much as roughly 24% in premarket trading, and the company named Dev Ittycheria — who previously held the job — as interim CEO while its board searches for a permanent replacement. Desai's departure was effective immediately.

For Meta, the hire imports enterprise-sales experience into a company whose AI story has so far centred on consumers and advertisers. It also raises a question businesses will have to answer for themselves: how much they trust a vendor whose consumer assistant, Muse, has already faced scrutiny over trust and privacy.
