Meta hires MongoDB's CEO to sell its weeks-old Muse agent to businesses

Whoever gets asked this week whether their company should try Meta's agents has a short file to work from. Most of it is Zuckerberg's post on X and the reporting around it ^[1]. The pitch in that file is large. Zuckerberg wrote that Meta is "starting the next major pillar of our business" ^[2]. TechCrunch noted that the unit could help Meta earn a return on the money it is pouring into AI ^[19].

What Meta actually did on Monday was hire someone, and the hire is the part a buyer can check ^[3]. Desai spent nearly eight years at ServiceNow, including as president and chief operating officer ^[8]. He then led product and engineering at Cloudflare ^[7] before taking over MongoDB. MongoDB's shares fell on the news. Business Insider reported a drop of as much as 27% on Monday ^[9], while TechCrunch put it at more than 17% ^[10].

Desai's case for Meta rests on the customers it already has. "Meta has a unique role to play because it is bringing together advanced models and leading agents with a proven track record of helping millions of advertisers and hundreds of millions of businesses scale," he said in a statement ^[12]. By his own description, what those businesses get from Meta today is help to scale. What the unit expects them to buy next is software they run themselves. He said it "will focus on turning its AI stack into products and services that companies can deploy for their own businesses" ^[11].

So far there is little evidence that companies want that software. Muse had been public for less than a month when Meta started offering it to businesses ^[17]. Investors are betting on the agent, and Meta's shares rose 11% last week ^[15]. That rise measures what investors expect. The reports do not include retention or usage figures for Muse, and those are the numbers that would show whether anyone keeps using it.

A two-by-two sorts the decision for a given company. One axis is whether it already does business with Meta ^[12]. The other is whether the job is agent work in front of its own customers or developer work through the API and coding products ^[5]. The pitch fits best for existing Meta customers with customer-facing work. For them, the first thing to settle is Reuters' report that Meta has been testing human callers behind Muse ^[16]. Existing customers with developer work can run a small test once Meta publishes a price. A company with no Meta relationship and customer-facing work faces the heaviest diligence, because the agent is less than a month old ^[17]. A company in neither group can wait for a price list and compare it with what it already pays.
