Meta hires MongoDB CEO CJ Desai, sending shares of data services company down

MongoDB CEO CJ Desai is joining Meta Platforms as its chief enterprise platform officer and will report directly to Meta CEO Mark Zuckerberg.

Desai, who was in his role at MongoDB for less than a year, will be leading the social media giant's new Meta Enterprise Platform for businesses, according to a release.

The new platform will initially prioritize a suite of tools that includes its new Muse agent, business agent and a coding tool.

Meta plans to use "strengths that few other companies have: advanced models, leading agents, large-scale infrastructure, and years of working closely with many businesses," CEO Mark Zuckerberg wrote in a release.

The news sent shares of MongoDB plummeting 24%.

The MongoDB board has named Dev Ittycheria as interim president and CEO. Desai took over from Ittycheria, who served as CEO for 11 years, in November 2025. He previously served as president of product and engineering at Cloudflare.

Desai's transition comes as Meta undergoes a massive pivot and bets big on new AI tools. For months, investors have demanded a payoff from the company's hefty AI investments as the social media platform maker shells out billions on new infrastructure.

Last week, the company's push into the AI agent market with its Muse personal AI assistant garnered massive consumer demand, overtaking OpenAI's ChatGPT as the leading free iOS app.

At the same time, a heated battle is unfolding in both Washington and Silicon Valley after top AI researchers and tech leaders, such as Anthropic's Dario Amodei, called for a development slowdown amid mounting concerns over AI safety.
