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,” Zuckerberg wrote in the release.
The news sent shares of MongoDB plummeting 16%. Meta’s stock declined about 4%.
The MongoDB board named Dev Ittycheria as interim president and CEO. Desai took over from Ittycheria, who served as CEO for 11 years, in November 2025. Desai previously spent a year as president of product and engineering at Cloudflare. He also worked as operating chief at enterprise software maker ServiceNow.
Desai’s transition comes as Meta undergoes a massive pivot, betting big on new artificial intelligence products and services for its enterprise customers. Amid this transition, investors have demanded a payoff from the company’s hefty AI investments on new infrastructure and tools.
The social media giant’s push into the AI agent market with its Muse personal AI assistant has seen a rush of 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.
MongoDB has shed nearly a quarter of its market value in 2026.
