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.

“Initially, we will focus on bringing our full technology stack, including the Muse agent, Meta Business Agent, Muse API, Muse Code, and more to businesses and developers to help them grow,” the release states.

The news sent shares of MongoDB plummeting 17%.

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.
