According to Meta, CJ Desai will take the role of chief enterprise platform officer, with CEO Mark Zuckerberg as his direct manager. Investors reacted fast: MongoDB fell 20% after the announcement, while Meta eased about 4%.
Desai had been in the CEO seat at MongoDB for under a year, having taken over from Dev Ittycheria in November 2025. The board has now put Ittycheria back in as interim president and CEO. Ittycheria previously ran MongoDB for 11 years before stepping aside. Before MongoDB, Desai served as Cloudflare's president of product and engineering.
Desai will run the new Meta Enterprise Platform for business customers, with an initial slate featuring the Muse agent, a business agent, and a coding tool. "Strengths that few other companies have: advanced models, leading agents, large-scale infrastructure, and years of working closely with many businesses," is how Zuckerberg framed Meta's advantage. The hire lands as Meta reorients around enterprise AI, with investors pressing for returns on its heavy spend for infrastructure and tools. Meta's push into AI agents has momentum: consumer interest in its Muse personal assistant has spiked, and it now ranks ahead of OpenAI's ChatGPT among free apps on iOS.
