Key highlights:
MongoDB stock dropped sharply after the software company’s CEO, Chirantan “CJ” Desai, resigned to take a role at Meta Platforms. Shares crashed more than 26% in early trading on Monday before ending the day down 19%.
Desai led MongoDB for less than a year after joining in November 2025. He is taking on a newly created position at Meta called chief enterprise platform officer, where he will report to CEO Mark Zuckerberg.
Desai’s exit rattled MongoDB investors badly
The stock drop wiped out about $8 billion in the firm’s market value in a day. That figure is more than three times its entire revenue for the last fiscal year, which came in at $2.46 billion.
Desai’s new job at Meta explains a part of why investors reacted so strongly. He will be running Meta’s new Meta Enterprise Platform, a business unit that would sell its AI models, agents, and infrastructure to companies.
In a statement, Desai said his goal is to make Meta “the place enterprises come to scale their businesses.” This sounds a lot like what MongoDB hired him to do months ago, except he is now chasing that opportunity in a larger company.
Meta’s new platform will initially focus on a set of tools that includes Muse, its personal AI agent, along with a business agent and a coding tool. Muse has already seen rapid growth since launching this month. It climbed fast in App Store rankings and overtook OpenAI’s ChatGPT as the top free iOS app at one point.
Zuckerberg boasted about his company’s advantage, saying the company plans to lean on “strengths that few other companies have.”
Desai received an offer from Zuckerberg himself that he ultimately couldn’t turn down, CNBC reported. The offer was said to be strong enough that Desai chose to walk away from his pay package and severance at MongoDB to take it.
Former CEO returns to take the reins
To manage the transition, the firm’s board named Dev Ittycheria as interim president and CEO. Ittycheria had previously served as the firm’s CEO from 2014 to 2025. At the time, the company’s annual revenue grew from about $35 million to over $2.3 billion under his leadership.
Ittycheria shared his confidence in stepping back into the position.
“I’m honored to step back into the president and CEO role at MongoDB. I was privileged to lead the company for more than a decade and help build MongoDB into the global business it is today,” he said.
MongoDB’s Chairman of the Board, Tom Killalea, backed the choice to bring Ittycheria back, saying he “knows this company deeply, has remained an involved and active executive board member over the past year.”
The timing of the exit was not the most convenient
Apparently, Desai had told the board of his plan to resign on September 24, days before the news became public, according to a securities filing.
The timing, however, creates an awkward situation for MongoDB. The company is scheduled to hold its Investor Day on Tuesday, September 29. Investors had been expecting an update to the firm’s long-term growth plan. Now, an interim CEO will be the one presenting a strategy that was made under an executive who just left for a competitor.
The stock has lost almost a quarter of its market value so far in 2026. Monday’s drop adds to a difficult year for the company even as it continues reporting strong revenue growth.
