Database software firm MongoDB's Chirantan "CJ" Desai has stepped down as president and CEO to join Meta Platforms as chief enterprise platform officer, the companies said on Monday.

Shares of MongoDB fell 14% in premarket trading.

Desai has served as MongoDB's CEO for less than a year, having taken the role in November from Dev Ittycheria.

MongoDB's board has appointed Ittycheria as interim president and CEO. It is searching for a permanent CEO and has retained an executive search firm to assist in that process.

"CJ is an experienced enterprise leader with a track record of building full-stack software and delivering results in AI, infrastructure, business applications, and security. He has an extensive industry network that we look forward to partnering with. CJ joins us from MongoDB, where he was CEO and President. Before that he led product and engineering at Cloudflare and spent nearly eight years at ServiceNow, including as President and COO," Meta CEO Mark Zuckerberg said in a post on X.
