MongoDB has announced a leadership transition, with Dev Ittycheria stepping down as CEO and Chirantan "CJ" Desai taking over the position effective November 10, 2025. Dev, who expressed a deep connection to MongoDB and its people, decided not to commit to another five-year term, leading to a search for a suitable successor. CJ Desai, who previously held significant roles at ServiceNow and Cloudflare, was selected for his extensive experience in scaling technology companies and his personal qualities, which include humility and a willingness to learn. The transition is part of MongoDB's strategic evolution, dubbed "MongoDB 3.0," and aims to leverage emerging opportunities in AI and data-intensive applications. While Dev plans to remain on the Board and support CJ during the transition, he looks forward to spending more time with his family and remains confident in MongoDB's future, emphasizing the importance of timely change for sustained growth. An all-hands meeting is scheduled to introduce CJ and address questions, reinforcing that this transition marks the beginning of a new chapter for MongoDB.
