What Happened to Dev Ittycheria?

Dev Ittycheria's journey with MongoDB has been marked by two distinct tenures as CEO, punctuated by a brief retirement and a swift return. He first took the helm as President and Chief Executive Officer in September 2014, leading the database company for an impressive 11 years. During his initial leadership, Ittycheria was instrumental in transforming MongoDB from an early-stage disruptor into a global technology leader, overseeing its successful Initial Public Offering (IPO) in 2017 and scaling annual revenue from approximately $35 million to over $2.3 billion.

In November 2025, Ittycheria announced his decision to retire from a full-time operating role, effective November 10, 2025. He communicated this as a personal decision, stating that he could not commit to another five years as CEO and felt the company was ready for a new leader with a fresh perspective. Despite stepping down from the CEO position, he remained an active member of MongoDB's Board of Directors and served as an advisor to his successor, ensuring a smooth transition.

Chirantan "CJ" Desai, formerly President of Product and Engineering at Cloudflare, was appointed to succeed Ittycheria as President and CEO, effective November 10, 2025. Desai was brought in for his extensive experience in cloud infrastructure, AI, and enterprise software, with the mandate to guide MongoDB's continued growth.

However, Desai's tenure proved to be unexpectedly short. On September 28, 2026, MongoDB announced that Desai had stepped down as President and CEO, effective immediately, to pursue a senior role at Meta Platforms, Inc. The company clarified that Desai's resignation was not due to any disagreements with MongoDB's operations, policies, or practices.

In a surprising turn of events, Dev Ittycheria was immediately reappointed as interim President and CEO, effective September 28, 2026. The Board cited his deep knowledge of the company and his continued involvement as an executive board member as key reasons for his interim return, aiming to ensure stability and a seamless transition. MongoDB's stock experienced a significant decline, falling between 14% and 25% in premarket trading following the news of Desai's departure and Ittycheria's interim appointment.

As of September 28, 2026, Dev Ittycheria is serving as MongoDB's interim President and CEO while the Board initiates a comprehensive search for a permanent successor, assisted by an executive search firm. Ittycheria also holds positions as a Partner and Senior Advisor at Sequoia Capital (since September 2026) and Lead Independent Director of Datadog. MongoDB has reaffirmed its financial guidance for Q3 and the full fiscal year 2027 and is proceeding with its Investor Day on September 29, 2026, where the leadership team is expected to discuss the company's long-term strategy and focus on AI-driven applications.
