MongoDB CEO Dev Ittycheria has resigned effective immediately to lead Meta's enterprise platform, causing the company's stock to drop 20% in after-hours trading.

The sudden departure was announced on September 28, 2026, with Meta confirming Ittycheria will oversee its enterprise-focused initiatives. MongoDB's board has appointed CFO Michael Gordon as interim CEO while a permanent successor is sought.

Analysts expressed concerns about leadership continuity and MongoDB's growth strategy, especially amid increasing competition in the database market. The stock decline reflects investor uncertainty about the company's near-term direction.

Ittycheria, who led MongoDB since 2014, is credited with scaling the company through its IPO and cloud transition. Meta's move signals its push into enterprise services, leveraging Ittycheria's experience in developer platforms.
