Management raised its fiscal 2027 revenue forecast to $2.99 billion to $3.03 billion. Historical data shows MongoDB has experienced seven drops of 30% or more within 30 trading days since 2017.

MongoDB launches Atlas Agent Engine, Atlas Infinite and MongoDB 9.0 at Investor Day. MongoDB (MDB) launched several new or updated products with a focus on agentic AI, enterprise modernization and faster data delivery times during its Investor Day presentation on Tuesday. The database company released MongoDB 9.0 for general availability today. They also revealed Atlas Infinite, which MongoDB said is its most significant architectural innovation to Atlas in a decade. It is available for public preview. "The growing use of AI agents is causing applications to use and store more data," said MongoDB Chief Products Officer Ben Cefalo. "MongoDB 9.0 hardens the foundation that more than 70,000 customers already trust with extreme performance, making it significantly faster at scale for mission-critical transactional workloads and AI-powered applications. Meanwhile, Atlas Infinite delivers the elasticity, responsiveness, and accuracy that agentic workloads demand, so enterprises never have to stretch legacy architecture to keep up." MongoDB 9.0 delivers up to 35% faster find-one queries, 30% faster update-one queries, two times the throughput on large instances and 20% higher throughput for transactional workloads compared to 8.0, the company said. MongoDB revealed the Atlas Agent Engine was well. This product unifies governance, memory, and retrieval, ending the choice between a stitched-together stack and being locked into one vendor's model and cloud. "Organizations that want to put agents in production are being forced into a false tradeoff: either adopt one vendor's runtime and accept being locked into a model and cloud, or piece together a framework and manage governance and memory on their own," said Pablo Stern-Plaza, Chief Product Officer of AI and Emerging Products at MongoDB. "With the launch of Atlas Agent Engine, that false tradeoff ends today. Enterprises get the real-time context their agents need, with governance and security built in from the start, and the freedom to run any model, any framework, and on any cloud." Finally, MongoDB announced a new partnership with Cognition to help enterprises modernize for AI workloads. Cognition is the creator of Devin, an autonomous AI software engineer. "Even the most ambitious engineering teams spend much of their capacity keeping legacy systems alive," said Cognition co-founder and CEO Scott Wu. "Devin for MongoDB Modernizations solves that pain. Devin does the heavy lifting, rewriting code across the codebase, so customers reach production on MongoDB in weeks instead of years. Engineers can get back to building great software and solving hard problems." MongoDB shares were down 2% by noon trading on Tuesday. MongoDB cratered 18% on Monday after announcing that CEO CJ Desai was leaving, effective immediately, to lead Meta Platforms' (META) new enterprise segment.
