Atlas, the company’s cloud-based platform, remained the primary growth engine, contributing 72% of total revenue with 29% growth and surpassing a $2 billion run rate, supported by robust customer expansion and a net ARR expansion rate of 121%, indicating strong workload growth among existing clients.
Customer metrics remained healthy, with total customers rising nearly 20% and large enterprise adoption accelerating, highlighted by major deals including a ~$90 million Atlas agreement and the largest enterprise contract in company history, exceeding $100 million, signaling increasing standardization across hybrid and AI workloads.
Strategically, MongoDB is positioning itself at the center of AI-driven application development through its integrated platform, combining operational databases with vector search and embedding capabilities, which reduces reliance on external tools and supports emerging agentic architectures. While AI adoption is growing rapidly, monetization remains in early stages as most enterprise deployments are experimental rather than fully scaled.
Despite strong execution, some headwinds persist, including revenue mix volatility from bundled deals, limited visibility inherent in its consumption-based model, and variability in enterprise contract timing. Looking ahead, management guided to sustained double-digit growth with continued margin expansion, underpinned by Atlas growth above 20%, disciplined cost management, and ongoing investment in AI innovation, positioning the company for durable long-term growth.
