Performance Analysis

MongoDB’s Q3 results highlight an inflection in its business model, with Atlas, the company’s managed cloud database service, now accounting for 75% of total revenue. Atlas revenue growth accelerated to 30% year over year, driven by both new and expanding workloads among large U.S. and EMEA customers. The platform’s expansion is also evident in the 2,600 net new customers added this quarter, with total customer count surpassing 62,500, up 19% YoY. Notably, self-serve customer additions increased 65% year-to-date, reflecting reduced onboarding friction and enhanced product accessibility.

Operating margin reached 20%, exceeding expectations due to revenue outperformance and delayed investments in engineering and sales capacity, which are expected to ramp in Q4 and FY27.

Free cash flow conversion exceeded 100%, bolstered by strong collections and disciplined expense management. Non-Atlas ARR grew 8%, with multi-year deals providing upside, though management signaled a normalization in multi-year deal impact for FY27.

  • Atlas Growth Outpaces Legacy: Atlas’s share of revenue rose from 68% a year ago to 75%, reinforcing platform-centric strategy.
  • Customer Base Broadens: Both enterprise and self-serve motions contributed to record customer additions, highlighting scalable go-to-market execution.
  • Profitability Leverage: Margin expansion was achieved even as Atlas’s mix increased, reflecting operational discipline and deferred investment timing.

MongoDB’s ability to drive both top-line acceleration and margin expansion, while investing in strategic growth areas, positions it as a durable infrastructure winner amid ongoing cloud and AI shifts.

Executive Commentary

"Atlas performance was strong, accelerating to 30% year-over-year growth, up from 29% in Q2 and 26% in Q1. We generated total revenue of $628 million, up 19% year over year, and about the high end of our guidance driven by strength in Atlas... The expansion opportunity in front of us is immense. We already serve more than 70% of the Fortune 100 and many of the world's largest banks, healthcare organizations, and manufacturers run their mission-critical workloads on MongoDB. Even with this foundation, there is still significant room to broaden our footprint within the enterprise."

CJ Desai, President and CEO

"Atlas revenue outperformed our expectations as year-over-year growth accelerated to 30 percent in the third quarter and now represents 75 percent of total revenue... We are very pleased with our stronger-than-expected operating margin results, which benefited from both our revenue outperformance and lower-than-expected operating expenses. Operating cash flow was well above our expectations at $144 million, and free cash flow was $140 million... We remain confident in our ability to drive higher and more consistent free cash flow going forward."

Strategic Positioning

1. Atlas as the Platform Core

Atlas, MongoDB’s fully managed cloud database, has become the company’s central growth engine, now generating three-quarters of total revenue. This transition reflects a deliberate shift away from legacy licensing toward recurring, consumption-driven revenue. Atlas’s broad adoption in both enterprise and self-serve segments is enabling MongoDB to win net new workloads and expand within existing customers, with particular strength in the U.S. and EMEA regions.

2. AI-Ready Data Infrastructure

MongoDB is positioning itself as the foundational data platform for AI-native and enterprise AI workloads. The company’s document model, vector search, and Voyage AI embeddings address the need for real-time, context-rich data in AI applications. While AI tailwinds have not yet materially impacted results, customer stories highlight MongoDB’s technical differentiation in supporting high-growth AI startups and large enterprises experimenting with advanced AI agents.

3. Dual-Track Go-to-Market Focus

Leadership is doubling down on both Fortune 500 expansion and developer ecosystem engagement—a dual strategy designed to capture large enterprise modernization budgets and grassroots adoption in the AI-native startup community. Initiatives like “Reclaim the Bay” and developer-centric events in San Francisco are aimed at regaining mindshare among West Coast innovators, while CEO CJ Desai’s personal network is being leveraged to accelerate enterprise penetration.

4. Disciplined Capital Allocation and Margin Management

MongoDB is balancing aggressive investment in engineering and sales capacity with tight expense control and share buybacks. The company delayed some planned investments into Q4 and FY27, benefiting operating margins in the near term. Actions such as settling RSU tax obligations in cash and executing on a $1 billion buyback authorization demonstrate a commitment to managing dilution and optimizing capital structure.

5. Product Innovation and M&A Selectivity

Product velocity remains high, with recent releases like Atlas 8.0 and the Voyage AI acquisition enhancing performance and AI capabilities. Leadership reiterated a preference for organic investment, but remains open to targeted M&A that accelerates the roadmap or brings in differentiated talent, as seen with the Voyage AI deal.

Key Considerations

This quarter’s results reinforce MongoDB’s evolution from a niche developer tool to a mission-critical data platform for global enterprises and AI-native disruptors. The company’s ability to scale Atlas, maintain high net ARR expansion, and unlock new AI use cases will be pivotal for sustaining durable growth.

Key Considerations:

  • Atlas Mix Shift: As Atlas grows as a percentage of revenue, investors should monitor gross margin trends and the pace of margin improvement within the segment.
  • AI Adoption Timing: While MongoDB is well positioned for AI workloads, the timing and scale of material revenue impact from AI remains uncertain and is not yet embedded in current results.
  • Go-to-Market Execution: Continued traction in both enterprise and self-serve channels is critical, especially as leadership invests in developer outreach and Fortune 500 relationships.
