§Winston Score History

The full picture

MongoDB makes software that helps companies store and manage large amounts of data. Instead of organizing data in traditional rows and columns like a spreadsheet, MongoDB uses a flexible format that makes it easier to build modern apps. Its main product is a database platform used by software developers at companies ranging from small startups to large enterprises like Toyota and Barclays.

MongoDB earns most of its revenue through subscriptions to its cloud-based service, called Atlas, which lets customers run databases without managing their own servers. The company operates globally, with customers in over 100 countries, and generates roughly $2 billion in annual revenue. Its competitive moat comes from developer loyalty — once engineers learn and build on MongoDB, switching to a different database is costly and time-consuming. The main risk is intense competition from cloud giants like Amazon, Google, and Microsoft, all of which offer their own competing database services and can bundle them cheaply with other cloud products.

Revenue accelerating

MongoDB grew revenue 30% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
