MongoDB, Inc. vs Redis, Inc.: Strategic Comparison

This in-depth comparison examines MongoDB, Inc. and Redis, Inc. across revenue, market value, business model, competitive positioning, and long-term growth strategy. Whether you are researching MongoDB, Inc. on its own, evaluating Redis, Inc., or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between MongoDB, Inc. and Redis, Inc. is widest.

On the headline numbers, annual revenue is $2.5B (FY2026) for MongoDB, Inc. and N/A for Redis, Inc., while their respective market capitalizations stand at $30.1B and N/A. Both MongoDB, Inc. and Redis, Inc. are headquartered in United States. Their local markets and applicable rules may still differ.

MongoDB, Inc.: MongoDB, Inc. is a New York-based database software company best known for MongoDB, a document database that stores data as flexible JSON-like (BSON) documents instead of rows and columns. Its managed service, MongoDB Atlas, runs on AWS, Google Cloud, and Microsoft Azure and accounts for most revenue. The company had 5,636 employees at January 31, 2026 and more than 70,600 customers at July 31, 2026. The company is headquartered in New York City, New York. The database revolution pioneer was founded in 2007 in New York City by Dwight Merriman, Eliot Horowitz, and Kevin Ryan under the name 10gen, fundamentally transforming data architectures by replacing rigid relational tables with flexible JSON-like documents.

Redis, Inc.: Redis is a real-time data platform best known as the cache that sits in front of slower databases. Because data lives in RAM, reads and writes typically complete in under a millisecond, which is why Redis is used for session storage, leaderboards, rate limiting, queues and, more recently, vector search for AI applications. The company is headquartered in San Francisco, California. Redis was founded in 2011 in Tel Aviv, Israel, by Ofer Bengal and Yiftach Shoolman as Garantia Data (later Redis Labs), commercializing the legendary in-memory open-source data structure store created by Salvatore Sanfilippo into a global real-time data platform.

MongoDB, Inc. and Redis, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between MongoDB, Inc. and Redis, Inc..

MongoDB, Inc. business model: MongoDB runs a developer-led, open-core model. The free Community Server (source-available under the SSPL since 2018) drives adoption. Revenue comes from MongoDB Atlas, a fully managed service on AWS, Google Cloud, and Microsoft Azure billed on consumption of compute, storage, and data transfer; from MongoDB Enterprise Advanced, a self-managed subscription with security, management tooling, and support; and from services. Subscription revenue was about 97% of total revenue in fiscal 2026. In Q2 fiscal 2027, Atlas generated $565.9M (up 29%) and Enterprise Advanced and other subscription revenue $181.2M (up 36%).

Redis, Inc. business model: Redis follows an open-core model. The Redis engine is free to download, while the company charges for Redis Cloud, a managed database service billed by memory, throughput and features on AWS, Google Cloud and Azure, and for Redis Software, a self-managed subscription for on-premises and private-cloud deployments. Paid tiers add Active-Active geo-replication, high availability, Redis Flex (RAM plus SSD storage), security controls and enterprise support. AI products such as vector search, LangCache and Redis Feature Form are sold on top of the same platform.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of MongoDB, Inc. stack up against those of Redis, Inc..

MongoDB, Inc. competitive advantage: MongoDB's advantage rests on developer familiarity with the document model, the ability to run the same database self-managed or on any of the three largest clouds, integrated search and vector search inside Atlas, and high switching costs once applications are built on it. Its customer base grew from about 54,500 in January 2025 to more than 70,600 in July 2026.

Redis, Inc. competitive advantage: Redis's advantages are developer familiarity built over 15+ years, sub-millisecond in-memory performance, a broad set of data structures in one engine (strings, hashes, streams, JSON, search, vectors), and paid features the community edition lacks, such as Active-Active replication based on CRDTs and Redis Flex tiering. Its January 2026 customer base of 12,000+ paying accounts, including roughly a third of the Fortune 100, gives it a large installed base for upselling AI features.

Future prospects matter as much as current results. The growth strategies below explain how MongoDB, Inc. and Redis, Inc. each plan to expand from here.

MongoDB, Inc. growth strategy: Under CEO CJ Desai, MongoDB is positioning itself as a data platform for AI applications: Atlas Vector Search, Voyage AI embedding and reranking models (acquired in 2025), and tooling that connects coding agents to operational data. It also pursues migrations off relational databases and sells a 'run anywhere' approach spanning self-managed Enterprise Advanced and multi-cloud Atlas.

Redis, Inc. growth strategy: Growth rests on moving customers from free Redis to Redis Cloud, expanding large accounts (50+ spend over $1M a year), and selling AI features such as vector search, semantic caching and feature stores. Cloud marketplace listings on AWS, Google Cloud and Azure let enterprises buy Redis against existing cloud commitments.

A closer look at the financial trajectory of MongoDB, Inc. and Redis, Inc. rounds out the comparison.

MongoDB, Inc.: MongoDB grew revenue from $114.8M in fiscal 2017 to $2.464B in fiscal 2026 while narrowing GAAP losses from a peak of $345.4M in fiscal 2023 to $71.2M in fiscal 2026.
