Business Model
What each company does and how it makes money
MongoDB is a modern database platform company that offers a flexible, document-based database system as an alternative to traditional relational databases. It generates revenue primarily through its cloud-based MongoDB Atlas service — which accounts for over 60% of total revenue — along with its on-premise Enterprise Advanced licenses and professional services. The company's key advantage is its developer-friendly document model that enables faster application development and its first-mover position in the NoSQL database market.
Samsara is a technology company that provides an IoT platform connecting physical operations data to its Connected Operations Cloud. It generates revenue primarily through subscription fees for its cloud platform — which includes video-based safety, vehicle telematics, equipment monitoring, and site visibility applications — with over 90% of revenue coming from subscriptions. The company's competitive advantage lies in its integrated hardware-software ecosystem that creates high switching costs and network effects as customers deploy more devices across their operations.
