StarTree is a startup that offers a real-time analytics platform, StarTree Cloud, which is powered by the Apache Pinot database. This platform is trusted by industry leaders and is used extensively for user-facing applications. StarTree's primary clients are businesses that require real-time analytics for their operations, such as advertising technology companies and financial institutions.

The company operates in the cloud services market, specifically in the Database-as-a-Service (DBaaS) sector. DBaaS is a cloud-based approach to data storage and management, where the database is maintained, managed, and backed up on a cloud server by a service provider, freeing businesses from the administrative burdens of managing their own databases.

StarTree Cloud is available as a public Software-as-a-Service (SaaS) or a private SaaS, which they call Bring Your Own Cloud (BYOC). This means that clients can choose to have their data hosted on a public cloud, or on their own private cloud. The service is available on major cloud platforms like AWS, Azure Cloud, and Google Cloud.

StarTree's business model revolves around offering its DBaaS on a subscription basis. This means that clients pay a regular fee to use the service, providing the company with a steady stream of revenue. The company also offers a free trial, which can help attract potential customers.

At the core of StarTree Cloud is Apache Pinot, a database built specifically for fast and scalable user-facing, real-time analytics. Apache Pinot uses a unique star-tree index for fast, scalable aggregations. StarTree, named after this specialized index type, was founded by the original creators of Apache Pinot.
