StarRocks provides an open-source, high-performance data warehouse for real-time analytics, lakehouse queries, and AI agent workloads.

StarRocks is an open-source, high-performance data warehouse designed for real-time analytics. The company was founded by a team of engineers with backgrounds at Baidu and Alibaba, including CEO and co-founder James Sun, who previously worked on the Apache Doris project. StarRocks originated as a fork of Apache Doris in 2020, aiming to address performance limitations in complex query scenarios.

The company's product portfolio centers on a single unified engine that supports real-time ingestion, lakehouse queries, and AI agent workloads, with a focus on sub-second latency for multi-table joins and high-concurrency environments. StarRocks has raised at least $100 million in funding, including a $50 million Series B round led by GGV Capital in 2022, and was valued at over $1 billion in 2025, achieving unicorn status according to TechCrunch. The company is headquartered in Beijing, China, with an additional office in San Mateo, California, and employs approximately 300 people.

StarRocks' customer base includes major internet and technology companies such as Microsoft, Pinterest, Shopee, Tencent, and Didi Chuxing, as well as enterprises like Lenovo and Expedia. The company has not publicly disclosed its revenue, but it operates on a dual model: a free, open-source community edition and a paid enterprise version with additional features like advanced security and technical support. As of mid-2025, StarRocks faces increasing competition from established players like ClickHouse and Apache Druid, as well as newer entrants like Apache Doris itself. The company's reliance on Chinese market customers and its open-core business model present ongoing risks around market concentration and monetization.
