StreamNative (Beijing Yuanliu Data Technology Co., Ltd., referred to as StreamNative), founded in early 2019, is an open-source infrastructure software company built by core developers of Apache Software Foundation top-level projects Apache Pulsar™ and Apache BookKeeper™. The company is developing next-generation streaming data platforms around Apache Pulsar and Apache BookKeeper, and is currently the only startup in the world founded by the original core developers of the Pulsar and BookKeeper projects.
Messaging systems serve as critical infrastructure components for big data platforms, essential for building big data applications. Pulsar adopts a tiered architecture with compute-storage separation, supporting multi-tenancy, persistent storage, and cross-region data replication across multiple data centers. With strong consistency, high throughput, and low-latency scalable streaming data storage capabilities, it elegantly solves technical bottlenecks encountered by popular messaging systems like Kafka in numerous scenarios, while significantly reducing IT infrastructure investment, simplifying operations, and improving stability to accelerate business growth. Developers can migrate from other systems to the Pulsar platform quickly using open-source components developed by StreamNative and its partners without modifying any code.
Numerous large internet companies and traditional enterprises at home and abroad have already adopted Pulsar, with use cases spanning artificial intelligence, finance, telecommunications, live streaming and short video, IoT, retail and e-commerce, online education, and other industries — including US cable giant Comcast, Yahoo!, Tencent, China Telecom Group Co., Ltd., China Mobile, BIGO, and VIPKID.
As a global open-source project, Pulsar currently has nearly 300 contributors worldwide, with its latest version at 2.6.0. Thanks to its rapidly growing active community and increasingly large contributor and developer base, Pulsar can achieve significant feature improvements and version iterations in just a few weeks — which is crucial for the growth of an open-source project.

Sijie Guo, founder and CEO of StreamNative, said: "We see cloud-native as an important technology evolution that is already underway. In the cloud-native era, developers should focus more on applications and microservices rather than wasting time maintaining complex messaging and streaming data infrastructure. As a next-generation cloud-native distributed messaging and streaming platform, Pulsar integrates messaging, storage, and lightweight functional computing, with built-in features that other systems only offer in commercial versions. It is the best solution for real-time messaging and streaming data transmission, storage, and computing in the cloud-native era."
Chen Runze of Source Code Capital, who serves as a StreamNative board member and led this round, said: "As digital infrastructure becomes ubiquitous, massive numbers of objects, processes, and businesses are being brought online. The ingestion, storage, and computing of streaming data will become a common enterprise need, and the importance of streaming data platforms as foundational software continues to grow. Against the backdrop of accelerating enterprise cloud migration, future infrastructure software will inevitably be open-source and cloud-native. StreamNative's product architecture and roadmap align well with these trends. The team has mature community operations experience and has long been committed to cutting-edge technology and product innovation. We believe the team can play an important role in future enterprise digital transformation."
Currently, engineers make up over 80% of StreamNative's team. Founding team members previously worked at well-known companies including Yahoo, Twitter, and EMC. This round of funding will accelerate StreamNative's progress in product R&D, open-source community building, and ecosystem development. StreamNative will also launch cloud-based products built on Apache Pulsar in the coming months.
