Our story begins with an open-source software called Apache Pinot — developed by our founders within the gates of LinkedIn. Pinot quickly proved its outstanding capabilities for real-time analytics at scale and, before long, was a household name in the space. Securing $47 million in Series B funding, we expanded our team to over 100 talented individuals worldwide. This pivotal moment empowered us to accelerate product development and enhance our market presence, laying strong foundations for future success. Handling 1 billion queries per week, StarTree outpaced industry giants like Snowflake, delivering unparalleled real-time analytics at a fraction of the cost. Our robust platform and customer-centric approach fueled this incredible milestone, showcasing our industry leadership. With a successful sales kickoff, we embraced our “Lift Off” theme, setting ambitious goals for the year ahead. Unified by a shared vision, we’re ready to pioneer innovation in real-time data, strengthen the community, and drive unparalleled success in 2024 and beyond. We’re assembling a global team of rockstars who are committed to giving every decision-maker the insights they need to make great choices. Sound up your street? We’d love to hear from you. Overview Walmart’s last-mile delivery lifecycle is highly complex, involving 20 to 30+ microservices. Because each microservice maintains its own state of a given entity (such as a customer’s order), tracking the complete life cycle of an order as it moves … For over three years, Slack has utilized Apache Pinot to power customer-facing dashboards and analytics. Historically, these analytics relied on batch processing, where data flowed through Spark into S3 and was ingested into Pinot offline servers. This batch-based approach resulted … As large language models (LLMs) become core infrastructure, a new engineering challenge is taking shape: capturing how these models are used—and how they behave—as it happens. It’s no longer sufficient to count API calls or log failures after the fact. … StarTree extends Apache Pinot into a managed data platform with enterprise-grade features so you can focus on insights, not infrastructure. StarTree Cloud offers public SaaS (Software as a Service) and private BYOC/BYOK deployment options. For more information about our public or private SaaS offering, schedule a demo with our StarTree solutions architect team. Get started quickly with the fully managed, StarTree Cloud service.
