At Starburst, we are working to dismantle the status quo of data silos and vendor lock-in every single day. Starburst offers a full-featured data lake analytics platform, built on open-source Trino. Our platform includes all the capabilities needed to discover, organize, and consume data without the need for time-consuming and costly migration projects. Today more than 200 leading organizations trust us to make better decisions faster. Though Starburst has raised $414M in venture funding from top investors, we were founded in a rather unusual way as we bootstrapped the business with customers and revenue from the very beginning! We are a remote-first company with employees all over the world and are proud to be named a Best Place to Work. Our founders are the creators of Trino (and previously Presto at Facebook). 10 years ago, they created Trino as the analytic database to stand the test of time. Funny enough, they never had any intentions to start a company around it. 5 years ago, we started Starburst with a similarly audacious goal: To build an iconic company that would stand the test of time. We are solving exceptionally complex and meaningful challenges here and as we innovate, we each have the opportunity to build our careers alongside Starbursts’s growth. Starburst has raised $414 million in venture funding and we are hiring across all functions to support our massive growth!
