MariaDB Almost Ran Out of Cash. Then It Bought Its Way Back Into the Database Race
The open source MySQL fork reached billions of downloads - and still ended up with $1.8 million in cash. A take-private rescue and three acquisitions later, MariaDB is testing a useful idea: one familiar database can do more jobs, if the company stays disciplined about what enterprises will actually pay for.
RisingWave
RisingWave is a distributed SQL streaming database that lets developers ingest, transform, and serve real-time data using familiar PostgreSQL-compatible SQL instead of specialized stream-processing frameworks. Founded in 2021 by former AWS Redshift engineer Yingjun Wu, the San Francisco company decouples compute from storage in a cloud-native architecture, offers incremental materialized views, and integrates natively with Apache Iceberg to power a streaming lakehouse. Its open-source engine and managed RisingWave Cloud target fraud detection, monitoring, real-time analytics, and increasingly the data infrastructure behind agentic AI.
