Yugabyte is an open-source distributed SQL database that combines strong consistency with ACID transactional support across data centers and regions. It supports two APIs—PostgreSQL-compatible YSQL and Cassandra-compatible YCQL—on the same underlying distributed engine, enabling automatic sharding, replication, and dynamic scaling. The company serves cloud-native enterprises in financial services, payments, streaming, and IoT that need multi-region active-active deployments with predictable performance.

TimescaleDB is an open-source PostgreSQL extension optimized for time-series data, delivering 10-100x faster query performance than MongoDB and InfluxDB while supporting millions of events per second with up to 95% storage compression. Built by Ajay Kulkarni and Michael Freedman (Princeton professor), it serves companies ingesting and analyzing massive volumes of time-stamped data across IoT, blockchain, maritime, and industrial applications. The product maintains full PostgreSQL compatibility—same drivers, clients, and SQL—while adding automatic time-partitioning (hypertables) and columnar compression.

Aiven is a fully managed, open source data platform that handles the operational complexity of streaming, storing, and serving data across AWS, Azure, GCP, and other cloud providers.

Built on open source services like Apache Kafka, PostgreSQL, and OpenSearch, Aiven prevents vendor lock-in while delivering enterprise-grade reliability. It serves businesses from startups to Fortune 500 companies across 60+ countries seeking simplified multi-cloud data infrastructure.
