MariaDB Corporation, founded in 2009 by Michael 'Monty' Widenius, the original creator of MySQL, is an open-source database company headquartered in Espoo, Finland. The company emerged as a fork of MySQL after its acquisition by Oracle, aiming to maintain the open-source ethos while enhancing database performance and scalability. MariaDB’s flagship product, SkySQL, is a fully managed cloud database service designed to support transactional, analytical, and hybrid workloads.

The company has raised significant funding, including a $25 million round in July 2020 to expand SkySQL, and has attracted notable customers such as DBS Bank, which reported $4.1 million in net savings over five years by migrating to MariaDB. As of 2026, MariaDB continues to focus on cloud-native solutions, integrating technologies like GridGain for in-memory speed. The company claims compatibility with MySQL and Oracle, reducing the need for application rewrites.

MariaDB’s customer base spans industries including finance, telecommunications, and technology, with 75% of Fortune 500 companies reportedly using its products. Despite its growth, MariaDB faces competition from cloud-native database providers like AWS Aurora and Google Cloud SQL, and must navigate the challenges of maintaining open-source credibility while scaling its commercial offerings.
