K1 Acquires MariaDB, a Leading Database Software Company, and Appoints New CEO

Strategic investment aims to accelerate MariaDB’s mission to deliver innovative, scalable database solutions with new executive leadership to drive the next phase of growth

MANHATTAN BEACH, Calif., MILPITAS, Calif., AND DUBLIN, Ireland – Sept. 10, 2024 – K1 Investment Management, LLC (“K1”), one of the largest investors in small-cap enterprise software companies, today announced the completion of its tender offer to acquire 100 percent of the issued ordinary shares of MariaDB plc (NYSE: MRDB) (“MariaDB”), a leader in enterprise database solutions. This strategic investment positions MariaDB to further expand its presence in the enterprise market and continue delivering innovative, scalable solutions globally.


MariaDB, headquartered in Silicon Valley and Dublin, Ireland, serves nearly 700 active customers across industries including banking, telecommunications, government, healthcare and e-commerce. Notable clients include Deutsche Bank, Nokia, RedHat, Samsung and ServiceNow, alongside major public sector entities including the U.S. Department of Defense, and across multiple Intelligence and Federal Civilian agencies. Known for its innovation, scalability and dependability, MariaDB database products power mission-critical applications through its transactional, analytical and mixed workloads.

“To run our strategic risk platform at Deutsche Bank, we needed a database that was reliable and performant while handling a massive amount of data. That’s why we turned to MariaDB,” said Liang Ma, Director Core Strats at Deutsche Bank. “With MariaDB Enterprise Server, we have a database that delivers the stability we need at a fraction of the cost of proprietary alternatives.”

MariaDB also announced the appointment of Rohit de Souza as CEO. Rohit brings considerable leadership experience from his roles at Actian and Micro Focus, where he led global organizations driving growth and transformation. Paul O’Brien, former CEO of MariaDB, will remain involved with the company as an advisor.

“We are thrilled to welcome MariaDB to the K1 portfolio and to have Rohit leading the company into its next phase of growth,” said Sujit Banerjee, Managing Director of K1 Operations, LLC. “Together, we aim to accelerate product innovation and continue MariaDB’s mission of delivering high-quality, enterprise-grade solutions to meet the growing demands of the market.”

MariaDB continues to innovate with upcoming product releases, including the launch of vector search in MariaDB Server and a Kubernetes (K8s) Operator, catering to AI and cloud-native trends. These advancements enable enterprises to build AI-driven applications and deploy scalable solutions, including advanced recommendations, image-based search and intuitive chat bots that leverage large language models (LLMs) and data analysis tools, all while seeking to ensure data reliability at enterprise scale. 

“With K1’s support, we are poised to expand our capabilities and continue delivering the innovative database solutions our customers rely on,” said Rohit de Souza, CEO at MariaDB. “This partnership allows us to further product innovation, advancing our ability to support new workloads driven by AI and the cloud. We remain focused on making it easier for customers to transition from costly alternatives and meet the rapidly growing demands for AI and cloud-based solutions.”

“As we look to the future, with new leadership and the partnership of K1, I have never been more confident in the future of MariaDB. It has been my pleasure to serve MariaDB as CEO and I look forward to supporting Rohit as he transitions into the business,” said Paul O’Brien, former CEO of MariaDB.

MariaDB is the latest transaction announced by K1, following the strategic growth investment in Board Intelligence and the sale of GoCanvas to Nemetschek Group (FRA:NEM). This marks K1’s third take-private transaction following Elmo (ASX: ELO), a leading provider of cloud-based human capital management solutions, and Attraqt (LON: ATQT), a pioneer in AI-driven search and merchandising solutions for online retailers.

Lazard Frères & Co. LLC. served as financial advisor to K1. Kirkland & Ellis LLP, and A&L Goodbody LLP served as legal advisors to K1. Baker Botts LLP and Matheson LLP served as legal advisors to MariaDB.

Certain statements about K1 Investment Management LLC (“K1”) made by portfolio company executives herein are intended to illustrate K1's business relationship with such persons, including with respect to K1's facilities as a business partner, rather than K1's capabilities or expertise with respect to investment advisory services. Portfolio company executives were not compensated in connection with their participation, although they generally receive compensation and investment opportunities in connection with their portfolio company roles, and in certain cases are also owners of portfolio company securities and/or investors in K1-sponsored vehicles. Such compensation and investments subject participants to potential conflicts of interest in making the statements herein. For K1, “carbon neutral” means that any greenhouse gas (GHG) emissions derived from a defined scope of K1’s activities are balanced by an equivalent amount removed, including through our purchase of carbon credits. In this report, our “carbon neutral” status is based on our GHG emissions footprint calculated in accordance with the GHG Protocol as of December 31st, 2023 (comprising Scope 2 Electricity and Gas usage and certain Scope 3 categories: Business Travel and Employee Commuting), amounting to an estimated 3,497 metric tons CO2e. K1 then purchased and applied carbon credits in 2024, amounting to an estimated 6,994 metric tons of CO2e. We engaged a third party to assist with the calculation of K1’s estimated GHG emissions for 2023, but we did not obtain independent, third-party verification of our “carbon neutral” status. To address our 2023 emissions, we contributed to the Conservación y Captura de Carbono / Conservation and Carbon Capture (CO2LTZINGO) reforestation carbon removal project in Coltzingo, Mexico (CAR 1464). This project was certified by the Climate Action Reserve (CAR), using the Protocolo Forestal para México (PFM) Versión 1.5 / Mexico Forest Protocol Version 1.5 and the Guía de Cuantificación de Acervos de Carbono y Monitoreo del Proyecto Versión 1.5 / Project Monitoring and Carbon Stock Quantification Guidance Version 1.5 with a validation date of January 15th, 2019.
