MariaDB plc
Open-source relational database maker now owned by private equity firm K1.
On the record
Checkpoint: MariaDB 10.6 reaches end of maintenance life, forcing customers to upgrade or migrate away
The call
MariaDB keeps its banking and telecom customers through switching costs, while hyperscalers and AI tools take the growth outside its walls.
MariaDB makes database software that banks and telecom companies use to store and manage data. It is hard to replace because it is built into many companies' operations, which keeps money coming in, but Amazon, Microsoft, and Google offer their own versions that are easier to use and do not require as much staff to manage. The company was bought by a private equity firm and quickly bought other smaller software companies, which usually means the owner wants to extract cash rather than grow bigger; if Microsoft or Google can convince MariaDB's customers to switch to their versions, the company could lose most of its value.
Why
01
AI pressure: AWS, Azure and Google AI-powered database copilots and query tuning assistants. Cloud AI assistants now handle tuning and support tasks that used to require MariaDB expertise or paid help. Could AI do the core job? Only partly.
02
Bigger players: AWS RDS/Aurora, Azure Database for MySQL, Google Cloud SQL, and Oracle's own MySQL. Hyperscalers already run the managed database market MariaDB competes in, and Azure dropped its own MariaDB service in 2025. Could a giant copy it? Yes, easily.
03
What protects it. Banks and telecoms have MariaDB wired into core systems, and ripping it out costs more than staying.
What would change this call
Whether GridGain acquisition (closed March 2026) yields announced new-logo wins by late 2026. Would show AI pivot is winning new customers, not just retaining existing ones.
Customer migration patterns after MariaDB 10.6 end-of-maintenance-life on July 6, 2026. Would reveal whether forced upgrades keep customers on MariaDB or push them to Postgres/hyperscaler alternatives.
Any public revenue disclosure or credible acquisition/exit report involving K1 Investment Management. Would indicate whether K1 is growing the business or preparing a cash-extraction exit.

Questions people ask
- Is MariaDB profitable in 2026?
- MariaDB's financials are opaque under private equity ownership since K1 Investment Management's take-private in September 2024. No audited post-2024 revenue or profit disclosures exist publicly. Pre-takeover, fiscal year 2023 revenue was $53.11M, up 21.58% YoY, but no profitability figures have been confirmed since delisting.
- Who owns MariaDB now?
- K1 Investment Management completed a tender offer in September 2024, acquiring 100% of MariaDB plc shares for approximately $37 million and taking the company private, down sharply from its December 2022 SPAC valuation of about $672 million enterprise value.
- Has MariaDB had layoffs?
- Yes, MariaDB laid off 84 staff, about 28% of its workforce, in October 2023 amid financial restructuring, according to IBTimes on 2023-10-12. Headcount later stabilized, reaching roughly 458 employees by December 2025 per Revelio Labs, up 5.1% year over year.
- Could AI replace MariaDB's database services?
- Generic DBA tuning and support work face erosion from AI copilots and hyperscaler-embedded assistants, but the core database product itself is not directly replaceable. MariaDB responded by launching RAG-in-a-box, native vector search, and MCP server support in its October 2025 Enterprise Platform 2026 release.
- Who is MariaDB's biggest competitor?
- MariaDB faces direct competition from Percona (open-source MySQL/PostgreSQL alternative) and the PostgreSQL ecosystem (EDB, Crunchy Data), plus hyperscaler-managed database services from AWS RDS/Aurora, Azure, and Google Cloud SQL. Microsoft retired its own Azure Database for MariaDB offering by September 2025.
- Is joining MariaDB a safe career move in 2026?
- MariaDB's headcount fell to about 423 employees in early 2024 after 2023 layoffs but recovered to roughly 458 by December 2025 per Revelio Labs, with 78 job postings in 2025, up 57.9% year over year, suggesting cautious rehiring under new K1 ownership since September 2024.
