monday.com unbundles mondayDB to scale Work OS data faster

monday.com is reworking the engine under its Work OS so boards do not bog down when more teams, automations and AI workflows hit the platform at once. In a May 19 post, the company said mondayDB 3 creates a complete separation of write and read paths, uses a redundant soft-stateful serving layer for read performance, and breaks the coupling between storage and compute.

That matters because mondayDB is not a side project. monday.com describes it as the underlying data architecture for the Work OS platform and ecosystem, built to support a larger scale of boards and dashboards at speed, extend public API and data manipulation capabilities, and open up new use cases and custom workflows. The first mondayDB release landed on June 23, 2023, after work on a replacement began in January 2021 and the new database went into production in July 2023. mondayDB 3 is the next step in that same rewrite, aimed at removing the old tradeoff between flexibility and scale.

For product teams and engineers inside monday.com, the message is clear: the company is trying to move past patching latency problems and toward an architecture that can absorb heavier enterprise traffic without forcing every feature to pay for it. Splitting read and write paths is a classic scaling move, but monday.com’s framing makes it more than an infrastructure cleanup. It is a bet that faster reads, steadier dashboards and less friction on data manipulation will become part of the product itself.

The timing also lines up with a sharper enterprise push. In first quarter 2026, monday.com said revenue reached $351.3 million, up 24% year over year, with record GAAP and non-GAAP operating income and record net adds of customers with more than $500,000 in annual recurring revenue. The company also launched an AI Work Platform with native agents, adding more pressure on the underlying data layer to keep pace.

In its 2025 annual report materials, filed March 13, 2026, monday.com said it had 250,000-plus customers. Secondary reporting on that filing put the company at 3,155 employees and 4,281 customers above $50,000 in ARR at the end of 2025. That is the scale signal in mondayDB 3: not just a cleaner architecture, but evidence that monday.com is building for heavier operational use, where speed, reliability and enterprise depth are now part of the sales pitch as much as the code.
