As noted in the European Union’s list of significant company acquisitions, Apple has acquired graph database maker Kuzu, Inc. The EU classifies an acquisition as “significant” not based on the company’s size, but on whether it involves providing core platform services.

Kuzu was founded in Ontario in 2023 and had approximately ten employees at the time of the acquisition. The company’s website has since been taken offline, and its GitHub software repository was archived on October 10, 2025.

William Gallagher for AppleInsider:

According to the company’s LinkedIn profile, Kuzu was “an embedded graph database built for query speed, scalability, and easy of use.”

A graph database differs from the more common relational database, such as that used by FileMaker.

With a relational database, data is held in connected tables that are set up at the start. These databases are analogous to office filing cabinets with different drawers for different types of information.

So in a relational database, looking up someone in a table of customers can link you to a table of their previous orders. Then with another table you can see who else has ordered the same items.

In comparison, a graph database is more like a mind map. With a graph database, the customer is connected to their orders, and also to any other customers.

Both approaches have their benefits, and the ones for the graph database is that it can be faster…

Based on the Github archive data and also a Twitter post from an ex-Kuzu engineer, Apple appears to have acquired the company in October 2025.
