Grakn is a database technology that serves as the foundational knowledge base for intelligent systems. It enables these systems to understand complex datasets as a cohesive body of knowledge that can be logically analyzed—an essential cognitive process for humans that has not been feasible for computers until now. Grakn eliminates traditional database limitations and establishes structures that allow for reasoning and inference across large and scalable datasets, which is crucial for the advancement of AI systems and applications. Launched as open-source technology in 2016 after 36 months of computational research, Grakn received the University of Cambridge Computer Lab's "Product of the Year Award" in 2017. Through the open-source community, Grakn is already being utilized in a variety of innovative applications, ranging from simple tax automation bots to complex uses in drug discovery involving protein pathways, networks of drones and robots, cybersecurity, and finance. Its users include notable organizations such as Goldman Sachs, AstraZeneca, Cisco, Deutsche Telekom, AON, and the French Intelligent Services.
