Graphwise’s software is trusted by more than 200 blue-chip customers to improve their enterprise AI capability, making it more accurate, auditable and able to deal with large and diverse data sets. Graphwise does this by structuring enterprise data in a type of database called a knowledge graph, enriching it with context, meaning and connections to form what is known as the "semantic layer." This is increasingly viewed as critical AI infrastructure technology for businesses.

The value of AI depends on the quality and reliability of the data behind it.

Large language models ("LLMs") are strong at processing language, but have limitations, including factual consistency and explaining how they arrived at conclusions. The semantic layer addresses these limitations by giving LLMs a reliable layer of facts to retrieve from and reason over. This is particularly valuable in regulated, data-intensive sectors such as financial services, life sciences and the public sector, where compliance, auditability and data governance are essential.

The company was formed in 2024 through the merger of two pioneers in semantic technologies: Ontotext, founded in Sofia, Bulgaria in 2000 by Atanas Kiryakov, and Vienna-based Semantic Web Company, founded in 2004 by Andreas Blumauer and Martin Kaltenböck.
