Semantic Artificial Intelligence since 2000

In a world of Big Data, Leiki is dedicated to make sense of it all. Most companies focus on analysing numbers, but what would you do when your data is text? This is where we come in. Leiki technology can understand text like a human. So instead of the human adapting to the machine, we make the machine adapt to the human.

Based on two decades of continuous R&D efforts and experience, Leiki’s semantic AI technology analyses text with more than 200,000 topics connected to millions of rules, giving an unparalleled understanding of any given text.

With such technology, we offer a wide range of uniquely capable services, from content recommendation and semantic search, to custom audiences for programmatic advertising, to media monitoring and automated self-service customer care.

Founded in Finland in 2000, Leiki today operates in Europe and the United States. We partner with some of the most powerful brands, increasing their ability to reach out to interested customers and understand them accurately and in more detail. In the future, we see an online world centred around the user dominated by relevant content.
