HACARUS INC. was founded in Kyoto as an AI startup in 2014. Our strength is the ability to extract features from small amounts of data and the high interpretability of Sparse Modeling technology. We apply Sparse Modeling technology to AI.
The current mainstream technology of AI, Deep Learning, requires a large amount of data for training and has the problem that the decision-making process of AI is a black-box. Another problem is that training on the edge side is difficult because a large amount of computing resources are required in the training phase. We are trying to solve these problems with our unique AI.
Kyoto, where our headquarters is located, is a hub of well-known companies representing manufacturing and life-sciences industries, and has many years of accumulated know-how and experience in these industries. By leveraging this know-how and experience, we are focusing on the development of AI that does not rely solely on data. We listen closely to the opinions of the people in the industries and work on the realization of AI that can coexist with humans.

Chief Health Officer
Hacarus is not only innovating in AI technology – we are also exploring new ways to keep our team healthy and happy.
With our Chief Health Officer, we have put a focus on the well-being of each of our team members. Engineers, who spend many hours every day in front of a computer, are likely to develop back issues from their sitting posture. At the Hacarus office, each team member can take part in exercises several times per week, to avoid such issues.
Machine Learning Community
Our team members are actively engaged in the local and international machine learning community. As part of this engagement, we co-organize the monthly machine learning meetup in Kansai.
We also release some of our software projects as Open Source on GitHub. This way we strengthen our dialog and knowledge exchange with the AI tech community.
