CEO Message

HACARUS was founded in 2014 as an AI venture under the mission of “Leveraging Technology to Enhance People’s Health.” Originally, we used AI technology (artificial intelligence) as a means of optimizing personal diets and nutrients.

However In 2016, we came to think our technology, which had been specialized in the healthcare field, could be applied to solve problems in the industrial and medical fields as well. We pivoted our business and are now looking to take on the world. Despite the change in direction, our core mission still stays true today.

— Kenshin Fujiwara, Hacarus CEO
