About Us

The Company

Akai Kaeru is a company with deep roots in visual data analytics research. Its two co-founders combine decades of research expertise in interactive high-dimensional data visualization. They started out long before the terms big data, data science, and explainable AI became the ubiquitous buzzwords they are now. Akai Kaeru was founded in 2016 to evolve these acclaimed research products into practical software to help data scientists solve stubborn problems in real-world applications. This is and has been our guiding mantra.
