    Kazuya Kawahara



Retrieva provides business automation solutions by leveraging state-of-the-art natural language processing technology.

Retrieva is a company specializing in natural language processing, spun out from Preferred Infrastructure Co., Ltd. in November 2016.

Retrieva develops and provides specialized AI products that use state-of-the-art AI technology to support human work, especially focusing on text analysis and voice recognition services.
Currently, Retrieva offers four types of products:“Predictor”, to categorize text automatically; “Talk Coordinator" to support answering queries for operators; “Voice Visualizer” for operators; and “VoC Analyzer" to support data analysis.

“Talk Coordinator” leverages AI to search inquiry history for presenting the most appropriate answers, helping operators in addressing queries.
“Voice Visualizer” immediately flags calls that require support and summarizes the contents to support operators in their conversation.
"VoC Analyzer" helps to find content that leads to product improvement and customer needs from past inquiries, and provides information that leads to marketing activities and product improvement.



Retrieva’s founders realized the potential applications of NLP, machine learning and deep learning in several enterprise use-cases. The team was formerly part of Preferred Infrastructure, and spun-out to become an independent company. Mr. Kawahara, who was a manager in the Manufacturing Division of Preferred Infrastructure, and Mr. Nishitoba, an alumnus of The University of Tokyo Graduate School of Information Science and Technology, founded the company with four of their colleagues.


Retrieva’s team has domain expertise in the fields of NLP, Machine Learning and Deep Learning. The team is also well-equipped in using these technologies to solve the problems of enterprise customers and making the service user-friendly.
