Octanove Labs

What Octanove Labs does

Octanove Labs is an independent, for-profit AI research lab structured as a single-member LLC and operated by founder Masato Hagiwara. The company specializes in natural language processing and machine learning for Asian languages, with particular depth in Chinese, Japanese, and Korean, and a vertical focus on education applications including language learning, writing assistance, and automated essay scoring. Its portfolio combines research outputs with professional services: an Ultra Fine-Grained Named Entity Recognition system that ranked #2 at TAC KBP 2019, the TEASPN framework for integrated writing assistance, the Open Language Profiles platform for sharing educational linguistic resources, the Github Typo Corpus multilingual misspelling dataset, contributions to the AllenNLP course, and a Manning Publications book on real-world NLP. The lab also publishes a weekly Japanese-language newsletter, State of AI Guides.

The company operates a sales-led, professional services model, delivering research, development, and consulting for NLP and ML on a contract basis. Engagements are sourced through direct inbound (email to the founder) and likely through the founder's professional network, with no public pricing, marketplace listings, or intermediary channels. The customer base spans education technology (EduLab, ACTNext, Lang-8), research institutions (Allen Institute for Artificial Intelligence, RIKEN AIP), and technology firms (appArray, Autify, MiraiTranslate, Studio Ousia). There is no disclosed funding, no parent company, and no evidence of a productized SaaS offering; all revenue appears to flow from project-based consulting, sponsored research, and content-driven thought leadership.
