What Cinnamon AI does

Cinnamon AI (株式会社シナモン) is a Japanese enterprise AI company founded in October 2016 by serial entrepreneur Miku Hirano, headquartered in Tokyo with wholly-owned AI research subsidiaries in Hanoi, Ho Chi Minh City, and Taiwan. The company specializes in Intelligent Document Processing (IDP), combining its proprietary Flax Scanner AI-OCR engine with LLM-based Super RAG (Retrieval-Augmented Generation) to extract, structure, and retrieve information from complex, non-standardized documents — including Japanese forms with specialized terminology, tables, handwritten text, and visually rich layouts — without requiring template configuration.

Its product portfolio includes Flax Scanner HUB (a tiered subscription AI-OCR platform with Starter, Basic, and Pro plans plus a 14-day trial and reseller channel), Super RAG (an enterprise RAG product that combines internal documents with large language models), Benefit Payment Assessment AI (an industry-first generative AI solution for medical judgment in life insurance launched April 2026 with Daido Life Insurance), Aurora Clipper (NLP for information extraction), and Rossa Voice (domain-specific voice recognition). The technology stack incorporates a Japanese-adapted LayoutLM achieving 19% higher accuracy than standard Transformers, AURORA few-shot extraction effective with 50-300 training samples, HYCEDIS confidence scoring for AI outputs, and validated by Best Paper Awards at DI@KDD 2021 and ICDAR 2021.

Cinnamon AI generates revenue primarily through multi-tier SaaS subscriptions, enterprise licensing, and professional services, selling predominantly through a direct enterprise field-sales motion targeting C-suites at large Japanese corporations in insurance (Daido Life, Sumitomo Life, NN Life, Sompo Japan, Nippon Life, Tokio Marine, E-design, Hanasaiku), manufacturing (Toyota, Daikin, Mitsubishi Chemical), logistics (Subaru Logistics, Kamigumi), and financial services (Norinchukin Bank, FFG, Fujitsu). Deployments are reported at 150+ companies, with the company holding ISO 27001 and Japanese P-mark privacy certifications. Approximately $51M has been raised to date across multiple rounds from strategic investors including SBI Investment, SPARX Group, Sony Innovation Fund, and major Japanese financial institutions.
