Line Works

What Line Works does

LINE WORKS株式会社 (LINE WORKS Corporation) is a Tokyo-headquartered Japanese enterprise communication and AI productivity platform provider, operating as a subsidiary of LINE Yahoo Corporation (itself under South Korea's NAVER Corporation). Founded in June 2015 as Works Mobile Japan, the company rebranded to LINE WORKS in February 2017 and adopted its current corporate name in January 2024. Its core product is a LINE-UX-based business chat and collaboration suite (messaging, email, calendar, Drive, bulletin board, tasks, contacts) sold on tiered per-user subscriptions (Standard, Premium, Premium Plus), augmented by a growing family of AI add-ons: AiNote (meeting transcription with proprietary Japanese speech recognition at 90.8% character accuracy), AiCall (AI voicebot processing 2.5M calls/month at 80% completion), PaperOn (AI-OCR document processing), Vision (cloud AI camera), AiStudio (RAG-based generative AI from 950 yen/user/month), and Roger (voice AI transceiver for field workers). The platform serves over 5 million users across Japanese enterprises and SMBs in sectors including construction, manufacturing, retail, government, and education, with a distribution model heavily weighted toward channel partners — notably SB C&S (SoftBank), Daiwa Boe, KDDI, and Otsuka Shokai — alongside certified SIER implementation partners.

Underlying the product suite is a cloud-based architecture built on LINE's proven consumer messaging infrastructure, adapted for enterprise security (ISO 27001, SOC 2) with a unified LINE WORKS Platform layer (launched November 2024) providing single-account, centralized administration, and inter-product integration across the family. Revenue mechanics rest on recurring per-user subscriptions, premium add-ons, and volume enterprise licensing, while AI capabilities blend proprietary in-house models (Japanese speech recognition, speaker diarization, AI-OCR) with selectively deployed third-party APIs (OpenAI GPT-4o mini for summarization, Google Gemini API for OCR). Go-to-market is enterprise field sales augmented by a deep partner channel, with the LINE consumer brand providing unique market entry leverage in Japan as the only business chat offering native external LINE integration.
