What Sparticle does
Sparticle is a Tokyo-based AI company founded in July 2019 by Representative Director Tatsuya Kaneda that builds generative AI products for enterprise knowledge management and customer support automation. The company operates legal entities in Japan, the United States (Delaware), and China, and maintains a workforce of approximately 51-100 employees, with 60 reported as of October 2023.
Its core technology combines GPT-based large language models with a proprietary Retrieval-Augmented Generation (RAG) architecture, enabling enterprises to build AI systems grounded in their internal knowledge bases without external data leakage. The product portfolio centers on the GBase platform: GBase (enterprise AI knowledge agent with cross-search, Deep Research, Projects collaboration, and pre-built agents), GBase Support (multilingual AI chatbot with voice, avatar, and 24/7 automated response capabilities), GBase On-Prem (on-premises deployment for highly confidential environments), and GBase GTM (B2B sales targeting tool). Supporting sub-brands include Felo瞬訳 (real-time business translation with RRT technology) and Felo字幕 (real-time video subtitle translation supporting 15+ languages). The platform supports multimodal inputs across text, image, audio, and video.
Sparticle monetizes through a hybrid SaaS model combining per-seat subscriptions and usage-based token consumption, with tiered pricing (14-day free trial, basic monthly plans, annual business/enterprise contracts) and custom enterprise pricing. Go-to-market combines product-led growth (self-serve trial signup with ~3-minute knowledge base setup), enterprise field sales, a channel partner program for SIers and resellers, and OEM/white-label arrangements where partners embed GBase into their own branded solutions. The customer base spans construction (Shimizu Corporation), commercial real estate (NEWOMAN Takanawa/Luminne), end-of-life consulting (Hacosco Ocean), telecommunications (H.I.S. Mobile), and e-commerce/retail (Kanzaki/Kakunoshin, ACROVE, Cross), reflecting a horizontal multi-vertical approach to AI knowledge management and customer support automation.
