What Machine Learning Solutions does

Machine Learning Solutions Inc. (マシンラーニング・ソリューションズ株式会社) is a Tokyo-based AI consulting firm established in May 2017 as a subsidiary of Transcosmos Corporation (トランスコスモス株式会社), with additional founding investment from Fuji Startup Ventures and teamLab. The company provides machine learning technical support, consulting, and incubation services to enterprise clients, addressing challenges in data cleansing, neural network design, computational resource management, and model performance evaluation. It operates two wholly-owned subsidiaries — Langsmith Inc. (NLP and writing assistance AI) and Edge Intelligence Systems Inc. (WebDNN edge AI framework) — and serves a hybrid customer base spanning large enterprises, educational institutions, and researchers/academics in Japan.

The company's product portfolio spans both enterprise AI deployments and consumer-facing tools. Core offerings include Langsmith Cowriter (an AI writing assistant sold at ¥1,500/month via direct website), the Founder AI avatar system (a multimodal person-replicating AI that generates responses, voice synthesis, and 3D avatar animation in real time from a single photo and lecture transcripts, operating fully on local Mac mini hardware without external AI services, deployed for Transcosmos to preserve its founder's management philosophy), and EILog (AI English learning service deployed at Sankei Human Learning for secondary school English writing). Underlying technology includes WebDNN (browser-based deep neural network execution framework originating from Tokyo University Harada/Ushiku Lab), TEASPN (a writing assistance protocol co-developed with RIKEN AIP), and open-source LLMs fine-tuned via the STEP (Staged Parameter-Efficient Pre-training) methodology.

MLS generates revenue through three streams: (1) professional services AI consulting and technical support for enterprise clients including project planning, ML model development, service integration, and performance optimization; (2) incubation equity investment returns from portfolio ML startups; and (3) subscription revenue from Langsmith Cowriter (¥1,500/month, the only publicly disclosed price point). The company employs 1-10 staff, operates from a single Tokyo headquarters in Toshima-ku, distributes services exclusively through domestic direct enterprise sales, public seminars, and academic publication channels, and has not disclosed revenue, funding totals, or international expansion plans.
