- Marsdy
Participated · Series A · Aug 2026
Marsdy offers AutoDate, a DX solution that integrates the latest LLMs and generative AI with human-in-the-loop tuning and quality assurance to automate complex, non-standard tasks. The product emphasizes a hybrid approach—AI for automation plus human correction and operational support—to achieve higher accuracy and real-world reliability. Marsdy positions AutoDate to extend automation into areas previously considered infeasible for AI alone, such as handwritten form digitization. The company says adoption is expanding and that key operating focus areas include AI-agent research and strengthening its product development and DX-specialist teams. Headquartered in Minato-ku, Tokyo, Marsdy is led by CEO 武藤大揮 and is entering an organizational growth phase, actively recruiting across engineering, sales, and leadership roles. Following its Series A close, Marsdy plans to invest the new capital in R&D, development capacity, team expansion, and marketing to accelerate business growth.
- IVRy
Participated · Series D · Nov 2025
Founded in 2019, IVRy offers the cloud-based voice AI service “IVRy (アイブリー),” which automates 24/7 telephone reception, analyzes call data, and emphasizes “hallucination-zero” dialogue accuracy. The service is deployed across Japan’s 47 prefectures and more than 97 industries, supporting over 40,000 customer accounts and growing at a pace surpassing the T2D3 benchmark. Leveraging recent advances in large language models, the company is expanding beyond call automation to launch “IVRy Data Hub,” a platform that converts unstructured communication data—calls, emails, and chats—into actionable business insights. Future plans include deeper penetration of the enterprise segment, strengthening global-level AI development, and pursuing M&A for non-linear growth. Proceeds from the latest financing will fund hiring in enterprise sales, enhanced AI product R&D, and the build-out of a robust operating base. To date, IVRy has raised a cumulative ¥10.61 billion, underscoring investor confidence in its mission to deliver cutting-edge technology to every person and company.
