About
Consulting and product development.
Kiyari G.K. (合同会社きやり) is a Japanese limited liability company headquartered in Tokyo. We help clients plan, build and run software, and we build and operate products of our own with the same team and the same standards.
Our products start with problems we had ourselves. AI Broker began after years of trying to invest well with the tools available to retail investors, and became a platform that publishes daily momentum rankings with every backtest reproducible. We hold every product to the same rule: data, not hype.
- Technical consultingArchitecture reviews, technology choices and delivery plans, grounded in systems we run ourselves.
- Product developmentFrom first prototype to launched web app, with design, engineering, hosting and support under one roof.
- Data and quantitative systemsData pipelines, analytics and research platforms built to be accurate and reproducible, as in AI Broker.
- Applied AILanguage models, voice and image recognition put to practical use, as in Yuki and Cellar Book.
