HEROZ
HEROZ is a Tokyo-based AI company that builds machine learning systems for games, consumer apps, and enterprise clients. Its engineers developed shogi AI that defeated active professional players, and the company now applies that same deep learning expertise to products and custom projects across finance, construction, entertainment, and other industries.
The company's core technology grew out of brain-game programming, where evaluation functions are learned from large datasets rather than hand-coded by domain experts. That approach, honed through titles like Shogi Wars and world-championship computer shogi software, transfers to business problems that need judgment and decision-making under uncertainty.
HEROZ serves two broad audiences: consumers through mobile games and analytics tools, and organizations through enterprise AI consulting, the HEROZ ASK generative AI platform, and bespoke model development. Its BtoB work spans fraud detection, portfolio analysis, construction planning, and multi-agent systems for major Japanese corporations.
