FoodStock

What FoodStock does

boice Inc. (株式会社ボイス), the operating parent of the FoodStock business, is a Saga, Japan-based technology company founded in July 2011 by Representative Director Nonaka Kazuya. It began as a web production firm and pivoted in 2017 into food freshness preservation by becoming the first DENBA electric field technology dealer in Kyushu; DENBA systems are installed in refrigeration and freezing equipment to extend shelf life and reduce food loss, and are also applied to healthcare/wellness products. In 2022 the company launched an internal FoodStock business, which was spun off in 2024 as FoodStock株式会社, a J-startup Kyushu selected entity that focuses exclusively on food freshness solutions. The company also operates かぶHUNT, a subscription AI-driven stock screening and portfolio organization tool for individual investors, and in 2025 formally launched an AI Development Business delivering custom AI models, NLP solutions, computer vision, and RPA x AI automation services to enterprise clients. All revenue is generated through direct sales via phone, email, and the corporate website contact form, with no public pricing or standard tiers. Banking relationships include Sumitomo Mitsui Banking Corporation, Saga Bank, Saga Kyoei Bank, and GMO Aozora Net Bank. The company remains privately held and founder-controlled with no disclosed external investors, no headcount disclosure, and no reported revenue.
