What Fuller does

Fuller (フラー株式会社, ticker 387A) is a Japanese digital partner services firm founded in 2011 by Shuta Shibuya and headquartered with a dual structure in Kashiwa (Chiba) and Niigata. The company delivers end-to-end digital product development — strategy consulting, UX/UI design, app and web engineering, and post-launch data-driven growth optimization — under a 'one team' (ワンチーム) model for Japanese enterprise and mid-market clients across retail, finance, media, consumer goods, government, and gaming. Notable enterprise customers include Nintendo, Mitsubishi Estate, NHK, Kao, Snow Peak, Hard-off, Tokyu Corporation, and Trust Bank.

The company's proprietary technology asset is App Ape (アプリ・エイプ), a mobile app analytics SaaS service that aggregates real-use data from approximately 400,000 Android devices in Japan, serving 500+ corporate clients including app developers, advertising agencies, and financial institutions. App Ape provides competitive benchmarking, user demographic analysis, and market intelligence, and is positioned as the TV-rating equivalent for smartphone apps. The product is complemented by the D-FULLER alliance with Dentsu Group companies (Dentsu Digital, Dentsu, Dentsu Soken) and a strategic co-marketing partnership with Yappli, both of which are also major shareholders following a June 2024 capital event.

Fuller generates revenue through two primary streams: (1) Digital Partner Services, billed as custom-quoted professional services engagements for app/web development, consulting, and design, and (2) App Ape Analytics Platform, a subscription-based SaaS product with monthly billing cadence. Pricing for both streams is not publicly disclosed. The company listed on the Tokyo Stock Exchange Growth Market in July 2025 with ¥50 million in registered capital and approximately 200 employees, marking the first Niigata prefecture listing on TSE Growth Market. Distribution combines direct enterprise sales for partner services with self-serve SaaS onboarding for App Ape via its website.
