Storyline is commercializing the ZEN Craft Decaf Process, a proprietary supercritical CO2 fluid method that lets roasters fine-tune and selectively remove only caffeine, effectively introducing controllable “caffeine strength” levels without degrading taste. After completing its lab phase in collaboration with Tohoku University, the company has begun shipping prototype-grade beans with stable quality. It also operates CHOOZE COFFEE, a demonstration café in Tokyo’s Nihonbashi district where customers pick their desired caffeine content for every drink, showcasing the technology’s consumer appeal. The newly raised capital will accelerate R&D and system buildup, support the development of high-quality decaf beans, and launch the B2B offering “CHOOZE COFFEE for BIZ.” Storyline intends to partner with domestic and international coffee businesses to normalize the act of “choosing caffeine” as a new value proposition. Financially, the company secured ¥150 million in fresh funds through a mix of equity and loans; no revenue or user figures were disclosed.
