augment AI was founded by former members of the team that developed Sony’s wena smartwatches after acquiring the wena trademark and patents; Teppei Tsushima leads the company as representative director and CEO. The firm’s first product under the new company, wena X, emphasizes a discreet, two-way snap-on/snap-off design that lets users switch between a classic watch and a smart wristband and claims to be the smallest smartwatch in its category. Technical highlights include a proprietary RTOS-based wena OS optimized for ultra-low power (about one week battery life), a wide curved AMOLED display, SUS316L stainless steel parts with DLC coating, a three-wavelength optical heart-rate sensor with improved accuracy, and support for over 130 activity types. augment AI has a strategic alliance with ACCELStars to develop AI-driven sleep analysis features and states that all user data will be stored and handled on servers located in Japan. The company is launching crowdfunding for wena X on GREEN FUNDING with various early-backer discounts and a 10th Anniversary special mechanical edition limited to 400 units. Its current financial position includes the recently closed ¥170 million seed round (equity and debt) to fund development and mass production.
