Vitalist Inc.

VitalOS™ Platform Capabilities

VitalOS™ is built on MicroEJ’s proven virtualization technology, MicroEJ VEE, and its wearable solution, VEE Wear — part of a platform that already powers more than 400 million connected devices worldwide. Together, the companies have created a foundation that streamlines the cost, speed, and scale of wearable development:

• Low-power architecture designed to support extended battery performance
• 6–9 month development cycles
• Customization options for brand-specific experiences
• Hardware-agnostic scalability

“We designed VitalOS™ to be future-proof from day one. Whether it’s watches today or new form factors tomorrow, brands can scale their experiences seamlessly across generations. The platform is intended to support extended product lifecycles and efficient software-update processes.”

said Sean Croft, Chief Product Officer at Vitalist.

“VEE Wear brings to VitalOS™ the same proven foundation that already powers millions of embedded and IoT devices worldwide. By combining ultra-low power efficiency, reliability, and scalability, VEE Wear enables VitalOS™ to support wearables designed for efficient power consumption and scalability across device generations. Our collaboration with Vitalist provides brands with an additional option when developing connected devices.”

added Dr. Fred Rivard, CEO of MicroEJ.
