Vitalist is building VitalOS™, a proprietary operating system designed for branded smartwatches and smart wearables.
In this video interview, Sean Croft (Vitalist) and Semir Haddad (MicroEJ) discuss how VitalOS leverages MicroEJ VEE Wear to help brands create differentiated wearable experiences – without relying on fixed, commoditized platforms – and to grow a sustainable ecosystem of devices and apps that evolves over time.
“VitalOS™ is designed to give brands greater control over their wearable product experience. Many companies, entering the wearable category require alignment with existing platforms. Our collaboration with MicroEJ supports an approach that enables companies like Reebok to develop devices that reflect their design priorities and customer needs.”
Kalvie Legat – CEO, Vitalist.
VitalOS™ solves the power-efficiency crisis in wearables.
Unlike traditional OS architectures that drain batteries in 24 hours, VitalOS decouple application logic from hardware power consumption, allowing for faster, lower-cost development using standard development tools.
VitalOS™ is built on MicroEJ’s proven wearable solution, VEE Wear – part of a platform that already powers more than 400 million connected devices worldwide.

Vitalist, MicroEJ, and Reebok are showcasing the Reebok Kinetic smartwatch powered by VitalOS™ at CES 2026, demonstrating how established brands can enter wearables with experiences that reflect their identity and customer needs.
