Why voize? Because we're more than just a job!

At voize, we believe the greatest gift to frontline workers is time - time to care, connect, and be present. Today, that time is lost to busywork and complex systems that pull them away from what matters most: people.

Our vision is to change that by building AI companions that seamlessly take over digital workflows. We don't replace humans with technology - we amplify their impact.

voize is backed by Ycombinator and Europe's leading VCs, already installed in over 1.000 senior care homes and trusted by more than 75.000 users. With our self-developed voize AI, we're transforming the healthcare industry and creating value in other sectors too.
