Voize
View Company Profilevoize (operating via voize.ai) is a premier healthcare technology enterprise engineered to build the ultimate AI companion for nurses and caregivers. Founded in 2020 and headquartered in Germany, the company fundamentally disrupts traditional, time-consuming medical charting by natively unifying advanced ambient speech recognition with seamless Electronic Health Record (EHR) synchronization. Moving far beyond generic dictation software, voize is purpose-built for skilled nursing and elder care, automatically categorizing spoken notes into structured data fields, recognizing resident names, and functioning fully offline during network outages. The platform empowers frontline workers to document directly at the point of care, eliminating end-of-shift charting and drastically reducing administrative burden. Under the hood, their technology core leverages specialized natural language processing trained exclusively on clinical terminology and nursing workflows, alongside robust grammar correction and real-time integration via the voize Gateway. Capturing massive market trust with over 1,500 care facilities and tens of thousands of nurses relying on the platform, and backed by a recent $50 million Series A funding round led by Balderton Capital, voize remains a definitive cornerstone of the modern HealthTech landscape, returning critical time to frontline workers so they can focus on what matters most: human connection and patient care.
