Kardi Ai, a Czech healthtech startup, has secured €5.3 million in a Series A funding round. The company provides a system for long-term heart rhythm monitoring, which integrates an ECG-enabled chest strap, a mobile application, and AI-powered analysis software.
The technology aims to detect intermittent arrhythmias that traditional 24-hour Holter monitors often miss. Internal data from over 6,700 users indicates that the platform identifies cardiac arrhythmias in approximately 37% of monitored individuals.
The company has obtained EU MDR Class IIa certification for its medical device. Following its success in Europe, Kardi Ai is expanding into India and the UAE, targeting a combined market of approximately two billion people.
Kardi Ai was named Best AI-Enabled Startup at the Central European Startup Awards 2025 and Best HealthTech Startup at the Global Startup Awards 2026. The company plans to scale its operations through partnerships with hospitals, cardiologists, and insurance providers.
