I listened carefully to Yann Fleureau's speech during the DATADRIVENPARIS event about his 4 past years as a Co-Founder and CEO of CardioLogs and his journey towards building and selling an AI-based Clinical Decision Support System (CDSS) for Clinicians in the Cardiology space. CardioLogs is a Paris-based Startup building Deep-Learning Algorithms for ECG (EKG) analysis. They have raised approximately 10M$ to date and have won approval for commercialization in Europe of the first medical grade deep-learning technology in 2016 and the second in the US in 2017. Yann is a graduate from the prestigious Polytechnic School of Paris (X) and passionate about New Technology & Medicine (https://cardiologs.com/). The last 4 years of CardioLogs illustrate well the challenges of implementing an AI-based solution in clinical practice.
