Idoven
AI-powered platform for rapid, accurate electrocardiogram analysis
About Idoven
Idoven is a health technology company focused on preventing cardiovascular disease through early detection and precision medicine. The company was founded in Madrid in 2018 by cardiologist Dr. Manuel Marina Breysse, serial entrepreneur Iñigo Juantegui, and machine learning scientist José María Lillo Castellano. The founding was the culmination of nearly a decade of research in cardiology and machine learning at Spain's National Center for Cardiovascular Research (CNIC). Dr. Marina's background as a sports cardiologist for elite Spanish athletes and his research in cardiac arrhythmias, combined with Lillo Castellano's expertise in machine learning and data analytics, formed the company's scientific foundation. Juantegui brought extensive entrepreneurial experience, having previously co-founded and sold the successful food delivery startup La Nevera Roja.
Read full description
Idoven's core offering is Willem™, a cloud-based, AI-powered software platform that analyzes electrocardiograms (ECGs) to detect cardiac diseases. Certified as an EU MDR Medical Device Class IIa, the platform is designed to provide rapid and accurate ECG interpretation, augmenting the capabilities of clinicians. It can identify over 80 cardiac patterns, which constitute 90% of the most common heart issues, with cardiologist-level accuracy. A key feature of the Willem™ platform is its device-agnostic nature, allowing it to integrate with any ECG hardware—from 12-lead hospital machines to consumer wearables—and existing electronic health record (EHR) systems via APIs. This approach has enabled Idoven to build one of the world's largest and most diverse ECG databases for training its deep learning models.
The company operates on a B2B Software-as-a-Service (SaaS) model, partnering with medical device manufacturers, pharmaceutical companies, and clinical stakeholders. These partnerships focus on integrating Idoven's AI for faster diagnostics, patient risk stratification, and monitoring cardiac safety in drug trials. Idoven has secured significant funding from investors including Insight Partners, Northzone, and Wayra (Telefónica), as well as grants from the European Innovation Council (EIC). Notable angel investors include former Real Madrid goalkeeper Iker Casillas, who became an ambassador for the company after his own heart attack in 2019.
