Chronolife

What Chronolife does

Chronolife is a Paris-based digital health and medtech company founded in 2015 and incubated by healthtech investor iBionext (majority shareholder). The company develops multiparametric smart textile wearables and operates an open digital health platform for continuous, real-life remote patient monitoring and predictive health analytics. Its core products are the CE Class IIa-certified Keesense connected t-shirt (for cardiac rehabilitation and chronic disease monitoring), the Smart Textile t-shirt (for sports recovery), and the Reference Design service for custom wearable development targeting occupational health use cases. Sensors are integrated directly into machine-washable fabric, capturing six physiological parameters — electrocardiogram, thoracic and abdominal respiration, skin temperature, pulmonary impedance, and physical activity — feeding its proprietary HOTS (Hierarchy Of Event-based Time Surfaces) neuromorphic algorithm, which performs data fusion to detect changes in patient status and predict acute pathological episodes.

Underlying the product portfolio is an interoperable architecture spanning textile sensors, a smartphone application, and a web visualization interface, with integrations into third-party platforms including Garmin, Infiniwell's SentioWeb, Fitrockr, and TMM Software. Chronolife is ISO 13485 certified, GDPR compliant, and hosts data on HDS-certified health data servers in Europe, with a North American subsidiary in San Francisco supporting US market access.

The company operates a B2B enterprise model selling hardware (medical devices), recurring subscription-based remote monitoring services, and professional services for custom wearable development and pharmaceutical clinical trial support. It targets patients with chronic pathologies (heart failure, respiratory disease, oncology), athletes and sports medicine programs, defense and industrial workers (via partners such as SAMI Advanced Electronics, Mission First Solutions, Europrotect), pharmaceutical companies (Servier, Chugai), insurance mutuals, and home healthcare providers. Go-to-market relies on enterprise field sales, clinical validation partnerships with major hospitals (including Rigshospitalet in Denmark), and integration partnerships with telemedicine platform operators across Europe, Scandinavia, the Middle East, and North America.

Core offering

Chronolife designs, manufactures, and operates a multiparametric smart textile wearable platform for continuous remote health monitoring. Its flagship Keesense connected t-shirt is a CE Class IIa medical device that captures ECG, respiration, temperature, physical activity, and pulmonary impedance data, and applies its proprietary HOTS neuromorphic algorithm for predictive analytics. The company offers off-the-shelf products, subscription-based telemonitoring services, and custom wearable development through its Reference Design service.

Product overview

Chronolife operates an open ecosystem of digital health turnkey services for remote patient monitoring and early detection of deteriorating health conditions. The company relies on its own off-the-shelf or custom multiparametric connected medical devices as well as third-party devices for continuous monitoring. The product portfolio consists of three main offerings: Keesense (CE Class IIa certified connected t-shirt for cardiac rehabilitation and general patient monitoring), Smart Textile (for sports recovery and occupational health), and Reference Design (custom wearable development service). All solutions utilize Chronolife's proprietary HOTS algorithm for data fusion and clinical event detection, transmitting data via smartphone application to web-based interfaces for healthcare professional access.
