Five Lives

Five Lives, founded in 2019 by Xavier Louis and Sylvain Piquet, is a digital therapeutics company with headquarters in London and Tours, France, that developed a mobile application to assess and reduce the risk of dementia. The founders, who both came from families with medical backgrounds and had extensive experience in the tech industry, including at the brain training app Peak, were motivated to create a purposeful company to address dementia prevention.

The direct-to-consumer app, also available for B2B partnerships, is designed to detect and lower the chances of developing dementia by managing five key lifestyle areas: nutrition, sleep, physical activity, mood, and mental stimulation. Users begin with a risk assessment based on a machine learning algorithm, which was trained on data from over 300,000 individuals in the UK Biobank study. This assessment provides a 10-year risk horizon for developing dementia. Based on the results, the app provides personalized coaching, educational content, brain games, and activities like music therapy to help users adopt healthier habits. For high-risk individuals, the app recommends a consultation with a doctor.

The company operates on a subscription-based model, offering a free trial before users pay an annual fee for full access to the app's features. In November 2022, Five Lives raised €3.7 million in a seed round led by Headline and Speedinvest to fund clinical validation and expand its user base in the UK, Australia, France, and Germany. The company is collaborating with the University of Oxford and Dementias Platform UK to clinically prove the app's effectiveness in preventing dementia.
