We’re on a mission to conquer sleep. The adventure begins now.

Understanding and improving sleep is one of the most important technological, scientific, and societal undertakings of our time. Sleeping well is not a luxury; it's an absolute necessity. Unsatisfactory solutions and a lack of understanding have caused us to sacrifice our sleep for too long. It's time to act; it’s our mission.


Our funding dates


Jan Born, a neuroscience researcher at Germany’s Tübingen University, proved that using sound stimulation at specific moments during deep sleep can significantly influence the rhythm of brain slow waves, and thus improve the quality of deep sleep. This promising discovery was the impetus for creating Rythm, our company.

Hugo Mercier and Quentin Soulet de Brugière launched Rythm. They surrounded themselves with ambitious and talented engineers and built a world-class team. They started researching and developing major tech innovations to apply the original scientific concepts. During this process, we filed no fewer than twenty patents.

After two years and 12 million euros in funds raised, the Dreem team grew to over 50 people. In 2016, we launch a beta version of our Dreem headband. We picked 500 beta-testers out of nearly 10,000 applicants from France, the United States, and the United Kingdom to participate in our "Dreem First" program. Within six months, we collected user data for more than 45,000 nights spent using Dreem.

We partnered with Paris's Hôtel Dieu hospital to conduct independent clinical trials on the Dreem headband. We proved its ability to track sleep with unprecedented accuracy and efficiently stimulate brain activity during the deep sleep stage. This was a major milestone: we managed to replicate the original scientific discovery outside the lab, simply using Dreem.


One year after the beta test, we officially introduced the Dreem headband to the general public and opened pre-orders. The latest version of Dreem is more compact, lighter, and has new features. After years of work and hundreds of iterations, we finally launched the world’s first comprehensive sleep solution.

White paper

To go even further and push sleep research forward, we inaugurated the Adventurers Program, the first remote research program on sleep. Involving several thousand participants, it will allow us to better understand sleep and develop new techniques to improve it.
