Our take

Calm is the world leader in digital wellness, specializing in helping users achieve healthier sleep, relaxation, and meditative practices. With over 150M downloads, Calm has firmly established itself as a top player in the rapidly growing wellness space, offering a web app designed to guide users toward better mental and physical well-being.

Born in 2012 following a chance meeting on a boat, co-founders Alex Tew and Michael Acton Smith bring a robust entrepreneurial skill set to the table. Having both achieved early successes and mental stresses with previous ventures ‘Million Dollar Homepage’ and ‘Moshi Monsters’ respectively, they set out to make online mindfulness available to the mobile generation.

Since hitting unicorn status in 2019 with $88m in Series B funding, Calm has gone from strength to strength in a fiercely competitive market. According to analysis service Sensor Tower, over 5,000 meditation apps have been launched since 2015. Calm is banking on innovative partnerships with UMG (the world's largest music company), HBO Max and additions of stars like Stephen Fry, Sam Smith and Matthew McConaughey to keep them firmly in their number 1 spot.
