Calm: Alex Tew and Michael Acton Smith

How I Built This | May 26, 2025

As a young entrepreneur in the Wild West days of the internet, Alex Tew was drawn to meditation for its simple calming power. Together with fellow tech founder Michael Acton Smith–known for hits like Moshi Monsters–the two brainstormed ways to bring the ancient practice of meditation into the 21st century. In 2011, they bought the domain calm.com, built an app, and started producing meditations and Sleep Stories, narrated by celebrities like Matthew McConaughey and Idris Elba. Despite initial pushback from investors who insisted no one would want to meditate on their phone–let alone pay for it– the Calm app grew to a valuation of nearly $2 billion, with 180 million total downloads.

This episode was researched and produced by Katherine Sypher with music composed by Ramtin Arablouei. It was edited by Neva Grant. Our engineers were Patrick Murray and Robert Rodriguez.
