Evolve (YC W18) builds consumer apps used by millions: Podcast App and Rest. Rest (getrest.app) is an AI sleep coach for people tired of bad nights — lying awake for hours or waking up at 3 AM. Built on CBT-I, the first-line method sleep clinicians recommend, it turns those principles into a daily program with a coach you can talk to at any hour — no appointments, no waitlists. Developed with sleep scientists and behavior-design experts, it helps people sleep well again without leaning on melatonin or sleep aids, with results people call life-changing. Podcast App is one of the largest independent podcast players: a minimalist app with tens of millions of downloads that uses machine learning to build playlists around what you like. The team has built consumer products with 100M+ installs and has been featured by Apple, TechCrunch, Yahoo, Fast Company, and Fox. Investors include Y Combinator, Floodgate, Reach Capital, and other Silicon Valley funds. Get in touch: hello@getrest.app.
