Creating Muse: The Fastest-Growing AI Product Since ChatGPT | Alexandr Wang, Meta
Oct 11, 2026 · 1:12:17
David Senra interviews Alexandr Wang, Meta's chief AI officer and co-founder of Scale AI, about building Muse, which Wang calls the fastest-growing consumer AI app of all time with 'millions' of users. Muse grew from Nat Friedman's OpenClaw experiments into a one-week prototype demoed to Meta's board in February, then a seven-month build by a team of under 200 to make a reliable personal agent. Wang argues Meta bet on personal AI over coding agents because its heritage and 3.5 billion daily users make consumer AI its edge, and he describes marketing Muse with memes to make Meta cool again. He recounts Zuckerberg's call after the Llama 4 setback, leaving Scale after nine years as Meta took 49%, and rebuilding Meta's AI lab as a flat, anti-bureaucratic team with over 200 direct reports.
