Amy Errett had a successful career in finance and venture capital before taking a leap into an entirely new business: hair color. When her wife complained about the indignities of coloring her hair at home, Amy realized the sector was ripe for a makeover. At age 56, she dove into the minutiae of dyes and developers, launching her own formula in 2013, and naming it after her daughter. Madison Reed’s early successes were marred by a management meltdown, when Amy had to break with three of her co-founders—an experience she describes as one of the most difficult of her life. Today Madison Reed is available in thousands of stores across the US, and runs nearly 100 of its own salons.

In 2021, Daniel Humm shook up the dining world by making his 3-Michelin-star restaurant, Eleven Madison Park, 100% plant-based.

No meat. No butter. No cream.

It was a first in fine dining, igniting global headlines, industry backlash, and endless debate.

Now, in an exclusive podcast conversation with Guy Raz, Daniel shares his next bold decision—he's reintroducing animal products. Daniel shares what he learned from his years of plant-based cooking and how the experiment forever changed his creative vision.

This is a story about risk, reinvention, and the relentless pursuit of excellence.

In this episode:

• How a creative rut at the peak of his career sparked a radical transformation.
• The hidden economics of running a world-class restaurant without meat.
• The backlash—and surprising supporters—of the plant-based pivot.
• Why EMP will remain 90% plant-based, but welcome more people back to the table.
• What Daniel believes is the future of fine dining.

Crumbl may be a cookie business – but Jason McGowan turned it into a fast-growing restaurant chain by building it like a tech startup. He and co-founder Sawyer Hemsley meticulously A/B tested the recipe, launched a delivery app early on, and went viral with weekly drops of wild new flavors like bubblegum and Almost Everything Bagel. In just eight years, Crumbl has opened over 1,000 stores, and has dominated the cookie conversation on social media, with more TikTok followers than Starbucks, Domino’s, and Taco Bell combined.
