The Best One Yet - 💄 “Makeup King” — Elf Beauty CEO Tarang Amin’s Interview with TBOY
The CEO of e.l.f. Beauty says charging $38 for lip oil is "immoral."
In this fun exclusive interview, e.l.f.’s CEO Tarang Amin explains why he thinks big profit margins are unethical and how his biz creates "dupes" better than the lux originals… for a fraction of the price.
So we glammed up with Tarang to break down the economics of the $3 lipstick, how e.l.f. legally copies rivals like Dior, and why he shares the company's "nuclear codes" with every employee.
Of course we got all the details on his acquisition of Hailey Bieber’s Rhode Skin for $1B, the fastest-growing beauty brand in America (spoiler: It all went down over a dinner in LA).
And there’s even an investment angle: Wall Street fell in love with $ELF stock as it rose 800% in just a few years. While tariff fears recently cooled the price, Tarang explains what investors are missing in the mirror… And why that epic Hailey Bieber’s Rhode deal was a true makeover.
(Plus, Tarang helped Jack add another cream to his 42-step skincare routine)
Some of the Takeaways & Insights:
- "It's Immoral": Tarang’s controversial take on why charging $40 for lip oil is a scam.
- The $38 vs. $8 Math: How e.l.f. beats luxury brands at their own game

- The $1B Rhode Deal: The inside story of buying Hailey Bieber’s company.
- S&: Why "Scrolling & Development" (reading TikTok comments) beats traditional innovation.

Good Bad Billionaire - David Geffen: The Hollywood power broker
David Geffen is the money man behind Crosby, Stills and Nash, Guns N' Roses, Cher, Shrek, Gladiator, and even Cats the musical. Journalist Zing Tsjeng and BBC business editor Simon Jack tell the remarkable story of the Brooklyn boy who conquered Hollywood and became an entertainment mogul. From starting in a New York agency mailroom to the heart of Laurel Canyon’s hippie-rock scene, David Geffen rubbed shoulders with almost every major cultural figure of the 20th century. Joni Mitchel wrote a song about him, and Cher dated him. Then he moved from the music industry to movies, founding DreamWorks with Steven Spielberg and building one of the world’s most valuable art collections. Good Bad Billionaire is the podcast that explores the lives of the super-rich and famous, tracking their wealth, philanthropy, business ethics and success. There are leaders who made their money in Silicon Valley, on Wall Street and in high street fashion. From iconic celebrities and CEOs to titans of technology, the podcast unravels tales of fortune, power, economics, ambition and moral responsibility. Simon and Zing put their subjects to the test with a playful, totally unscientific scorecard — then hand the verdict over to you: are they good, bad, or simply billionaires?
