Nick Allen Turned a Sunday Ritual Into a Company
Before Sunnyside was an app, it was a weekly plan, a few text messages and a founder paying close attention to what people actually did.
Arianna Huffington Has Changed the Subject Again
She built a publication around the internet's appetite for more. Her second company is built around a harder proposition: that progress can begin with less, done deliberately.
Andrew Shakman Put a Scale Under the Trash - and Made Every Scrap Confess
A film-school storyteller walked into a commercial kitchen, noticed an invisible leak, and spent two decades teaching scales, cameras and cooks to speak the same language.
Ashley Rose
Ashley Rose is the co-founder and CEO of Living Security, the Austin-based company that turned dull compliance-checkbox security training into a data-driven discipline it helped name: Human Risk Management. She built the company in 2017 with her husband Drew, starting with in-person cyber escape rooms and scaling into an AI-native platform used by enterprises like Mastercard, Verizon, CVS Health and JPMorgan. A product-obsessed entrepreneur who once funded a kids' snap-change swimwear line on Kickstarter, Rose argues the industry has the human problem backwards: people are not the weakest link, they are the largest attack surface worth investing in.
Jack Gardner
Jack Gardner is the founder and CEO of Kickoff, a New York wellness platform that pairs everyday people with certified personal trainers over text, video and an app for a fraction of in-person prices. An NASM-certified trainer himself, he built the first version while coaching his own mom, then turned that into a marketplace of 20,000+ coaches that has paid out millions to trainers and helped tens of thousands of clients. Before Kickoff he was a Bain consultant and a BuildZoom SVP; today he runs the company on a Notion-and-Metabase stack with a mission to make elite coaching something that doesn't require an elite bank account.
Mel Robbins
Mel Robbins is a bestselling author, award-winning podcast host, and one of the most-booked motivational speakers in the world. The creator of the 5 Second Rule and The Let Them Theory, she turned a near-bankruptcy crisis at 41 into a media empire with 40 million followers, a top-3 global podcast, and books translated into 65 languages. As CEO of 143 Studios, she produces content for corporate partners including Starbucks, JPMorgan Chase, and LinkedIn.
Sharam Fouladgar-Mercer
Sharam Fouladgar-Mercer is the Co-Founder and CEO of Signos, the company behind the first FDA-cleared over-the-counter glucose monitoring system for weight management. A Princeton computer science graduate and Harvard MBA, he played NCAA Division I ice hockey before building a career spanning VC at Sierra and Shasta Ventures, co-founding PR tech company AirPR (later Onclusive), and ultimately creating Signos in 2018 after his own lifelong struggle with weight and the death of his diabetic grandmother inspired him to ask: why wait until someone is sick to give them metabolic data?
Julia Hu
Julia Hu is the co-founder and CEO of Lark Health, an AI-powered virtual care platform managing over 30 million contracted lives. Born in Los Angeles to first-generation Chinese immigrants and raised largely by her father, Hu spent her childhood navigating an undiagnosed chronic condition that would ultimately reshape how she saw healthcare. She dropped out of MIT Sloan mid-MBA to build what is now one of the largest CDC-recognized diabetes prevention program providers in the country, having raised over $257 million and earned recognition from Forbes, Inc., and the UCSF Health Awards Hall of Fame.
Nir Eyal
Nir Eyal is an Israeli-American behavioral designer, author, and angel investor best known for the 'Hooked Model' - the four-step framework used by the world's most habit-forming tech products. His 2014 book Hooked became a Silicon Valley bible for building engagement; his 2019 book Indistractable offered the antidote. His 2026 NYT bestseller Beyond Belief, co-authored with his wife Julie Li, tackles the hidden variable behind human performance: belief itself. A former Stanford lecturer, Eyal has backed companies like Canva and Kahoot, writes for the NYT and Harvard Business Review, and runs the influential blog NirAndFar.com.
