Don't overthink it. There is no brief, no agenda, just good conversations with interesting humans. We'll probably talk about relationships, food, spirituality, love, brand, fitness, dogs, entrepreneurship, living your best life, and other stuff we like, but we might not.
How to Build a $100M+ Brand Without Losing Its Soul | Kent Yoshimura & Ryan Chen
A neuroscience student mixing supplements in his dorm room. A national kendo competitor who became paraplegic at 19 after a snowboarding accident. Best friends. And then, one scuba diving Groupon later — a company.Jon Bier sits down with Kent Yoshimura and Ryan Chen, co-founders of Neuro, for a conversation ten years in the making.
Jon was there early. He gave them his first ever angel check. He watched the whole thing — the grinding first seven years on $1.6 million raised while every other DTC brand was burning through $30 million, the Shark Tank appearance that got them zero deals and exploded their sales, the trademark lawsuit that nearly ended everything, the near-billion dollar brand they built without ever compromising the formula.
This isn't a success story. It's a story about what success actually looks like when you build it the right way — slowly, stubbornly, and with your friendship completely intact.
Jon has been saying it for a decade. This is the episode where everyone else gets to hear why.
In this episode:
• How Neuro went from clinical trial side income and Craigslist employees to one of TikTok's top-selling brands and why raising less money than everyone else turned out to be the advantage
• The Shark Tank story nobody tells: zero deals, a trademark lawsuit, a cold DM to a billionaire, and the moment everything changed
• Why Kent and Ryan have never cut a corner on the formula and what it actually means to be a brand-led company in a world that rewards sales-led thinking

You're optimizing your supplement stack. You're tracking your macros. You're sleeping eight hours. And you're washing it all down with water that's sitting in plastic that's been baking on a truck in 100 degree heat for three weeks.
Jon Bier sits down with Clara Sieg — co-founder of Loonen and former venture investor — for a conversation about the most overlooked input in the entire wellness conversation. Water. The category that built its entire identity on pictures of waterfalls and asked consumers to just trust them. Clara got pregnant, started paying attention, and found out that no natural source in the US she tested was entirely free of contaminants. So she built something that paired spring sourcing with stainless steel processing, physical membrane filtration, and NSF certification — and put it in glass. Every time.
This isn't fear mongering. It's just information and most people don't have it.In this episode:• Why 50% of US tap water tests positive for lead and forever chemicals and why the bottled water sitting in plastic on a hot truck might not be solving the problem you think it is• How Clara went from a panic during pregnancy to six months testing water sources across the US, and why every single one had a footnote• What it actually takes to build a cleaner water brand in the most competitive, public-company-dominated beverage category on the shelf and why being naive enough to start was an advantage.

The Startup Disrupting a $7 Trillion Industry l Jess Haghani

Every single grocery store aisle has been disrupted by better-for-you brands. Every one — except the aisle where the fastest-growing demographic in America shops for nutrition.
Jon Bier sits down with Jess Haghani — founder and CEO of Lucille Health — for a conversation about what happens when you spot a gap so obvious it feels impossible that no one has filled it yet. Jess watched her grandmother, Lucille, come home from heart surgery and get handed the same ultra-processed nutrition shakes that haven't meaningfully changed since the 1970s. Products people hide in their basements. Products they're embarrassed to let their grandkids see. A $6 billion category with zero dignity, zero innovation, and no real competition.
So she left KKR, went to Harvard Business School, and built the brand she knew had to exist.
This episode is a little different. Jess hasn't built a nine-figure business yet. But Jon believes she will and this conversation is why.
In this episode:
• Why less than 1% of food and beverage innovation is happening for older adults, despite them being the fastest-growing consumer demographic in the world — and why that gap is finally closing
• The real story behind Lucille: how watching her 92-year-old grandmother hide a nutrition shake in her basement became the founding moment of a brand built around dignity
• What it looks like to take on Abbott and Nestlé with no money, no formulation experience, and no playbook and why that might actually be the advantage
