How I Built This with Guy Raz

What if the idea that changes your life… starts with something as ordinary as being thirsty?

In 2007, Travis Rosbach walked into a sporting goods store looking for a water bottle—and stumbled onto a problem no one had solved. Plastic, BPA-lined bottles dominated the market. Metal alternatives leaked, dented, or couldn’t keep drinks cold enough. 

Travis’s solution? A double-walled, vacuum-insulated, stainless steel bottle. His expertise? Non-existent. 

This is the improbable story of how Hydro Flask was built—from scavenging metal parts in China, to selling bottles at outdoor markets, to getting into Whole Foods by sheer timing and luck, to a last-minute investor who walked in on the day Travis planned to shut the company down.

Hydro Flask would go on to become one of the most recognizable and popular bottles in the country. 

This is the story behind it.

Advice Line with Anthony Casalena of Squarespace

At 19, Ben Francis was lifting weights during the day and delivering pizza at night. He didn’t have money. He didn’t have fashion experience. He didn’t even know how to sew. What he did have was a front-row seat… to a new online trend. Before Instagram and influencers became a strategy, a handful of YouTubers were redefining gym culture — building identity and community online. 

With his gymwear brand Gymshark, Ben didn’t try to compete with Nike. He didn’t try to buy ads. He did something much more powerful: He built relationships. He sent free T-shirts to the Youtubers he admired. He learned what gym-goers actually wanted to wear: tapered tracksuits, and shirts that emphasized their muscles.

Today, Gymshark is valued at more than a billion dollars, and Ben is the youngest billionaire in the UK. But his story is not just about business. It’s about identity, discipline, humility—and learning to grow as fast as you can learn. 

What You’ll Learn: 

 • How to build a brand by building community first 
 • How to hire smart people without losing control of your company
 • Avoiding imposter syndrome by creating your own apprenticeship program 
 • How to get stronger by staying in your lane 

Timestamps: 

06:15 - The IT education that changed Ben’s life

17:48 - Gymshark’s first sale: a £2 profit that had him dancing in his bedroom

20:06 - Early apparel—Screen-printing T shirts, a single sewing machine 

23:50 - How YouTube bodybuilders became their best marketers 

40:48 - How Ben hired his own boss–and what he learned from him

47:44 - Expanding to the US: a bone-chilling trip to Ohio 

50:35 - The bodybuilder’s aesthetic: big shoulders, narrow waist

53:58 - The painful breakup between Ben and his co-founder 

1:04:49 - Why he earned the nickname “Hurricane Ben.” 

1:12:30 - A legacy company: Resisting the urge to grow beyond the gym 

1:19:19 - Small Business Spotlight

Advice Line with Chet Pipkin of Belkin International

In his 20’s, working an office job he hated, Tom woke up in the middle of the night with a wild idea: why not take people on bike trips? No playbook. No investors. Just a sense that he could make a living doing what he loved. His first trip? Four guests riding through Death Valley, pitching their own tents. From there, Backroads scaled to hotels, while weathering a bike burglary, a van rollover in the desert, 9/11, the Great Recession, and a pandemic that brought tourism to a halt. 

Today, Backroads runs 5,000+ trips a year in 60+ countries.

This is a masterclass in savvy cash flow, scrupulous quality control, and dogged iteration. If you care about travel, brand, or building a services business at scale—listen to this.

 • How a 5,000 mile solo bike trip laid the groundwork for Backroads 
 • The first guided trip in Death Valley: four people, high winds, 50 miles/day 
 • How to get your stolen bikes back: confront the thief yourself 
 • The “collect early, pay late” flywheel that powered growth without investors
 • How Backroads survived 9/11, 2008, and COVID—and what changed after each shock
 • Avoiding the Instagram trap and delivering peak, uncrowded experiences

TImestamps:

 • 7:24 – Tom’s epiphany and the eight pages of notes that started Backroads
 • 10:15 – From cubicle to road bike: the solo trip that shaped the company’s DNA

In 2010, software engineer Natalie Gordon was pregnant– and fed up with the overwhelming baby aisles in big box stores. So she quit her computer job to code the registry she wished existed. No pink-and-blue giraffes. No allegiance to a single store. Just a universal list that let friends give the real help that new parents need—from strollers to diaper services to dog-walking.

Natalie coded the first lines of Babylist during her son’s nap time. She managed customer support, pitched bloggers from coffee shops, and learned growth the hard way—first through affiliates, then with a pivotal Pinterest bet, and finally by taking on her own inventory (and all the headaches that come with it). Along the way she wrestled with hiring, firing, fundraising, and the identity shift from founder to CEO. Today, Babylist is one of the most trusted parenting platforms in the U.S., with a retail arm, editorial content, and a program for providing breast pumps. 

This is a masterclass in living a problem–and building a solution. 

You’ll learn:

 • How to spot a customer pain point and design an MVP around it
 • The power of 
slow virality • How to use a small seed round without losing control
 • The painful path from affiliate revenue to first-party e-commerce
 • Stumbles with hiring – and firing– as a first-time CEO
 • How paid growth works on visual platforms like Pinterest
 • How “controlling your destiny” justifies a hard shift in business model
 • How coaching and feedback helps you evolve from founder to leader

Timestamps:

 • 05:32 - Learning to solve hard problems at Amazon -
 • 08:28 - Sabbatical in Latin America: Natalie’s first (failed) business and what it taught her
 • 17:50 - A meltdown in a superstore → the Babylist “aha” moment
 • 19:40 - Designing a universal registry, dog-walking included
 • 24:42 - Blitzing the mommy blogs, a “pregnant hacker” post on Hacker News
 • 30:01 - Why $140/month revenue felt like a victory
 • 39:18 - Going solo at an Accelerator, and the agony of early hiring and firing
 • 49:29 - From “slowly viral” to real scale, and how Pinterest helped
 • 58:09 - Affiliate links to in-house inventory → piles of bassinets in the office 
 • 1:01:57 - COVID’s unexpected windfall, the health wedge (breast pumps & beyond)

Advice Line with Niraj Shah of Wayfair

A century ago, Jeff Braverman’s grandfather opened a peanut shop in Newark, New Jersey. By the early 2000s, the family business was doing $1M in sales and struggling to stay afloat. Jeff had a high-paying job in finance, but walked away from it to reinvent the business. His strategy? The internet. Something his dad and uncle knew nothing about.

What happened next is wild: an AdWords experiment that blew the doors off the budding online business; a slip on national TV where Rachael Ray accidentally renamed the company; 40,000 pounds of protest peanuts that crashed servers and landed them in the New York Times; a hilariously polarizing rap jingle; and a COVID surge that tested leadership—and humanity—every single day.

This is the blueprint for transforming a dusty, low-margin business into a profitable, $100M+ direct-to-consumer brand—while keeping it family-owned. It’s also a masterclass in earning trust, making risky bets, and scaling without losing your soul.

You’ll learn:

 • The mechanics of a paid-search playbook that 10x’d orders overnight
 • How to win over skeptical family members (and when to demand the keys to the store)
 • The exploding-deal etiquette of buying a premium domain
 • How an improvised rap-jingle can be stickier than a professional ad 
 • How Nuts.com built a robust B2B business alongside DTC
 • Crisis leadership lessons from the COVID floor 
 • When and how a leader should hire their replacement

Timestamps:

 • 00:07:08 — Cash registers, code words, and a Newark childhood inside the peanut shop
 • 00:13:42 — The “build a website” pitch at a Jersey diner 
 • 00:29:40 — 
December 4, 2003: • from 3 orders/day to 30 
 • 00:31:19 — Dad panics –”shut it off!”– Jeff doubles down on demand and ops
 • 00:35:26 — Losing the storefront to a hockey arena—and going all-in online
 • 00:42:29 — 
Jericho • fans send 
40,000 lbs • of peanuts to CBS: press, links, and leverage
 • 00:48:38 — Rachael Ray calls them “Nuts.com” by accident… and the $700k domain deal that followed
 • 01:00:51 — The notorious Nuts.com rap jingle: how an earworm took hold
 • 01:03:11 — Offices, microbreweries, and building a sticky B2B engine
 • 01:05:08 — COVID hits: 70% call-outs, factory safety, and leading from the floor
 • 01:10:18 — Handing the reins to a new CEO: leaning into strengths, not ego

After giving up diet soda, Kara Goldin started adding fresh fruit to her drinking water to make it more fun. This inspired her to create Hint water, a line of unsweetened flavored water beverages that are now available in over 30,000 stores nationwide.
