How I Built This with Guy Raz

What if the founder of one of the internet’s most enduring brands… never wanted to run a company?

In 1995, Craig Newmark was a 42-year-old computer programmer in San Francisco who simply wanted to share local tech meetups with friends. He started an email list that became Craigslist—a website that reshaped how we find jobs, apartments, and community.

In this conversation, Craig opens up about how not having a grand vision (or a taste for power) led to one of the most popular platforms in the world. With fewer than 50 employees, Craigslist still generates hundreds of millions in revenue—while looking like a website frozen in 1996.

This is the story of an “accidental entrepreneur” who built a global brand by being in the right place at the right time—and why he now calls himself the Forrest Gump of the Internet.

In this episode, you’ll learn:

 • Why keeping things simple is often the smartest design choice.
 • How knowing your weaknesses can be the ultimate superpower.
 • Why community beats marketing every time.
 • How to monetize 
minimally • —and still build a wildly profitable company.
 • Why luck and timing matter more than you might think.

Timestamps:

 • 07:10 Craig’s childhood struggles with social situations—and how local Holocaust survivors shaped his worldview
 • 16:15 Discovering the early internet and becoming an “evangelist” at Charles Schwab
 • 20:07 The simple email list that broke at 240 addresses—and became “Craig’s List”
 • 29:16 Why Craig refused banner ads and said no to early monetization
 • 35:00 Handing the CEO role to Jim Buckmaster—and how that decision led to Craigslist’s success
 • 49:44 eBay buys a stake in Craigslist, then launches a competitor—sparking a messy legal battle
 • 53:46 Was Craigslist really responsible for killing newspaper classifieds? Craig reveals his opinion
 • 58:08 Why Craig gave hundreds of millions of dollars to support journalism, veterans, and… pigeons
 • 1:03:10 Craig on money, meaning, and why billionaires are often miserable

A decade ago, Allison Ellsworth was drinking apple cider vinegar for health reasons and doctoring it with fruit so she could stand the taste. Her husband Stephen helped her turn it into a business by adding carbonation on a hacked soda line in their Dallas townhouse. They called it “Mother Beverage,” and sold out every week at the farmers market…but then heard the words no founder forgets: “Your branding is…sh*t.” 

What happens next is one of the wildest CPG glow-ups of the 2010s: a Shark Tank deal with brand whisperer Rohan Oza, a full rebrand to Poppi, colored cans that jumped off the shelf, a launch derailed by Covid—and finally, an explosion fueled by Amazon, TikTok, and a Super Bowl moment that planted the flag: We’re soda–and we’ve left the farmers market for good. 

Five years after its rebrand, Poppi was acquired by Pepsi for nearly $2B. This is the story of the messy bottling line, saying no to “dumb money,” baptism by Shark Tank, and building a generational brand while staying married.

In this episode, you’ll learn:

 • How rebranding can rescue a beverage, and when to avoid early eye-rolls 
 • The hit-and-miss of carbonating on a small scale (and why co-packers said no).
 • How the risky decision to call Poppi “soda” unlocked a new retail set (functional soda).
 • What a Shark Tank partner does during a rebrand window.
 • How Allison seized on TikTok to spike sales during Covid 

Timestamps:

 • 0:10:15 Meeting cute at a snowboard shop → engagement in 7 months 
 • 0:14:00 How apple cider vinegar helped Allison’s health…but tasted terrible (early flavor hacks) 
 • 0:22:36 DIY carbonation disasters: exploding bottles & the 40°F lesson 
 • 0:37:48 Appearing on Shark Tank while nine months pregnant and the deal with Rohan: “your branding is sh*t.”
 • 0:42:28 Selling out at the Dallas Farmers Market 
 • 0:47:02 The nail-biting rebrand from “Mother” to Poppi: colored cans vs. white, and winning the shelf 
 • 0:55:43 Expo West canceled by Covid → a massive turnaround fueled by Amazon, Shark Tank, and TikTok
 • 1:07:51 Super Bowl ad– “We’re soda!”--and the road to a ~$2B Pepsi acquisition 
 • 1:09:58 Growing a business while managing a marriage

Many of us don’t know our neighbors anymore — and Nirav Tolia wanted to change that. He walked away from millions in stock options at Yahoo and eventually co-founded Nextdoor, the hyperlocal social network where neighbors share local news and recommendations. Along the way, he learned that for a digital service, Nextdoor demanded a ton of manual work: drawing neighborhood boundaries with Sharpies, sending individual “invite” postcards by snail mail, talking to neighbors about the information they wanted. After 8 years of grind, Nirav stepped away as CEO, only to return 6 years later to spearhead an ambitious rebrand of Nextdoor, which now has 100 million users around the world. 

In this episode, you’ll learn:

 • Why Nirav walked away from millions in stock options to launch his own business 
 • How the failure of an early business helped fuel Nextdoor’s success 
 • How not having an initial vision for your brand can be a superpower. 
 • Why apps that focus on “local” are so hard to master 
 • Why Nirav believes” local” is a massive untapped opportunity in tech.

In the summer of 2000, Razor scooters were everywhere—on sidewalks, in schools, even in Silicon Valley offices. At the center of it all was Carlton Calvin, an ex-lawyer turned toy mogul who had already ridden—and crashed—multiple crazes, from Pogs to yo-yos.

Carlton knew how to spot what kids wanted before the world caught on. But when Razor went from selling a million scooters a month to zero almost overnight, his business teetered on collapse.

This is a story about timing, obsession and instinct: knowing kids would snap up Slammers with scorpions inside, seeing the potential of a sleek new scooter from Taiwan, and learning how to turn a craze into a lasting global brand.

In this episode, you’ll learn:

 • Why most “overnight successes” collapse as quickly as they rise
 • The power of partnerships– and trust– in scaling quickly
 • How to think like your customer (in Carlton’s case, a 10-year-old boy)

Advice Line: Playing to Your Strengths

What does it take to turn a Brooklyn beer salesman into the king of iced tea?

In the early 1990s, the iced tea market was dominated by Lipton, Nestea, and Snapple. But Don Vultaggio saw an opening. A single moment—watching Snapple cases fly off a truck in winter—sparked an idea that would change his life: why not sell tea in a tallboy can? 

AriZona exploded—outselling Snapple and becoming a multi-billion-dollar brand. 

Behind the success was struggle: Don fought to keep the company private. and faced a painful 10-year legal battle with his former friend and co-founder. 

In this episode, Don reveals:

 • How he stayed independent in an industry dominated by giants. 
 • Why Snapple stumbled after being acquired—and how AriZona avoided the same fate.
 • Why he wants AriZona to remain a multi-generational family business.

In the early 2000's, Philip Krim launched an e-commerce business out of his college dorm, selling everything from window blinds to eczema cream to yes, mattresses. Years later, inspired by online successes like Warby Parker and Harry's, Philip and his partners launched Casper, a DTC company that designed its own mattresses, compressed them into boxes, and helped turn a mundane purchase into an Instagrammable adventure. Within months, sales began to take off; and soon, copycat brands crowded into the DTC mattress space, creating competition and buzz in a previously sleepy sector. (Pun unavoidable) Despite these challenges, Casper's valuation soared to $1 billion in 2019, only to shrink by half for its 2020 IPO. Today, Philip says he's focused on the future, with ambitions to build Casper into a one-stop-brand for all things sleep-related.
