In 2000, Luis von Ahn was starting his PhD in computer science when he attended a talk and happened to learn about one of Yahoo's biggest problems: automated bots were signing up for millions of free Yahoo email accounts, and generating tons of spam. Luis' idea to solve this problem became CAPTCHA, the squiggly letters we type into a website to prove we're human. He gave away that idea for free, but years later, that same idea had evolved into a new way to monetize language learning on the web, and became Duolingo. Today, Duolingo is a publicly-traded company with a market cap of $9 billion.

Five years before he became a massively successful content creator, Dhar Mann was nearly broke and living in a studio apartment. It’s the kind of story he might tell in one of his videos: bite-sized, live-action morality tales that have earned 60 billion views across YouTube, Facebook, and other platforms. Raised in an Indian Sikh family, Dhar had a strong entrepreneurial drive, which led to early business success, but also a spectacular downfall when he got pulled into a Ponzi scheme. A few years after losing nearly everything, he began making short, dramatic videos that conveyed life lessons. Nobody watched at first and critics called them cheesy, but today, Dhar has a huge production studio in Burbank, where dozens of  employees make content for tens of millions of subscribers.

Advice Line: Growing up on a Coffee Farm? Giving Back with Jewelry? Making the Perfect Pecan Pie?

With over 14.5 million subscribers, Rosanna Pansino has one of the most popular baking channels on YouTube But she never would have imagined her success back in 2010 when she started making videos as a hobby. At the time, she was a working actor in Hollywood with dreams of landing a leading role, but after receiving an ultimatum from her agent, she was forced to choose between a career in traditional television or the nascent digital world of YouTube. More than a decade after her fateful choice, Rosanna has come full circle with her dreams in entertainment as she hosts her own shows on The Food Network — while continuing to post on YouTube and adding to her catalog of over 1,400 videos with more than 4.7 billion views.

YouTube Creator and Cookbook Author: Rosanna Pansino

Growing up, Danielle Walker’s family often convened for big meals prepared by her Italian grandmother, Grandma Marge. Back then, Danielle enjoyed a wide variety of food without restriction; but she began experiencing severe abdominal pain in her 20s that ultimately led her to totally transform her diet—cutting grains, lactose, sugar and more. 

As Danielle found relief in this approach—and realized that others with similar ailments could as well—she began compiling her recipes in an online blog called Against All Grain. Before long, the self-taught chef became a bestselling cookbook author, more recently branching out with her own product lines and cooking courses. 

This week on How I Built This Lab, Danielle talks with Guy about being an ‘accidental entrepreneur’ as she chronicles her journey to building a multifaceted business centered around healthy eating. Plus, Danielle shares her advice for other creators looking to build an audience and discusses food’s potential to help millions suffering from autoimmune diseases.

Healing through food with Danielle Walker of Against All Grain (2022)

As one of the most successful creators on YouTube, Mark Rober doesn’t see what he does as a business. Instead, it’s a way to celebrate science in the most joyful way possible. While working as an engineer at NASA, he made his YouTube debut with a tutorial on how to make a gory Halloween costume with two iPads and a lot of duct tape. Over time, his videos became more elaborate, including a belly flop into a pool full of Jello, and a demo of a glitter-fart bomb to get revenge on porch pirates. Within a few years, Mark was teaching online science classes and selling subscription boxes for kids. Today, his YouTube channel has 5.5 billion views, 48 million subscribers…and–astonishingly, given that audience–less than 150 videos.
