The King of Content Marketing

Joe Speiser started his first business when he was still in middle school. The New York-based entrepreneur has had his hands in many industries, from DVD review sites to an ad network that brought in $200m in annual revenue. And that was just in his 20s.

Over the past two decades, he has become one of the country’s most successful content marketers. Among his hits:

• He started an e-commerce brand called PetFlow, selling pet food on a recurring basis. A pet blog he created helped bolster the business. The company quickly scaled to $65m in revenue.
• He spun off the pet blog into its own business, called LittleThings. Within months, LittleThings became one of the most popular sites on the web, growing to $5m in monthly revenue.

But like any content marketer, Speiser has had to contend with the fickle Facebook algorithm. Last year, a change in Facebook’s algorithm caused LittleThing’s business to dry up, forcing Speiser to branch out into new industries.
