In 2004, Eric Hochberger co-founded Mediavine, which would eventually become one of the most influential ad management companies on the open web. The company didn't start as an ad tech firm — it began as a scrappy collection of SEO-fueled fan sites, built by three founders chasing traffic in the early blogosphere. While selling $50 sidebar ads and offering SEO consulting services, Eric and his partners learned firsthand how fragile and inconsistent early digital advertising could be. That experience ultimately pushed Mediavine to build its own header bidding system in 2014, a move that quadrupled the company's ad revenue and transformed it from a publisher into an ad management platform.

Today, Mediavine represents roughly 17,000 publishers and operates with a 140-person team, primarily serving independent creators rather than legacy media brands. In a recent interview, Eric pulled back the curtain on how programmatic advertising actually works, why "made-for-advertising" sites are siphoning off industry dollars, and how Google's AI Overviews are reshaping traffic patterns — sometimes wiping out entire businesses overnight.

Michael Fritzell doesn't fit the typical profile of a newsletter writer. Before launching Asian Century Stocks, he spent 15 years inside the machinery of global finance — working in investment banking and eventually managing money for a wealthy family in Singapore. A Swedish native who studied Chinese at Peking University, Michael built a career analyzing overlooked equities across China and Southeast Asia. When he struck out on his own to launch the Asian Century Stocks newsletter in 2021, he wasn't experimenting with a side hustle — he was walking away from a traditional finance track to build a niche media business focused on Asian stocks that most Western investors ignore

Launched on Substack and now operating independently, Asian Century Stocks sells in-depth, 40- to 60-page research reports to paying subscribers, many of whom are professional investors accustomed to paying banks tens of thousands of dollars a year for comparable research. Michael positioned himself as a bridge between local Asian markets and global capital — offering deeply reported, independent analysis without the conflicts that often accompany sell-side research.

In an interview, he explained how he went from anonymous finance professional to six-figure recurring revenue newsletter operator, why he ultimately left Substack for Ghost, and what it takes to monetize serious financial research in a tightly regulated industry.
