How JJ Hornblass built Royal Media, the most successful B2B media company you've never heard of

My newsletter: https://thelongstory.substack.com/   When JJ Hornblass got his first journalism job in the 1990s, his dad made a deal with him: he could spend a few years as a reporter, but he had to eventually make his way over to the revenue side of the media business. It only took JJ a few years to follow through on that deal.   While working as an editor at American Banker, he pitched his bosses on launching a print newsletter covering the mortgage securities market. When those bosses took too long to make a decision, he left his job to launch the newsletter on his own. Flash forward 30 years, and that newsletter has grown into Royal Media, a B2B media company that covers four niche industries.   In a recent interview, JJ explained where he found his initial subscribers for that first newsletter, how he expanded into new verticals, and why he's so focused now on building and selling access to data platforms.
