From herd
to sovereign.

Jamarlin Martin is a Black American business owner (descendant of slaves in Mississippi and Louisiana) residing in Florida and founder/CEO of KOS Book Publishing, LLC. Prior to his successful digital media career, Martin graduated from Morehouse College. He attended Syracuse University College of Law and worked as a contract paralegal at Paul, Weiss on the famous Jack Grubman–Salomon Smith Barney case involving conflicts of interest.

Learning from his experience analyzing Grubman's emails, he developed expertise in identifying fraudulent conflict structures and later flagged the relationship between FTX and Alameda Research — identifying brokerage and proprietary trading conflicts as predictive of massive fraud years before the case made history. After commissioning an article exposing these conflicts, Dan Friedberg, Chief Counsel for FTX and Alameda, personally emailed Martin wanting to discuss his concerns, demonstrating his prescient ability to identify systematic fraud in complex financial structures.

The same pattern-recognition skills produced another historic call. In an August 8, 2017 article, Martin publicly named Silicon Valley Bank as ground zero for a popping Silicon Valley bubble — making him the first American to publicly flag the risks related to SVB. He submitted the short thesis to Seeking Alpha for syndication, but its editors declined it as "over the top". Six years later, in March 2023, Silicon Valley Bank collapsed, federal regulators and the Federal Reserve intervened with emergency measures to contain the fallout, and SVB Financial Group filed for bankruptcy. FTX and SVB tell one pattern story: the same trained eye that spotted crypto's largest fraud also spotted what became, at the time, the second-largest bank failure in U.S. history — years before either made headlines.

Martin has also previously worked as an independent contractor at McKinsey & Company. He is a recognized expert in paid discovery marketing. He is an EY Entrepreneur of the Year award recipient, named to Ebony Magazine's 100 Most Influential Black Americans, featured in Fortune Magazine's David vs Goliath column, and was an American Political Science Association Ralph Bunche Fellow studying graduate-level political science courses as an undergraduate at the University of Virginia.

In 2013, Inc. Magazine named Martin's company Moguldom Media Group the 11th-fastest-growing media company in the United States in its Inc. 5000 ranking. While pioneering digital analytics science and developing audiences for blogs, he built a portfolio of blogs with over 20 million monthly users and $20 million in annual revenue before selling his portfolio to Nasdaq-listed Urban One. Martin started his digital media career with a $6 GoDaddy domain name purchase and built his empire without venture capital.

Martin independently ran a multi-year, intelligence-grade investigation into the $140 billion global ad fraud industry — work that began before his February 2024 Securities and Exchange Commission whistleblower submission and continued after it. He applied the same discipline and analytical and data-science rigor that built his digital media business to the fraud that resulted in big advertisers such as Target, Amazon, and AT&T pulling their ad spend. His research was augmented with artificial intelligence and pointed to intelligence-linked and state-sponsored corporate fraud at American companies. The investigation uncovered systematic ad fraud — and elevated risks of obstruction and conflicts of interest involving his paid legal representation.
