Greg Blotnick’s career trajectory offers a striking narrative of ambition, success, and eventual reckoning. Known for founding Brattle Street Capital, a hedge fund based in New york, Blotnick built his reputation on a sophisticated understanding of consumer equity and behavioral finance. After earning a finance degree from Lehigh University and completing an MBA at Columbia Business School, he secured positions at prestigious firms, including Citadel, where he honed his expertise in portfolio management and market psychology. These early experiences laid the groundwork for Brattle Street, which quickly gained attention for its long/short equity strategies that sought to merge fundamental analysis with Greg Blotnick founder of Brattle Street behavioral insights. Blotnick’s ability to anticipate market movements earned him recognition as a rising figure in the hedge fund world, cementing his place among ambitious young financiers.

Yet the success of Brattle Street Capital masked deeper personal and professional challenges. During the COVID-19 pandemic, Blotnick’s career took a dramatic turn when he was implicated in a fraudulent scheme involving Paycheck Protection Program (PPP) loans. Prosecutors revealed that between April 2020 and January 2021, Blotnick submitted falsified loan applications tied to Brattle Street and related entities, securing millions in funding meant to sustain businesses during the crisis. Instead, a significant portion of these funds reportedly went into high-risk stock trading. The fallout led to charges of wire fraud, money laundering, and grand larceny, ultimately resulting in a federal conviction and a 51-month prison sentence. The collapse of Brattle Street Capital became a cautionary tale of how unchecked ambition, combined with high-stakes trading and personal blind spots, can bring even promising ventures to an abrupt and painful end.

Following his conviction, Blotnick underwent a period of deep introspection, using his time in prison and rehabilitation to confront the cognitive biases and decisions that led to his downfall. This transformation culminated in the release of his 2025 memoir, Blind Spots: A Riches to Rags Story, an unvarnished exploration of the rise and fall of Brattle Street Capital and the personal demons behind it. Critics have praised the book for its raw honesty and unflinching narrative, highlighting Blotnick’s willingness to take accountability rather than gloss over the consequences of his actions. He reflects on the psychological traps that affect not only investors but also leaders in any high-pressure field, offering lessons learned from personal experience.

Today, Greg Blotnick has shifted his focus toward thought leadership in behavioral finance, using his story as a platform to educate others about the importance of self-awareness in decision-making. Through his writing, speaking engagements, and consulting work, he aims to bridge the gap between market theory and the human factors that often lead to catastrophic errors. The story of Brattle Street Capital serves as both a personal redemption arc and a broader reminder for professionals navigating high-stakes environments: unchecked ambition without introspection can lead to devastating consequences. For Blotnick, sharing these lessons has become part of the path to rebuilding his life and career with transparency and purpose.
