Author of Financial Cheat Codes

Sean’s debut book, Financial Cheat Codes, is a groundbreaking exploration of personal finance inspired by retro video games. Combining relatable metaphors with robust financial strategies, the book empowers readers to bypass common financial pitfalls, optimize passive income, and build generational wealth outside traditional investment frameworks.

Through humor and clarity, Sean unpacks complex topics like taxation avoidance, the Infinite Banking Concept (IBC), and legacy building, offering readers actionable “cheat codes” to master their financial futures. Resonating with seasoned investors and novices alike, Financial Cheat Codes reflects Sean’s unorthodox approach and his commitment to financial independence.

Beyond the book, Sean continues to inspire through seminars, podcasts, and speaking engagements, where he advocates for self-sovereignty and economic resilience. His expertise is deeply rooted in concepts championed by financial innovators like Robert Kiyosaki and Nelson Nash.
